AI assistant that follows you across 30,000+ apps with your knowledge
Updated
TextCortex is an AI assistant for writing and knowledge work. Its assistant, ZenoChat, lives in a browser extension and follows you across email, Google Docs, LinkedIn, Notion and more than 30,000 other apps, and it can answer from knowledge bases and personas that you set up.
You install the browser extension, upload documents to a knowledge base, and pick or create a persona. The assistant then drafts and rewrites text inside the apps you use, drawing on your knowledge base for answers. The vendor FAQ states that none of your data is used for model training or fine-tuning.
TextCortex is for teams and individuals who write a lot in email, documents and CRMs and want an assistant that knows company information. Enterprise customers can get custom arrangements.
A free plan at $0 per month is listed on the pricing page, with limited access to core features. Paid tiers scale with usage, and Enterprise pricing is custom. See the vendor pricing page for current rates.
QuillBot is a paraphrasing and grammar tool popular with students. Paperpal is an academic writing assistant for researchers. Jenni AI is built for writing essays and papers with citations. TextCortex differs by combining a cross-app browser assistant with company knowledge bases.
