Git Stores Code. What Stores Engineering Decisions?

Git is incredible.

It remembers every file.

Every commit.

Every branch.

Every merge.

But Git was never designed to remember why.

Months later, developers ask questions Git cannot answer.

Why was this microservice split?

Why didn’t we use Kafka?

Why does this API still exist?

Why was this refactor abandoned halfway?

The information existed once.

Usually inside someone’s brain.

Or an AI conversation.

Or a meeting.

Then it disappeared.

As AI becomes part of software development, this problem becomes even bigger.

We’re generating more code than ever.

But we’re preserving less engineering knowledge than ever.

The faster code is written,

the faster reasoning disappears.

Imagine pairing Git with a second layer.

Git tracks files.

Another layer tracks decisions.

Git records what changed.

A cognitive layer records why it changed.

Together they create something much closer to how humans actually understand software.

Not files.

Not folders.

Not commits.

But intent.

That feels like a much stronger foundation for AI-native development than simply giving models larger context windows.

Project Intelligence Runtime powered by CIL. Ask your project what happened, why it changed, and what comes next across any AI coding tool.

Project Intelligence Layer for AI Coding

Git remembers what changed.
Contorium remembers why.

Contorium is a local-first project intelligence layer that preserves the context, decisions, and reasoning behind software projects.

It helps AI coding tools understand not only your code, but also:

  • Why architectural decisions were made
  • What assumptions they depend on
  • How the project evolved
  • Which decisions are still valid

Supported environments:

  • Cursor
  • Claude Code
  • Codex
  • Gemini CLI
  • VS Code
  • Any MCP-compatible AI runtime

The Problem

AI coding tools are powerful, but they forget.

Every new session starts with the same problems:

Why was this architecture chosen?

Why don't we use another solution?

What is the current project direction?

What decisions are still valid?

Developers repeatedly provide the same context.

The code exists.

The reasoning disappears.


The Idea

Git stores code history.

Contorium stores project intelligence history.

Git tells you:

What changed.

Contorium tells you:

Why it changed.
