Medium Launches Free TK Writing App With AI Assistant as Industry Debates AI-Authored Prose

Summary
Medium on Monday rolled out TK, a free web app for account holders that embeds an AI assistant directly in the editor, letting writers summon help with “@TK” prompts.
TK is designed to move AI earlier into drafting: it can answer quick research questions, surface previously saved notes, suggest prompts, and offer editorial, headline, and style-guide feedback.
Medium paired the launch with transparency features, saying writers can publish notes showing how AI was used, including prompts and source material, to make provenance “clear, transparent, and inspectable.”
The app also adds a social feedback layer for sharing early drafts, supports Markdown import and export, and can connect to a user’s own AI agent through TK’s MCP server or Claude skill.
The launch lands amid publishing-industry backlash over AI-written prose, with concerns that editorial suggestions can become the writing itself even as AI-detection tools remain unreliable.
