Medium launches TK writing app with integrated AI assistant
Medium launched a new web app called TK that embeds an AI assistant directly into its editor, invoked via “@TK”, to help users draft, retrieve saved notes, give editorial and headline feedback, and match publication style. The company says TK can optionally connect to a user’s agent via TK’s MCP server or a Claude skill, will let authors publish notes on AI usage for provenance, supports Markdown import/export, and is free for Medium account holders.
