Medium launches TK, a note-taking app with private sharing
Medium is launching TK, a note-taking and journaling app that also offers ways to share writing.
The app lets users ask an AI model to search or organize their notes, give feedback, or help fill in information.
People can share writing through links or email, where others can comment, collaborate and react.
They can also contribute to topic-based Libraries, which Medium describes as private blogs without a public-facing page.
Medium moved to a subscription model in 2017, turning away from advertising as its main business.
The company says declining Google referrals threaten websites like Medium, while AI companies are collecting online content.
TK is part of Medium’s effort to build a writing network less dependent on search traffic.
Medium launched TK, an app combining note-taking and journaling with AI writing assistance and private sharing.
Users can ask an AI assistant for help in the editor by typing “@TK” followed by a request.
The app can help organize and search saved writing, offer feedback, and suggest prompts.
Users can share writing through links or email, invite collaborators to comment, and contribute to topic-based Libraries.
Medium says authors can disclose how AI was used, amid concerns that AI assistance may blur the line between human- and AI-written work.

What people are saying
I don’t think we’ve actually had a launch of anything important since 2017
artificial intelligence makes writing more important, not less
AI is a technology that has the power to amplify human intelligence and it uses the written word as a foundation.
This is 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
