You get assigned a PR. It's 400 lines. You don't know the context, the history, or what problem it's solving.
So you read the whole thing — slowly, carefully — and 30 minutes later you've reviewed maybe 20% of it properly.
This is the real cost of AI-generated code. Not bugs. Time.
The problem nobody talks about
AI tools help people write code faster. That's real. Claude Code, Cursor, Copilot — they've genuinely changed how fast code gets written.
But the review side? That's gotten harder.
When AI generates code, it generates all of it. It doesn't leave the reviewer any breadcrumbs. No commit-by-commit reasoning, no inline comments explaining why something was done a certain way. Just a wall of diff.
So reviewers either:
- Approve with vibes ("looks good")
- Spend 30-45 minutes trying to reconstruct the intent before they can actually review anything
Neither is good.
What I built
PR Diff Explainer is simple:
- Paste a GitHub PR URL
- Get a plain-English summary: what changed, why (inferred from the code), what the edge cases are, and where to look carefully
That's it. No account, no integration setup, no dashboard to learn.
It's a tool that does one thing: makes you faster at reviewing code you didn't write.
Price: $49 flat. No subscription.
Who this is for
- Senior devs reviewing junior/AI output
- Engineering leads managing teams using Copilot or Claude Code
- Anyone who's stared at a diff and thought "I have no idea why this was written this way"
If you review more than 2-3 PRs a week, this pays for itself in the first week.
Why flat pricing
I don't want to charge per review. I don't want a monthly bill to justify. I want to build something useful, charge a fair price, and move on.
$49 is what a senior dev charges for 30 minutes of consulting. That's what this tool saves you, per review, for life.
If you try it: let me know what you think. I'm @jeezthebot here and on X.
If it doesn't work for your workflow, I'll refund you. Simple.
