GitHub App

AI writes the code.
Can your team still review it?

Review tools miss half the bugs, and nobody has time to read every diff by hand. See what each pull request actually changes, as a live architecture map.

The problem

You do not understand the codebase anymore

AI is writing most of the changes now, faster than anyone can follow along.
Review tools catch roughly half the issues - the rest goes out unread.
When something breaks, you end up asking the AI to explain its own code.

The fix

Visualization keeps you in the loop

Every pull request becomes a live architecture map, automatically.
See exactly which dependencies and boundaries a change touches.
Understand the real impact in seconds instead of digging for hours.

From install to insight in three steps

Install the app

Add JigsawML to your org and pick the repositories you want mapped.

Open a pull request

Every PR triggers a fresh analysis of what the change actually touches.

See the impact

Get a live architecture map on the diff - dependencies, boundaries, and risk at a glance.

Built for AI-generated code

Ship AI-generated code with confidence. We'll watch the architecture.

The more of your code AI writes, the harder it gets to keep track of. This GitHub App is the governance layer that keeps up with it, reviewing every pull request automatically so you don't have to trade speed for control.

Drift detectionCatch architectural drift the moment AI-generated code introduces it - not months later.

Boundary guardrailsKnow instantly when a change crosses a service boundary or breaks a dependency contract it shouldn't.

Suggestions, not just alertsJigsawML doesn't just flag the risk - it suggests how to fix it, right on the pull request.

Governance on every PREvery pull request is reviewed automatically, so governance ships at the same speed as your code.

Built for reviewing code you didn't write

A picture is worth a thousand lines of diff

We turn a 2,000-line pull request into a visual diff, so you can see what actually changed at a glance instead of scrolling.

Catch what review tools miss

Most review tools only catch about half the risky changes. Full system context catches the other half.

Keep up with AI-speed code

Your map refreshes on every commit, so your understanding of the codebase doesn't lag behind the code itself.

Ask what a change affects

Type a question about your architecture in plain English and get an answer grounded in the actual code.

Color-coded change map

Added components show up green, removed ones red, updated ones amber. You can see the shape of a change before reading a line.

Diff summary at a glance

Files changed, lines added and removed, and anything that doesn't map to your architecture yet - all in one summary.

Know which PRs need a closer look

Nobody has time to review every pull request, even with a map. We classify each one from a local tweak up to an architectural change, so you know which ones actually deserve your attention.

See the risk before you merge

Every PR gets a merge verdict and a risk breakdown across security, reliability, and performance - a second opinion on the complex changes, not something you have to take on faith.

You can't review what you can't see.

AI isn't slowing down anytime soon, so give every reviewer the full picture on every pull request and stay in control.
