European Alternatives to Glean
Looking for a European alternative to Glean? Glean is run by Glean Technologies, Inc., a US company, and its privacy statement says personal information may be transferred to and processed in the United States. glean.com shows no price list (the pricing page leads back to the home page), so what a company pays is only known after talking to sales.
The European tools below index the same kinds of sources, such as file shares, wikis and business systems, from vendors registered in the EU, Norway or Switzerland, several with on-premises or private cloud installation and some with published prices.
How we rank these tools — 4-step process
-
1
European ownership, verified
The company is headquartered and incorporated in the EU, EEA, the UK, Switzerland or Israel, and processes customer data in Europe or Israel. A US parent company disqualifies a tool from this page regardless of where its servers are.
-
2
Category fit and hands-on review
What the tool actually does, who it suits, and where it falls short — checked against the vendor’s own documentation, changelog and pricing page rather than its marketing copy.
-
3
Compliance and pricing check
GDPR posture, hosting location and the prices quoted on this page are verified against the vendor’s public pricing before publication, and re-checked when we revisit the category.
-
4
Position on this page
Placement on this page can be paid, and that can affect which tools appear here and the order they appear in. It never buys a good review: a tool that fails the checks above is not here at any price, and payment does not change the shortcomings we write about. A vendor can ask us to correct a factual error — not to remove a criticism.
Vendors can pay for visibility on this page. It never changes what an entry says about a product, including the criticism, and we earn nothing when you click through to a vendor. Vendors can pay for more visibility, higher up on the review pages; it never affects which tools are listed. Editorial policy

Key takeaways
- Glean Technologies, Inc. is a US company, and its privacy statement says personal information may be processed in the United States.
- glean.com/pricing redirected to the home page on 27 October 2026, so Glean prices are only available through its sales team.
- Mindbreeze states 500-plus data source connectors against the more than 250 that Glean lists, but the figures count differently and should be tested against your own systems.
- IntraFind, Squirro and Intergator each state that the whole product can run inside the customer network, an option Glean does not describe on the pages read.
- Langdock, Ayfie and Zeta Alpha publish seat or platform prices, which lets a buyer set a budget before any sales call.
Why people leave Glean
Glean started as workplace search and now describes itself as an enterprise AI platform with an Assistant, an agent builder and a layer of model controls on top.
Its own site lists more than 250 connectors in the product menu, support for 40-plus language models, and security badges including SOC 2 Type II, ISO 27001, ISO 42001 and GDPR. For a company that wants one vendor to index Slack, Jira, Confluence, SharePoint and Salesforce and answer questions with permissions respected, it is one of the most complete products on the market.
The questions European buyers ask are different ones. The privacy statement on glean.com names Glean Technologies, Inc. as the controller, gives a postal address in San Francisco and says personal information may be transferred to, and processed in, the United States.
For transfers out of the EEA it relies on Standard Contractual Clauses and on a certification under the EU-U.S. Data Privacy Framework. That statement covers the website and business operations, not the product itself, so the terms that matter for your index sit in a contract you only see after a sales conversation.
That conversation is also where price appears. glean.com/pricing forwards to the home page, and the only call to action across the site is a demo request. Buyers who want a budget figure before involving procurement, or who need the index to sit with a vendor outside US reach, are the ones who start comparing European options.
- The contracting party is a US corporation Glean Technologies, Inc. is the entity named in the privacy statement, with a San Francisco address for privacy requests. A US-incorporated vendor can be served with US legal process for data in its custody, whatever region the servers are in. Glean certifies under the EU-U.S. Data Privacy Framework, which covers the transfer mechanism, but an enterprise index of contracts, tickets and HR files remains in the hands of a US company. The vendors on this page are registered in Germany, France, Austria, Norway, Switzerland and the Netherlands.
- No price list, only a demo request On 27 October 2026 glean.com/pricing redirected to the home page, and the site offers no seat price, no entry tier and no self-service trial. Budgeting therefore starts with a sales call. Among the European tools here, Langdock lists €25 per Standard seat per month, Ayfie lists its Index at €2,000 a month and its assistant from €15 to €20 per user, and Zeta Alpha lists a personal plan at €20 per month. Others also quote on request, but several publish at least a starting figure.
