Why this matters

Every codebase eventually becomes a place only certain people fully understand.

It's not a skill problem. It's an information problem. The logic of how your system works lives inside engineers' heads, in Notion pages nobody updated, and in Slack messages nobody can find. As the team grows, this hidden knowledge becomes the biggest risk you're not measuring.

You onboard a new developer
They spend two weeks asking questions instead of shipping, because the architecture docs are either missing or wrong.
Someone leaves the team
They take six months of system knowledge with them. The codebase becomes a black box with no map.
You plan a big refactor
Nobody can tell you confidently what breaks if you touch the auth module. Everyone guesses.
A senior engineer reviews a PR
They have to trace function calls across 12 files just to understand if the change is safe.

The information exists — it's inside the code itself. The problem is that nobody has time to read all of it. Graphist reads it for you, automatically, every time you push.

How it works

Three steps. Then your codebase has a map.

01

Connect your repository

Link your GitHub account and choose a repository. Takes about 30 seconds. Graphist installs a webhook that watches for new pushes — no polling, no manual runs.

Works with any public or private GitHub repository.
02

Your architecture appears

Graphist reads your source code using AST parsing — not file trees, not import graphs, but the actual execution flow. Every route, function call, and database query gets mapped into a visual call graph.

Supports TypeScript, JavaScript, Python, and Go.
03

Ask it anything

The architecture copilot lets you query your codebase in plain English. Ask it which routes hit the payments database, what breaks if you change the user model, or where a particular function is called from.

Answers include highlighted paths on the live diagram.
