PRobe

AI review companion for GitHub PRs

AI-powered code review sidekick, right inside GitHub pull requests. You're reviewing a pull request. You have questions. Why was this function rewritten? Does this handle the edge case? Are these changes across two files actually consistent? The developer isn't next to you right now, and the PR description is alphabet soup. PRobe fills that seat. It's an AI sidekick that lives inside every GitHub PR page, ready to answer your questions grounded in the actual code — the diff, full file contents, commits, reviews, linked issues, and CI status. No copy-pasting into a separate chat window. No leaving the page. 𝗖𝗛𝗔𝗧 𝗪𝗜𝗧𝗛 𝗧𝗛𝗘 𝗣𝗥 Open the side panel and ask anything. PRobe sees the full diff, title, description, commit history, and reviewer discussion. Ask why something changed, whether an edge case is handled, or if two changes in different files are consistent. Get answers rooted in what actually happened, not guesses. 𝗭𝗢𝗢𝗠 𝗜𝗡𝗧𝗢 𝗙𝗜𝗟𝗘𝗦 𝗢𝗥 𝗟𝗜𝗡𝗘𝗦 Click any changed file to scope the conversation and load the full file content — not just the diff hunks. Select specific lines through GitHub's comment UI to discuss an exact code region. Pin up to 3 files or line ranges at once for cross-cutting questions. 𝗙𝗢𝗖𝗨𝗦 𝗢𝗡 𝗧𝗛𝗘 𝗟𝗢𝗚𝗜𝗖, 𝗡𝗢𝗧 𝗧𝗛𝗘 𝗟𝗜𝗡𝗧 PRobe automatically detects the tech stack in the diff and loads built-in review guidelines — React patterns, Python best practices, API design principles, and more. It catches everything from missing imports to subtle edge cases and cites specific rules, so you can spend your review time on architecture and intent. 𝗣𝗥 𝗗𝗔𝗦𝗛𝗕𝗢𝗔𝗥𝗗 When you open the panel, see additions, deletions, commits, reviewers, and the most-changed files at a glance — plus AI-generated focus prompts so you know where to start. 𝗣𝗢𝗦𝗧 𝗖𝗢𝗠𝗠𝗘𝗡𝗧𝗦 𝗔𝗡𝗗 𝗦𝗨𝗕𝗠𝗜𝗧 𝗥𝗘𝗩𝗜𝗘𝗪𝗦 Turn any AI response into a GitHub comment with one click. Collect inline comments into a review queue and submit them as a single review: Comment, Approve, or Request Changes. Never leave the page. 𝗙𝗥𝗘𝗘 𝗔𝗡𝗗 𝗢𝗣𝗘𝗡 𝗦𝗢𝗨𝗥𝗖𝗘 PRobe is free, open source (AGPL-3.0), and uses your own Anthropic API key. No account to create, no subscription, no data stored on external servers. Add a GitHub token to unlock comment posting. Everything stays in your browser. 𝗕𝗨𝗜𝗟𝗧 𝗙𝗢𝗥 𝗗𝗘𝗩𝗘𝗟𝗢𝗣𝗘𝗥𝗦 X-Ray mode lets you inspect the full system prompt the AI receives — every instruction, every piece of context, every guideline that was loaded. Intelligent suggested prompts adapt to what you're looking at. You always know what the AI sees and you're always in control. Learn more at https://getprobe.dev
