TextCortex

TextCortex is an AI writing platform with an enterprise knowledge base attached, and the second half is what distinguishes it. Generic AI writing produces generic text because the model knows nothing about your products, your policies or the way your company describes what it does. Connect a knowledge base and the output starts from your material rather than from the internet's average.

That shifts what it is useful for: not blog posts about a subject, but the internal and customer-facing writing where being wrong about your own product is the failure mode. It works across the applications people already write in rather than as a destination site, which is what keeps it in the workflow instead of beside it.

TextCortex AI was founded in Berlin in 2021 and is explicitly EU-hosted and GDPR-compliant, with enterprise customers including Siemens and Lamborghini — which for a young company is meaningful, since those procurement processes examine data handling rather than accepting a claim. Free tier with paid and enterprise plans above. The underlying models are third-party rather than European, and as with every writing assistant the output still needs an editor before it ships.

What TextCortex does well

• Enterprise knowledge base grounds output in your own material
• Works inside the applications people already write in
• EU-hosted and GDPR-compliant from a Berlin company
• Free tier with a route up to enterprise
• Enterprise references including Siemens and Lamborghini

Where TextCortex falls short

• Underlying models are third-party, not European
• Knowledge base needs populating to be worth it
• Output still needs editing before publication
• Enterprise features behind the higher tiers

Standout feature. It writes from your documents rather than from the internet's average — which is the difference between useful and generic.