- You cannot see where the index lives The pages read for this comparison do not state a hosting region or an on-premises option for Glean, and the privacy statement says nothing about product data. IntraFind, Squirro, Intergator and Ayfie each state that the whole product can be installed inside the customer network, and Sinequa and Mindbreeze describe flexible deployment. If your security team requires the index in your own data centre, the answer from Glean has to come in writing from the vendor.
- Breadth you may not need Glean sells model routing, usage controls, an AI gateway, an agent library and content creation next to search. A company that mainly wants a good answer box over SharePoint and Confluence pays for a platform whose scope is far larger. Search-first European products such as IntraFind, Intergator or Mindbreeze cover the narrower job, and chat-first ones such as Langdock or Dust cover the assistant job at a smaller scale.
What you have to replace, not just match
Matching Glean means replacing four layers, not one. The first is the connector estate: the site names Slack, Google Drive, Jira, Confluence, SharePoint, GitHub and Salesforce on its home page and counts more than 250 connectors.
Check your own systems against each European vendor rather than comparing totals, because Mindbreeze states 500-plus connectors, Sinequa 200-plus and IntraFind 80-plus, while Ayfie, Intergator and Squirro publish lists by name instead of a figure. The second layer is permission handling. Glean says users only see what they are allowed to see, and every replacement has to prove that against your directory and your sharing settings.
The third layer is the assistant and agent surface. Glean offers an Assistant, an agent builder, orchestration, governance and a library of reusable agents.
A search platform like Sinequa or IntraFind brings its own assistant, but agent building is deeper at Langdock, Dust and Ayfie, and the open-source route through deepset gives you building blocks rather than a finished product. Decide which of these your staff actually use today; adoption data from your Glean admin console is the best input for that choice.
The fourth layer is the model choice. Glean states support for more than 40 language models and sells auto routing between them.
European products usually let you pick from a shorter list: Ayfie names GPT, Claude and Gemini, Dust names GPT-4, Claude, Gemini, Mistral and Grok, Langdock states that most of its models can be hosted in the EU, and the on-premises vendors can pair the index with a model that runs on your own hardware. Models from US labs often remain part of the chain, so the contract question moves from the search vendor to the model provider.

How each alternative compares to Glean
Langdock
Berlin chat and agent workspace with published seat prices and EU hosting
Best for: Companies that want an AI chat and agents for all staff at a stated per-seat price
Langdock GmbH of Berlin sells a model-agnostic workspace in which staff chat, build agents and run workflows. Against Glean the biggest difference is on the invoice: a Standard seat is listed at €25 per user per month excluding VAT, a Business Max seat at €99, and the Workflows add-on starts at €539 per workspace per month, with 20 percent off for yearly billing. A seven-day trial with €5 of model credits needs no credit card.
Its security page states that the multi-tenant SaaS runs on Microsoft Azure in the EU and that the application and most configurable models are hosted entirely there. It claims ISO 27001 and SOC 2 Type II and says customer data is not used for training. Bring-your-own-cloud is reserved for very large customers from 2,000 seats, and on-premises installation from 5,000.
What Langdock does better than Glean
- Published per-seat prices and a no-card trial
- Hosting stated as EU Azure with a German contracting party
- Workflow automation priced separately and visibly
Where Langdock is a step down from Glean
- Starts from chat and agents, not from a deep multi-system index
- Self-hosting only from 2,000 to 5,000 seats upward
- Fewer search-specific tuning options than Mindbreeze or Sinequa
Standout against Glean. The only tool on this page that puts a Standard seat, a premium seat and an automation add-on on one price list.
Best for: Nordic and mid-sized organisations that want an assistant grounded in case systems and documents
Ayfie (Ayfie International AS and Ayfie AS, Norway) splits the offer into a company index and an assistant on top. The pricing page shows the index at €2,000 per month, the assistant at €20 per user per month for 10 to 50 users and €15 for 51 to 300 users, an Enterprise tier from €3,990 per month above 300 users, and ready-made agents from €300 per month. Glean offers no comparable public figure.
