DEON

DEON is a zoomable visual workspace from DEON GmbH & Co. KG in Berlin.

DEON goes beyond sticky notes: projects can hold documents, video files, live sources and embedded web browsers, and the site lists use cases from brainstorming and workshops to shopfloor management and personal dashboards. DEON now positions itself as an AI workspace, with a graph chat view and connections to AI endpoints including OpenAI, Microsoft Copilot and Google Gemini. Besides the web client, DEON provides installable applications for Windows, macOS and iOS, and its plans mention a REST API.

DEON GmbH & Co. KG is registered at Amtsgericht Charlottenburg under HRA 44827 B, and its terms are governed by German law with Berlin as the place of jurisdiction for business customers.

DEON reports a TISAX assessment under the VDA ISA catalogue, audited by DEKRA Certification GmbH and operational services GmbH & Co. KG. The privacy policy states that project data is stored encrypted in Microsoft Azure West Europe through Microsoft Ireland Operations Ltd., and that OpenAI and Google are used for optional AI functions under standard contractual clauses.

DEON Free covers 2 own projects with 100 elements per project and 20 MB per element. DEON Premium costs EUR 10 per month excluding VAT and removes the project and element limits.

DEON Corporate adds corporate branding, organisation-wide templates, an admin interface and a choice of public cloud, dedicated cloud or self-hosting, at a price on request. DEON is a fit for automotive suppliers and authorities that need the TISAX label or an isolated installation. Teams looking for a light browser whiteboard with a European cloud underneath will find DEON heavier than needed and tied to Azure in its hosted form.

What DEON does well

• DEON has completed a TISAX assessment under the VDA ISA catalogue, audited by DEKRA Certification GmbH.
• The DEON terms describe a fully isolated on-premises installation for customers that need maximum data sovereignty.
• DEON offers installable clients for Windows, macOS and iOS next to its web client.
• DEON Premium is published at EUR 10 per month with unlimited projects and elements.
• DEON stores hosted project data in the EU, in the Microsoft Azure West Europe region.

Where DEON falls short

• The hosted DEON service runs on Microsoft Azure rather than on a European-owned cloud.
• DEON Corporate, which holds the on-premise and dedicated cloud options, has no published price.
• The optional AI functions of DEON involve OpenAI and Google as US-based processors.
• The free DEON plan is limited to 2 projects with 100 elements each.

Standout feature. DEON is the only tool in this list with a TISAX assessment, which makes it the natural candidate where automotive information security rules decide the purchase.
