What TextCortex actually does
TextCortex is an AI writing and knowledge assistant built around the idea that most useful AI work isn't a single chat window — it's an agent that already knows your company's documents, your writing style, and your recurring tasks. The company, headquartered in Berlin, calls its assistant "Zeno" and structures the product around three pillars: searching and answering questions from your own organizational data (Company Knowledge), automating repetitive writing and formatting tasks (Workflow Automation), and building, deploying and managing custom AI agents for specific jobs (Enterprise Agents). It was seeded with $1.2M in pre-seed funding from btov Partners, Speedinvest and Entrepreneur First, and the company reports 2.4 million users worldwide.
The core product
Day to day, most users interact with TextCortex through its Chrome browser extension, which drops an AI writing assistant into any text field across the web — email, LinkedIn, CRM notes, support tickets — plus a native desktop app for Windows and macOS and a standalone web dashboard. On top of straightforward AI writing (rewriting, summarizing, translating, generating from a prompt), the platform layers Knowledge Bases: you upload files or connect Google Workspace/Microsoft 365, and the AI can then answer questions or draft content grounded in those specific documents rather than generic training data. Custom "Agent Skills" and connectors let teams build repeatable automations — for example, an agent that drafts a specific type of client email using your actual templates and past correspondence.
What's new or notable
The most distinctive thing about TextCortex in 2026 is its privacy posture relative to competitors: the company holds both SOC 2 and ISO 27001 certifications, runs on EU-hosted infrastructure, and states explicitly that none of your data is ever used to train underlying models. For a category where "we use your data to improve our AI" is a common (if buried) clause, an explicit no-training commitment paired with formal certifications is a genuine differentiator, especially for regulated or security-conscious European teams evaluating AI writing tools.
Who should use TextCortex
Great fit if…
- You want AI grounded in your own documents — the Knowledge Base and connector features are built for exactly this, rather than treating every query as a blank-slate prompt.
- Data handling policy is a deciding factor — SOC 2, ISO 27001, EU hosting and a no-training guarantee are unusually concrete commitments for this category.
- Your team needs repeatable AI workflows, not just one-off writing help — custom agents and skills are designed for recurring tasks.
Skip it if…
- You just want occasional help drafting an email — the free plan is thin, and Premium's per-seat price is steep for light, occasional use compared to simpler writing tools.
- You want zero setup — getting value from Knowledge Bases and custom agents requires uploading documents and configuring connectors, not just typing a prompt.
Pricing in detail
Checked live from an EU browsing session on 2026-09-05, TextCortex's own pricing page bills natively in euros. The Free plan costs €0, requires no credit card, and includes access to Knowledge Bases with up to 50 MB of file storage, custom agent creation, Agent Skills and Connectors, and Deep Research — but with limited underlying model usage, making it more of a guided trial than a sustainable free tier. The Premium plan is €23.99 per user per month, VAT excluded, billed annually (2 months free versus paying month to month), and adds access to all major AI models with included usage, up to 10 GB of file storage, and image generation. Enterprise pricing is custom and adds SSO/SCIM/SAML authentication, dedicated deployment, centralized billing and priority support.
| Plan | Price | What's included |
|---|---|---|
| Free | €0 | Knowledge Bases (50 MB storage), custom agents, Agent Skills/Connectors, Deep Research, limited model usage |
| Premium | €23.99/user/month (excl. VAT, billed annually) | All major AI models, included usage, 10 GB storage, image generation |
| Enterprise | Custom | SSO/SCIM/SAML, dedicated deployment, centralized billing, priority support |
Where it falls short
- Free plan is a demo, not a daily tool — 50 MB of storage and capped model usage push serious users toward Premium quickly.
- Premium is priced like enterprise software — roughly €24/user/month (plus VAT) is high for an individual freelancer compared to lighter single-purpose writing tools.
- Annual billing required for the headline rate — the pricing page defaults to the annual "2 months free" toggle, so confirm the monthly-billed rate before assuming the headline price applies.
Privacy & data
TextCortex is the strongest privacy story among this batch: the company states plainly that none of your data is used to train its models, runs on EU-hosted infrastructure, and holds both SOC 2 and ISO 27001 certification — third-party-audited standards rather than self-declared claims. As a Berlin-headquartered company it is directly subject to German and EU data protection law (GDPR).

What you get, what you give up
What you get
- A genuine no-training-on-user-data policy paired with SOC 2 and ISO 27001 certification and EU-hosted infrastructure — a stronger, more specific privacy commitment than most AI writing assistants publish.
- Custom agent and knowledge-base building (Knowledge Bases, Agent Skills, Connectors) rather than a single fixed chatbot, letting teams point the AI at their own files and internal documentation.
What you give up
- The free plan's value is mostly in exploring the interface: file storage is capped at 50 MB and there's no meaningful volume of premium AI model usage included, so it functions as a demo more than a usable daily tool.
- Premium's per-seat price applies on top of VAT, and the discounted rate shown requires annual billing rather than paying month to month.
