Introduction

Stage starts from the observation that AI writes code faster than teams can review it. It turns every pull request into a story you can follow: a prologue explains why the PR exists, the root cause and what it does, followed by key changes and chapters that walk through the diff.

Rather than replacing human review, Stage reorganises it, so reviewers understand intent before reading code. There is also a CLI.

It pairs well with an AI reviewer that leaves comments: one tool finds issues, Stage helps people understand the change.

Stage is most useful on the pull requests people dread: large refactors, migrations and agent-written features that touch many files. Reading the chapters first gives reviewers a map, so their attention goes to the risky parts instead of the boilerplate.

Launch and background: Stage was posted to Hacker News as a Show HN on 16 April 2026.
