Medium’s new TK app brings AI assistance directly into the writing process
Medium launched TK, an AI-powered writing app that integrates an assistant into the editor to help turn ideas into written words.Summary
Medium has launched a new app called TK that integrates an AI assistant directly into the writing process. Users can invoke the assistant by typing “@TK” followed by a request, enabling it to answer quick questions, pull in previously saved writing fragments, and provide editorial and headline feedback. The app also offers features to help organize past writing, suggest prompts, and optionally connect to external AI agents via an MCP server or Claude skill. It includes a social layer for sharing drafts and receiving human feedback. While Medium embraces AI as a tool to amplify human intelligence, it acknowledges concerns about low-quality content and the blurring of human versus AI writing. To address this, TK allows authors to publish transparency notes explaining how AI was used, aiming to make the provenance of writing clear and inspectable. TK is available on the web for free to Medium account holders, with a desktop app planned.
