What is TextCortex?

TextCortex is an AI writing platform built around ZenoChat, a customizable AI assistant that lives in your browser, desktop, and mobile devices. TextCortex differentiates itself with Personas, letting you create multiple AI assistants each trained on different writing styles, brands, or domains. The TextCortex Knowledge Bases feature ingests your documents and websites so ZenoChat can answer questions and write with your specific data in mind. TextCortex works across 30+ languages and 4,000+ web apps via its browser extension, bringing rewriting, summarization, and AI generation to wherever you write. With access to GPT-4, Claude, and proprietary Sophos models, TextCortex offers strong AI flexibility at a competitive price point for individuals and teams.
