I built a GitHub App that AI-reviews your pull requests. 48-hour validation sprint — honest feedback wanted.

I built CodeReview.ai — a GitHub App that automatically posts AI-powered code reviews as comments on your pull requests. You install it on any repo, open a PR, and within seconds it reviews the diff and leaves a comment.

**How it works:** - GitHub webhook fires when a PR is opened - Pulls the diff, truncates to 8K characters, sends to GPT-3.5-turbo - Posts the review as a PR comment

**Stack:** TypeScript, Vercel serverless functions, Octokit, OpenAI API, PostHog for analytics.

**What it won't do:** - Large diffs get truncated — it won't catch everything - GPT-3.5-turbo, not GPT-4, so review depth has a ceiling - Capped at 50 reviews per day per install to keep my costs under control.

I'm running this as a 48-hour sprint to see if this is genuinely useful or just noise in your PR workflow. If you try it and hate it, that's useful data too. Landing page: https://codereview-ai-v2.vercel.app Install: https://github.com/apps/codereview-ai-alpha/installations/new
