I built an AI priority inbox for GitHub pull requests — and went BYOK instead of running my own AI backend A developer built PR Focus, a Chrome extension that prioritizes GitHub pull requests using AI signals and generates plain-English summaries from diffs. The extension uses a bring-your-own-key (BYOK) model for AI providers like OpenAI, Groq, Mistral, or local Ollama, avoiding the need for a custom AI backend. PR Focus is available as a free tier with basic features and a one-time PRO purchase for AI-powered capabilities. GitHub shows your pull requests in whatever order they happened to be opened — not in the order they actually need your attention. A one-line typo fix and a PR touching authentication code get exactly the same visual weight in your inbox. Multiply that across a dozen open PRs and you spend more time deciding what to look at than actually reviewing. PR Focus is a Chrome extension Manifest V3 that sits on top of GitHub's PR pages. It combines three signals into a single priority queue: Each PR also gets a plain-English summary generated from the actual diff not the title someone wrote at 11pm , and you can generate an approve / request-changes draft review in one click, edit it, and send — without leaving the extension. This was the decision I spent the most time on. Running my own AI backend would have meant: Going BYOK bring your own key — OpenAI, Groq, Mistral, or a local Ollama instance flips both of those: chrome.storage.local . There's no server of mine in the path — PR diffs only ever go to the AI provider you explicitly configure.Free tier: multi-account GitHub switching, PR sorting/export, stale-PR notifications. PRO $9.50 one-time, currently 50% off the $19 regular price : AI summaries, risk scoring, one-click draft reviews, full stats history, AI-based priority sorting. No subscription — pay once, own it. Currently solo-maintained, iterating on feedback from the first wave of GitHub stars and a community-contributed PR that got merged — which, honestly, felt like a bigger validation moment than any launch metric so far. Performance-regression detection and broader language support Python, Go are next on the roadmap.
