The tool's marketing claims it is lightweight and token-efficient, keeps private diffs on the user's own infrastructure so \"your PRs never become someone else's training set,\" and posts line-numbered comments on code such as a duplicated session check and a swallowed Stripe charge error. The project positions itself as a self-hostable alternative for teams that want automated diff review without sending code to a third-party vendor.", "body_md": "pr #418 quick auth fix 🙏\n\ndenied\n\n```\n@@ checkSession @@\n if (!session) throw new Error(\"nope\")\n if (!session) return true // trust the vibes\n```\n\nAI that reviews GitHub PRs like the coworker who actually reads the diff — then leaves comments you’ll think about in the shower.
