TextCortex
AI writing assistant with 30,000+ platform integrations for everywhere you work
About TextCortex
TextCortex is a versatile AI writing and content creation platform that embeds intelligent writing assistance directly into over 30,000 websites and applications through its browser extension, eliminating the need to switch between tools or copy-paste between platforms. Founded with the vision of making AI writing assistance ubiquitous and context-aware, TextCortex has evolved from a simple text generation tool into a comprehensive AI co-pilot that adapts to each user's writing style, tone, and specific needs across email clients, document editors, social media platforms, content management systems, and virtually any text input field on the web. The platform supports over 25 languages and processes billions of characters monthly for users ranging from freelance writers and marketing professionals to enterprise teams managing customer communications at scale.
What sets TextCortex apart in 2025 is its dual approach of providing both a standalone web app and seamless in-context assistance through browser and desktop extensions for Chrome, Edge, Firefox, Safari, and dedicated desktop apps for Windows and macOS. This enables users to invoke AI writing help with simple keyboard shortcuts (Cmd/Ctrl + Shift + K) regardless of their current application, whether composing LinkedIn posts, drafting sales emails in Gmail, writing documentation in Notion, or responding to customer tickets in Zendesk. The platform leverages multiple AI models including GPT-4, Claude, and proprietary models optimized for specific writing tasks, with the Zeno Assistant acting as an intelligent orchestration layer that selects the optimal model based on the task at hand. Features include tone adjustment, content expansion and summarization, rewriting for clarity, translation across 25+ languages, and custom prompt templates called "ZenoChat" for recurring writing patterns.
TextCortex offers a generous freemium model starting with 100 free daily creations for new users, allowing substantial testing before commitment. The Lite plan ($5.59/month when billed annually) provides 100 creations daily with GPT-4o access, while the Unlimited plan ($83.99/month annually) offers unlimited AI generations, priority support, advanced customization, and team features. Enterprise customers receive custom pricing with dedicated infrastructure, API access, SSO, advanced security controls, and white-labeling options. The creation-based model rather than character limits provides more predictable usage for professional writers who generate varied content lengths.
The platform has found strong product-market fit among content marketing teams managing multiple channels, sales development representatives personalizing outreach at scale, customer support agents responding to inquiries more efficiently, and multilingual businesses requiring consistent tone across language translations. TextCortex's ability to maintain context and adapt to user corrections over time creates an increasingly personalized AI assistant that understands industry jargon, brand voice, and individual writing preferences, making it particularly valuable for professionals who write extensively as part of their daily workflows across diverse platforms.
