Small teams move fast because they skip the paper trail but that means the only reliable source of truth left is the code itself. Docs go stale. Slack answers depend on who you ask. The code, right now, is just true.
The problem was never access to that truth. It was translation most people who need to know what actually shipped can't read a diff. pr-explainer removes that barrier.
Point it at any merged pull request, on any repo:
pr-explainer https://github.com/some-org/some...
You get back a plain-language explainer what changed, why the team did it that way, why it matters to you followed by a couple of quick recall questions so it's something you actually retain, not just skim.
Three ways people are using it:
Understanding any PR across their org, without pinging an engineer to translate it every time
Reviewing a teammate's PR outside their usual area
Running it on their own personal project's PRs including ones an AI coding assistant pushed just to stay on top of what shipped
How it's different: You describe yourself once your role, and what you're currently trying to understand better in a one-time profile file. Every explainer after that is calibrated to you: skips what you'd already know, slows down on what you're stretching into, never assumes unexplained jargon.
No API key required. If you already have Claude Code installed and logged in (subscription or key), pr-explainer rides on that nothing new to sign up for, no separate billing.
Free, open source, self-hosted. npm install -g @shilpi1958/pr-explainer.
Point it at any merged PR. Get a plain-English explanation of what changed and why — calibrated to whoever's reading — plus an interactive CLI quiz to check it stuck. No separate API key required.