Deployment runs from SaaS through private cloud to full on-premises installation with local model hosting, and users can reach the assistant from Slack, Teams or Copilot or through an API and MCP servers. Models from GPT, Claude and Gemini families can be chosen. Norway sits in the EEA but not in the EU, which matters only if a tender demands an EU entity.
What Ayfie does better than Glean
- A published index price and tiered per-user assistant prices
- On-premises and local model hosting stated on the website
- Directory-based access rights mirrored in the index
Where Ayfie is a step down from Glean
- Smaller connector footprint than Glean or Mindbreeze
- Norwegian company: EEA, not EU, and a Nordic reference base
- The index fee applies before any seat is counted
Standout against Glean. Splits the index fee from the per-user assistant fee, so you can see what the knowledge layer costs on its own.
Best for: Public bodies, courts, banks and insurers that want search and AI answers inside their own infrastructure
IntraFind Software AG in Munich (Munich District Court, HRB 134378) has built enterprise search for more than twenty years. Its iFinder search, the iAssistant chat and the iHub apps share one knowledge base with continuous permission checks, so an answer built from a document shows only what the asking user may open. Where Glean grew from search into agents, IntraFind sells a search core with AI added on top.
The site lists 80-plus connectors and hundreds of file formats, an Outlook add-in and a Confluence integration, and shows ISO/IEC 27001:2022. Deployment can be on-premises, hybrid, sovereign cloud or managed service. Pricing is on request, but a free trial of iFinder is offered, which gives a technical team a way to test without a sales cycle.
What IntraFind does better than Glean
- On-premises, sovereign cloud and managed options from a German AG
- A free iFinder trial in place of a demo-only start
- Long record with public administration, police and courts
Where IntraFind is a step down from Glean
- About 80 connectors against Glean's 250-plus
- Agent building is thinner than in Glean's platform
- No published pricing
Standout against Glean. A search-first product that can be installed on your own servers and still offers a chat assistant on the same permission-checked index.
Best for: Large organisations with many unlike systems that need one permission-aware layer
Mindbreeze GmbH, Honauerstrasse 2 in Linz (FN 262155y), makes InSpire, an insight engine that connects 500-plus data sources and preserves their permissions. Fabasoft AG owns 85.5 percent according to the imprint. Against Glean the notable point is the list length and the way authorisation is described: referenced access control lists and ahead-of-time computation, which suits very large result sets.
A Model Context Protocol server lets AI agents use the indexed knowledge, and the same engine is packaged for contract management, RFP handling and quality management. A partner programme allows software houses to embed it. The group also has a US subsidiary, Mindbreeze Corp. in Chicago, so a buyer who needs a purely European contracting chain should ask which entity signs the order form.
What Mindbreeze does better than Glean
- Connector count of 500-plus against Glean's 250-plus
- Flexible deployment, including customer-run installations
- Packaged applications for contracts, RFPs and quality management
Where Mindbreeze is a step down from Glean
- Pricing on request and project-style implementation
- Less self-service agent building than Glean
- Contracting entity must be confirmed because of the US subsidiary
Standout against Glean. States 500-plus connectors and exposes the whole index to external agents over MCP.
Best for: Regulated or public-sector organisations that want a French vendor and a private deployment
LightOn, a Paris company listed on Euronext Paris since 2024 (LightOn review), sells the Paradigm platform for on-premises or private-cloud generative AI. The EP review lists retrieval-augmented generation, fine-tuning, agents and an enterprise search and reasoning solution, and names the Ile-de-France region, Safran, Groupama and CNES as customers. Glean has the larger roster of global brands; LightOn offers French references from defence and public bodies.
The review also lists GDPR compliance and SOC 2 Type 1, with pricing on request and a demo as the way in. It says annual recurring revenue reached 1.9 million euros at the end of December 2025 and that hardware shortages slowed deployments, a useful fact when you plan a rollout. The company publishes retrieval models such as GTE-ModernColBERT on Hugging Face.
