Jit (short for Journal-IT) is a developer productivity tool that automatically generates a detailed journal of your GitHub activity — including commits, pull requests, and issues — using the power of the Gemini API and the GitHub API.
With a single click, developers can turn their daily contributions into structured, insightful journal entries — and publish them as a personal webpage using GitHub Pages.
