TextCortex is an AI writing and productivity platform that embeds generative AI directly into the tools people already use, via a browser extension, desktop app, mobile app, and API, rather than requiring users to switch to a separate chat window. It focuses on practical business writing tasks: emails, product descriptions, social posts, summaries, and translations.
Founded in 2021 in Berlin, Germany, TextCortex has grown into a team of roughly 20 to 25 people and has been recognized among notable early-stage European AI startups. The platform emphasizes customization through AI personas and connectable knowledge bases, letting outputs reflect a company's specific tone, products, and internal documentation.
TextCortex offers AI-powered writing, rewriting, translation, and summarization across a browser extension, desktop app, and API, alongside more than 500 prompt templates for tasks such as email replies, LinkedIn posts, and product listings. Customizable personas let users tailor tone and style for different use cases or brands.
The platform also supports connectable knowledge bases so generated content can be grounded in company-specific documents rather than generic web knowledge, plus built-in AI web search and, on paid plans, image generation and access to more advanced reasoning models.
TextCortex offers a free plan with 20 daily creations, up to three personas, three knowledge bases, and 50MB of file storage. The Premium plan starts at roughly 5.59 dollars per month billed annually (6.99 dollars per month billed monthly) and includes 150 monthly creations, 100MB of storage (upgradable to 100GB), access to reasoning models, full tool access, and image generation. An Enterprise plan with custom pricing adds single sign-on, governance features, and priority support.
