Medium on November 4 introduced TK, a new app that embeds an AI assistant directly into its writing editor. Users can invoke the assistant by typing “@TK” followed by a prompt, allowing the tool to answer quick factual questions, surface previously saved text, or suggest prompts and organization for drafts.
How TK works inside the editor
The name TK is drawn from the publishing placeholder “to come.” Medium describes TK as a tool that can provide editorial feedback, headline feedback, and other skills that may help align a draft with a publication’s style guide. The app can import and export Markdown, though Medium says TK is not itself a Markdown app.
TK can optionally connect to a user’s own AI agent via TK’s MCP server or a Claude skill so the app can reference project context stored in an agent’s memory. The writing within TK is not encrypted because the product is built for collaboration, but users can set access control permissions on their work. At launch TK is available on the web; a desktop app is on the roadmap. Medium says TK will be a free tool for anyone with a Medium account.
Publishing concerns and provenance
Medium acknowledged that integrating AI into early stages of writing intersects with ongoing debates in the publishing and literary worlds. The industry has seen authors lose book deals amid suspicions of AI use and scrutiny of awards where winners were suspected of using AI assistance. Publishers and many authors express concern that editorial suggestions from AI could become the writing itself rather than reflecting the author’s original ideas.
To address transparency, TK allows authors to publish notes explaining how AI was used in their pieces. Medium framed this as “a start of what we believe is required to publish in the AI era, which is to make the provenance of writing clear, transparent, and inspectable, right down to the prompting and source material.” The company also stated that “artificial intelligence makes writing more important, not less” and described AI as a technology that can “amplify human intelligence.”
At launch, TK supports sharing drafts for human feedback and aims to help writers remember and organize earlier work. Medium says the app will remain free for account holders and will evolve with additional platform features.
