PRobe brings AI chat to GitHub pull requests

Code review is still one of the biggest friction points in developer workflows, and PRobe's in-context AI chat approach is a clean answer to reviewer fatigue.

• –Runs entirely inside GitHub's PR UI as a browser extension — no context switching to an external tool or separate tab
• –Chat-with-diff UX means reviewers can ask "why was this changed?" or "what does this affect?" in natural language rather than hunting through commit history
• –Ability to post comments and submit full reviews from the AI interface closes the loop — it's not just analysis, it's action
• –Open-source and free tier lowers the adoption bar vs. paid competitors like CodeRabbit or GitHub Copilot's PR summaries
• –Early-stage with minimal public traction, but the Chrome extension distribution model means viral spread through dev teams is plausible
