Show HN: Stage - putting the human back in control of code review

Stage is a code review tool that, instead of reading a large PR diff all at once, breaks the changes into small chapters to be reviewed in order.

It started from the problem awareness that GitHub's existing review UI is complex, and especially with AI coding agents making PRs even larger, it has become hard for reviewers to understand the overall behavior.

The core behavior is as follows.

• Group the PR's changes into logical units
• Order the chapters in the most readable sequence
• For each chapter, present what changed and the points that need to be checked
• Designed so that reviewing all chapters completes the PR review

The authors say they use Stage themselves, applying it not only to each other's code but also to their own code review. Logging in with a GitHub account lets commenting and approval sync naturally with the existing workflow.

Also, Stage is not trying to replace review bots like CodeRabbit or Greptile; it stands on the view that final responsibility should still rest with humans. In other words, the argument is that while bug detection can be left to automated tools, the process of understanding and judging "what actually ships" should be human-centric.
