Problem
Pull request descriptions are vague, strenuous, and time-consuming to write. Developers waste time context-switching from coding to prose-writing after every commit, producing inconsistent, low-quality PR descriptions. Poor descriptions lack structure (What / Why / How to Test), slowing down code review and increasing PR cycle time.
Solution
A zero-login, browser-based tool where developers paste a git diff and instantly receive a structured, editable PR description. Output follows a consistent schema (What Changed / Why / How to Test / Notes) and can be copied to clipboard in one click — no backend required.
User flow
- Paste a git diff into the browser tool
- The LLM extracts developer intent from raw line changes
- A structured PR description is generated (What / Why / How to Test / Notes)
- Edit if needed and copy to clipboard in one click
LLM components
- Semantic diff parsing — extracts developer intent from raw line changes
- Structured generation with constraint — fixed schema, infers breaking changes, avoids hallucinating test commands not present in the diff
