Medium is launching TK, a notes, journaling, and private-sharing app, CEO Tony Stubblebine told The Verge on Monday, calling it the company’s first major product launch since 2017¹.

The app, at tk.xyz, is meant to combine spare note-taking with longer writing and sharing that does not depend on search traffic, David Pierce reported¹.

Stubblebine said Medium’s last important launch was in 2017, when then-CEO Ev Williams shifted the site away from advertising toward subscriptions¹.

He told Pierce that declining Google referrals are an existential risk for sites like Medium, and that the company’s roadmap is to move writing into private spaces¹.

TK is a minimal note-taking app focused on daily journal-style notes and longer pieces¹. Users can point an AI model at their writing to search notes, organize them, or request feedback¹. Typing the letters “TK,” a writers’ placeholder, summons the model to fill in information, Stubblebine said¹.

Writing can be shared by link or email, with collaborators able to edit, comment, and leave emoji reactions¹. Users can also add work to Libraries, which Stubblebine described as private blogs for a topic or group, with no public face and membership ranging from a few people to a few hundred¹.

“Medium is, at some level, performative,” Stubblebine said, adding that TK is not built around pageviews or being noticed¹.

TK is available to existing Medium members on the web, Android, and iOS, with a native desktop app planned, Stubblebine said¹. He said similar features are coming to Medium later, and floated charging people or AI agents for packaged library content as a possible business path¹.