What LightOn does better than Glean
- Complete on-premises or private-cloud deployment under French law
- Public retrieval research and models
- Fine-tuning on customer documents inside the customer's infrastructure
Where LightOn is a step down from Glean
- Much smaller company and revenue base than Glean
- Quote-only pricing and a demo-led start
- Hardware availability can set the deployment pace
Standout against Glean. A listed French company that keeps documents, models and fine-tuning inside your own infrastructure.
Best for: Multinationals with SAP, ServiceNow and many languages that need a mature search engine
Sinequa is a French simplified joint-stock company registered in Paris under 442 599 213, marketed as Sinequa by ChapsVision. Its own comparison page states 200-plus native connectors, 350 document formats and natural language processing in more than 22 languages, so a question in one language can retrieve documents written in another. Typical sources named are SharePoint, Salesforce, SAP, ServiceNow, Jira and Confluence.
The platform pairs neural search with retrieval-augmented generation and lists assistants, agents and orchestration on its menu. Deployment can be cloud, on-premises or hybrid, and document-level access controls apply. Hosting regions for the cloud option are not stated and pricing is on request, so the cloud question needs a direct answer before signing. Ownership by ChapsVision is a point to include in due diligence.
What Sinequa does better than Glean
- Cross-language retrieval across 22-plus languages
- On-premises or hybrid deployment from a French company
- Two decades of search engineering behind the ranking
Where Sinequa is a step down from Glean
- Cloud hosting regions not stated on the pages read
- Implementation project rather than a quick start
- Fewer ready-made collaboration surfaces than Glean
Standout against Glean. Retrieval that crosses languages, backed by the most formats on this page (350).
Best for: Banks, insurers and government bodies requiring air-gapped or fully on-premises operation
Squirro AG of Zurich names itself as service provider in its website terms, applies Swiss law and sets Zurich as exclusive venue. It states that the complete GenAI platform can be installed fully on-premises, in a secure VPC or in an air-gapped network. Glean's pages describe no such option, which makes Squirro one of the few answers when the rule is that nothing leaves the building.
Components include semantic search, knowledge graphs, guardrails, a privacy layer, a classifier, taxonomy and ontology management, and an agent catalog that visitors can try without a sign-up. Switzerland is outside the EU, though it is a European jurisdiction. Pricing and a trust centre were not found on the pages read, so security documentation has to be requested.
What Squirro does better than Glean
- Air-gapped and on-premises delivery of the full platform
- Knowledge-graph and ontology tooling for regulated sectors
- Swiss contracting party with Zurich as the court
Where Squirro is a step down from Glean
- Not an EU company
- No published pricing or trust centre found
- Heavier project than a SaaS assistant
Standout against Glean. Delivers its complete platform into air-gapped networks, not a reduced offline edition.
Best for: German administrations, industrial firms and banks that want search on their own infrastructure
Intergator is made by interface projects GmbH in Dresden (HRB 8740, Amtsgericht Dresden). It comes in three editions: Core for search, and AI and AI+ for generated answers. The pitch against a result list is a summarised answer with the sources shown, which is the same experience Glean sells but delivered on-premises or in a private cloud.
Version 6.8, announced in September 2026, adds an agentic chat and better hybrid search, and a Microsoft Teams plugin carries the assistant into daily chat. The product is packaged for knowledge management, social intranet, website search, patent search and compliance monitoring. Connector counts and pricing are not published, so scope has to be agreed in a project conversation.
What Intergator does better than Glean
- On-premises or private cloud by default
- Core edition for plain search without generative features
- German public-sector and industry focus
Where Intergator is a step down from Glean
- No published connector figure or price
- Smaller international reference base
- Agentic chat is a new release in 6.8
Standout against Glean. Three editions let you start with plain search and add AI answers later.
Best for: Teams building custom AI agents on cloud tools with permission-scoped data
Dust, founded in Paris in 2022 (Dust review), is the closest on this page to Glean's agent side. Admins pick which Slack channels, Drive folders, Notion pages or Confluence spaces an agent may read, and agents can write back to Notion, HubSpot and Salesforce. The platform is model-agnostic across GPT-4, Claude, Gemini, Mistral and Grok, and the EP review states that Doctolib rolled it out to more than 3,000 employees.
