Medium launches TK, a writing app with an in-editor AI assistant
Medium launched TK, a free writing app for users with a Medium account, on 2026-11-09. Its main feature is an AI assistant built into the editor, invoked by typing "@TK" followed by a request. The assistant can answer quick factual questions, pull in previously saved drafts, and offer editorial, headline and style-guide feedback. TK also lets authors publish notes that explain how AI was used in a piece, and it can connect to a user's own AI agent through an MCP server or Claude skill. This is product and business news with no reported vulnerability, exploitation or breach. The only security-relevant points are that TK's writing is not encrypted, by design for collaboration, and that users can set access-control permissions on their work.
