Medium Launches TK App to Integrate AI Directly into Writing Process with Transparency Focus

Online publishing platform Medium launched a new app called TK on Monday, aiming to bring artificial intelligence deeper into the writing process. The core idea is to make it easier to turn ideas into written words by incorporating an AI assistant directly into the editor itself. Users can ask for help by typing “@TK” followed by their request or prompt.

In publishing and journalism, “TK” traditionally serves as a placeholder for missing information (To Come). Medium gives this term a new meaning, using the AI assistant to help users fill in the blanks. According to TechCrunch, TK can answer questions that would normally require switching tabs to look up, such as the number of days in a particular month, and can pull in bits of writing previously saved to the app during ideation. Additionally, TK ships with skills for editorial feedback, headline feedback, and matching drafts to the style guide for Medium publications.

This move comes at a time when the publishing and literary worlds are reckoning with the role AI has played in creating new long-form prose. Multiple authors have lost book deals over suspicions of using AI technology, while other literary awards have come under scrutiny after winners were suspected of writing with AI assistance. While writers have long used automated tools for proofreading and light grammatical edits, there is growing concern across the industry that an AI assistant’s editorial “suggestions” can become the writing itself, instead of reflecting the writer’s own thoughts.

Medium leans into this debate, taking the side that these nuances will ultimately no longer matter. The company celebrates what AI can bring to writing, stating in a blog post that “artificial intelligence makes writing more important, not less,” and proclaiming that “AI is a technology that has the power to amplify human intelligence and it uses the written word as a foundation.” To address concerns about low-quality content and blurring the line between human-written and AI-written text, TK allows authors to publish notes that transparently explain how AI was used in their writing. Medium explained that 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.”
