What changed
Medium has launched a new app called TK, which integrates AI assistance directly into the writing process. The app allows users to ask for help by typing “” followed by their request or prompt. The AI assistant can answer questions, pull in previously saved writing, and provide editorial feedback, headline suggestions, and style guide alignment. TK also allows users to publish notes explaining how AI was used in their writing, aiming for transparency in the AI era.
What this means in practice
The TK app is designed to assist writers by making the writing process more efficient. It can help with tasks like answering factual questions, recalling previously saved content, and offering editorial suggestions. The app also includes a social layer for sharing early drafts and receiving feedback. TK is available on the web, with a desktop version planned for the future. It supports Markdown import and export but is not a Markdown app itself. The app is free for Medium account holders and does not encrypt writing, though access control permissions can be set.
Limitations and availability
TK is currently available on the web, with a desktop app in development. The app does not encrypt writing, as it is designed for collaboration. While it can connect to external AI agents through its MCP server or Claude skill, this is optional. The app does not replace human writing but aims to enhance it. Medium acknowledges concerns about low-quality content and the blurring of human versus AI-written work, but emphasizes the importance of transparency in the AI era.