The EP review lists SOC 2 Type II, SSO/SAML and SCIM on the Enterprise plan, and EU or US data residency. Dust publishes seat plans and a free tier with credits, unlike Glean. The models behind it are third-party, so a European contracting party does not mean a European model stack, and credit-based usage makes heavy agent work harder to forecast.
What Dust does better than Glean
- Published seat plans and a free tier
- Data residency choice between EU and US stated
- Agents that write back to connected systems
Where Dust is a step down from Glean
- Fewer enterprise connectors and no on-premises index
- Model providers are mostly US labs
- Single-tenant deployment only on Enterprise
Standout against Glean. Combines per-folder access scoping with agents that can update records in the connected systems.
Zeta Alpha
Amsterdam agentic search for research and engineering knowledge
Best for: R&D and engineering groups searching papers, patents, tickets and internal documents together
Zeta Alpha Vector B.V. in Amsterdam builds agentic search and retrieval-augmented generation aimed at research and engineering teams. The cards describe federated search and an optional private tenant. Where Glean aims at every department, Zeta Alpha narrows to people who read technical literature and internal reports side by side.
The price list is short and public at the bottom end: an Open Access plan is free, a Personal AI Assistant costs €20 per month billed annually, and Team and Enterprise are on request. A free trial of the personal plan is available on request. No hosting region was found on the pages read, so data location must be confirmed with the vendor.
What Zeta Alpha does better than Glean
- Published personal plan at €20 per month
- Focus on technical and scientific material
- Dutch company with an optional private tenant
Where Zeta Alpha is a step down from Glean
- Much narrower department coverage than Glean
- Hosting region not stated on the pages read
- Team and Enterprise prices on request
Standout against Glean. The one tool here with a free entry plan and a personal paid plan aimed at individual researchers.
Best for: Engineering teams that want to assemble governed retrieval pipelines and agents themselves
deepset GmbH of Berlin (HRB 197429 B) maintains Haystack, an Apache 2.0 framework with more than 26,000 GitHub stars for retrieval pipelines and agents (deepset review). On top sits a proprietary Enterprise Platform with a visual pipeline builder, role-based access control, audit logs and guardrails, deployable in the cloud or self-hosted. The company holds SOC 2 Type II.
This is a build route against Glean's buy route. The free Studio tier gives one workspace, one user, 100 pipeline hours and 50 files, enough for a prototype. Enterprise pricing is quoted. Customers outside the United States contract with deepset GmbH under German law, while US customers contract with deepset Inc. in New York, so the company is not EU-only in its footprint.
What deepset does better than Glean
- Open-source core you can read, fork and self-host
- German contracting party with Berlin courts outside the US
- Full control over retrieval, routing and guardrails
Where deepset is a step down from Glean
- Needs developers; no ready connector library for staff to click through
- Free tier is a prototype limit
- Also has a US entity and office
Standout against Glean. The only open-source framework on this page, with a self-hosted enterprise platform above it.
What actually breaks when you switch
The first thing that breaks is the connector setup. Expect each source to be re-authorised and re-indexed in the new product, since connector setups and crawl scopes are specific to each vendor.
Plan for a parallel run: keep Glean active while the new index is built and tested on your five or six most-searched systems, and cut over team by team. The index itself is not the loss, because it is rebuilt from the sources, but anything your staff built inside Glean, such as agents or saved prompts, should be inventoried early and checked for an export route, since a new product will not import it by itself.
The second break is the user habit. Staff who ask Glean Assistant for status updates or meeting prep will notice differences in tone, speed and source citation, and search-first products may feel older in the interface.
Budget for training, an internal champion per department, and a feedback channel for wrong answers in the first month. Contracts matter too: check the notice period, the data-deletion terms for your index, and any committed spend before you announce a switch, because a short transition period forces the parallel run to be cut shorter than you want.
Can a European vendor match Glean on connectors and permissions?
