TextCortex
AI writing assistant that lives in your browser — paraphrase, create, and chat anywhere.
About
TextCortex is an AI writing assistant built around a Chrome extension that works across 30+ platforms — Gmail, Notion, LinkedIn, Google Docs — plus a web app with ZenoChat (conversational AI), a note editor, and knowledge bases you can feed with Google Drive, Notion, and Dropbox documents. Standout features include Zeno Mode for long-form drafting, bulk paraphrasing, 20+ writing templates, 72+ supported languages, and the ability to switch between frontier models (Claude, Gemini, DeepSeek R1). The Creator Suite targets marketers and teams with brand voices and collaboration.
The honest picture: the free plan is genuinely limited (around 10–20 daily creations), and serious use pushes you to paid tiers up to an $83.99/month unlimited plan. Quality varies by chosen model and task — it's a generalist, not a specialist editor like ProWritingAid. There's no offline mode, no real mobile app experience, and pricing details shift often enough that you should check current plans before committing.
