Medium launched TK, a web app with an AI assistant embedded in its editor. Users can request help by typing “@TK” followed by a question or prompt. Medium says TK offers editorial and headline feedback, can match drafts to Medium publication style guides, and can include notes explaining how AI was used, including prompts and source material. The app also supports a social layer for sharing early drafts and receiving feedback, optional connections to personal AI agents through an MCP server or Claude skill, and Markdown import and export. The Verge describes TK more broadly as a minimalist note-taking, journaling, and private social-networking app with daily prompts. It is available on the web, while a desktop app is on Medium’s roadmap.
A free, two-part Medium series surveys current practices for evaluating Intelligent Document Processing (IDP), with a focus on Key Information Extraction from structured documents, especially forms. According to the author, it covers raw extraction outcomes, confusion-matrix scoring for text fields and checkboxes, treatment of blanks and unreadable values, F1, recall, accuracy, IoU, precision, specificity, calibration, OCR metrics, and the distinction between confidence and correctness. The first part is titled “Confidence Is Not Correctness,” while the second covers approaches to evaluating form extraction.

Teams building small and medium-sized applications often need to assemble authentication, authorization, routing, menus, code generation, file handling, and other common application capabilities before focusing on business development. This project provides those foundations in a Vue and Gin architecture so developers can concentrate on project-specific features.