On raw count, one can: Mindbreeze names 500-plus data sources and says existing permissions are preserved, with authorisation computed ahead of time from referenced access control lists.
Sinequa states 200-plus native connectors and 350 document formats, and IntraFind lists 80-plus connectors with continuous rights checks. Glean lists more than 250 and says answers respect what a user may see. The count matters less than whether your three or four core systems are on the list and whether permission changes reach the index quickly.
The test is simple. Pick five documents with different sharing settings, include one that was shared last week and unshared this morning, and ask each shortlisted vendor to run it on a trial index. Vendors rarely publish how fast a changed permission propagates, and this is the one fact a demo will not volunteer.
Is leaving Glean mainly a legal decision or a product decision?
It is usually both, in that order. The legal trigger is a contract and a jurisdiction: a US controller, US processing named in the privacy statement, and data-transfer mechanisms that you have to document. If your data protection officer or a public-sector tender rules that out, the product comparison only starts among European vendors. If nobody objects to the US contract, the better argument is price transparency and deployment choice.
The product decision then depends on size. A company with a few hundred staff and Slack, Notion and Drive as main sources can try Langdock, Dust or Ayfie within days. An organisation with SAP, document management and file shares from the nineties should shortlist Sinequa, Mindbreeze or IntraFind and plan a project of months rather than weeks.
Which one to pick
If you want an assistant quickly and need a stated price, start with Langdock or Ayfie, and look at Dust when your agents must act on CRM or Notion data. If the buying criterion is the number of systems and the strength of permission handling, shortlist Mindbreeze and Sinequa first, with IntraFind as the German option that also runs on your own servers.
If your rule is that nothing may leave your network, Squirro, Intergator, IntraFind and LightOn are the ones to test. Choose Zeta Alpha for research-heavy teams and deepset only when you have developers who would rather own the pipeline than rent a product. Keep Glean if broad connector coverage, many model choices and a global enterprise roster outweigh the jurisdiction issue for you, since no vendor here matches all of that at once.
Frequently Asked Questions
It depends on what you use Glean for. For an assistant over cloud tools, Langdock, Dust and Ayfie are the closest in spirit, and Langdock and Ayfie publish prices.
For enterprise search across many internal systems, Mindbreeze, Sinequa and IntraFind are the established platforms, and Squirro and Intergator suit installations inside your own network. LightOn, Zeta Alpha and deepset fit narrower cases: sovereign document estates, research teams, and developers building their own retrieval. Test two on your own content before choosing.
The pages read for this comparison do not say. The privacy statement covers the website and business operations, states that personal information may be transferred to and processed in the United States, and describes Standard Contractual Clauses and Data Privacy Framework certification as the safeguards. Product data location is a contract matter. Ask Glean for the region, the sub-processors and the support-access rules in writing before you decide anything.
Glean does not publish prices; its pricing URL leads back to the home page and the site offers a demo request. European comparisons are easier where vendors publish: Langdock lists €25 per Standard seat per month excluding VAT, Ayfie lists €2,000 a month for the Index plus €15 to €20 per assistant user, and Zeta Alpha lists €20 per month for its personal plan. IntraFind, Mindbreeze, Sinequa, Squirro, Intergator and LightOn quote on request, so you compare them by offer.
Several European vendors say so on their own sites. IntraFind offers on-premises, hybrid or cloud, Squirro describes full on-premises and air-gapped delivery, Intergator lists on-premises or private cloud, Ayfie adds private cloud with local model hosting, and LightOn runs Paradigm on-premises or in a private cloud. The pages read for Glean describe no on-premises option, so a requirement of that kind rules it out unless the vendor confirms otherwise in writing.
It is safe if the vendor passes your own checks, and that is where small and large differ. Ask for a company register extract, the hosting arrangement, a security certificate or audit report, and a reference at your size.
Some vendors here are small: LightOn reported annual recurring revenue of 1.9 million euros at the end of 2025 according to the EP review, while Sinequa sits inside the ChapsVision group and Mindbreeze inside Fabasoft. Continuity risk differs per vendor, so weigh it explicitly.
