Show HN: AI PR reviewer built to stay quiet – 89% of merged PRs got no comments

PR-Sage, an open-source AI-powered pull-request reviewer, launched publicly on August 19, 2026, per a Show HN post by author gudrua1543. The tool's headline claim: 89% of merged pull requests received no comments from it, positioning low-noise review as the core design goal.

The project is hosted on GitHub and appears to be an independently developed utility rather than a commercial product at launch. No pricing, team size, or funding details are disclosed in the source material.

PR-Sage is built to integrate into existing code review workflows as an automated reviewer that flags only what it deems genuinely worth flagging. The 89% silence rate is framed as a feature rather than a gap — the premise being that most AI code review tools generate too much noise, causing developers to ignore automated feedback altogether.

The broader context is a crowded field of AI code review tools, including established players such as GitHub Copilot's review suggestions and a range of third-party bots. The recurring complaint in that space is alert fatigue: automated reviewers that comment on every minor style issue or produce false positives train developers to dismiss their output. PR-Sage's positioning targets that specific pain point directly.

The HN submission had one point and no comments at the time of publication, so independent developer reaction is not yet available. No roadmap, expansion plans, or contributor details are mentioned in the source material.
