TextCortex is an enterprise-focused generative AI platform that combines AI writing assistance with powerful knowledge management and search. Originating as an AI writing assistant, it has evolved into an "enterprise agent infrastructure" that helps organizations connect internal and external knowledge, build custom AI agents, and bring AI directly into the apps and websites where employees already work. With a browser extension, desktop app and web interface, TextCortex supports content creation, research, data analysis and multilingual communication from virtually any text box.
Founded in 2021 and headquartered in Berlin, Germany, TextCortex is backed by leading European VCs including b2venture, Speedinvest and Entrepreneur First and has raised a $1.2M pre-seed round to date. The company has been recognized as one of the top 200 generative AI startups in Europe and has been featured in G2’s Top 10 Best AI Software Products, with consistently high user satisfaction scores across G2 and Capterra. According to its own data, TextCortex serves more than 2.4 million users worldwide and reports strong adoption in deployments with 100+ seats.
The core of the platform is a model-agnostic agent infrastructure and model hub. Organizations can connect leading LLMs such as GPT, Claude, Gemini, Mistral and others, avoid vendor lock-in, and configure which models power which use cases. Knowledge bases aggregate content from file systems, SharePoint sites, cloud drives, wikis and the public web so that AI agents can answer questions with context, provide citations, and support workflows like proposal writing, customer support, research and internal knowledge search.
TextCortex differentiates itself with a strong emphasis on European data sovereignty and enterprise security. The platform is hosted in the EU, is GDPR compliant, and is certified for SOC 2 and ISO 27001. Its positioning targets mid-market and enterprise organizations—especially in Europe—that need customizable AI agents, deep integrations with existing knowledge sources, and strict governance, while still retaining the familiar strengths of a modern AI writing and content creation assistant.
