Decisions
Why was this architecture chosen?
Contorium
AI can read your code.
Contorium helps it understand why your project became what it is.
Preserve project decisions, reasoning, constraints, history, and evolving state — across AI tools, models, and sessions.

Scroll ↓A codebase is more than its current files. It also contains:
Why was this architecture chosen?
What trade-offs led here?
What must not be changed — and why?
How did the project become what it is today?
What is happening now, and what comes next?
AI coding tools can inspect the repository.
But the repository alone doesn't contain all of its intelligence.
Contorium preserves the knowledge that normally disappears between AI sessions — not just chat history, not just prompts, not just a snapshot of your codebase.
Contorium captures the project's:
So AI can continue from what the project already knows — instead of reconstructing everything from scratch.
One project. One intelligence layer. Every AI tool.
Instead of asking an AI to reconstruct your project from scratch:
Why was MCP added?
Contorium can trace the decision, alternatives, and reasoning behind it.
What changed this week?
See the project's evolution instead of reading through commits and chats.
What do we know about authentication?
Connect decisions, modules, constraints, and history around one topic.
What should I know before changing this?
Surface the project knowledge that matters before the next change.
Why was MCP added?
MCP was introduced because:
Contorium separates project intelligence from the AI tool using a local, structured architecture.
The interaction layer that lets humans and AI agents query, capture, and transfer project intelligence.
Decisions, reasoning, history, relationships, constraints, and evolution — structured and local.
The intelligence stays with the project — locally, inside the repository.
Understand how your project evolved over time.
Preserve decisions, alternatives, trade-offs, and reasoning.
Connect modules, decisions, people, constraints, and events.
Reconstruct what the project knew at a specific point in time.
Detect missing reasoning, stale decisions, and conflicting knowledge.
Turn project history into an understandable narrative for humans and agents.
Create a compact identity of the project for AI handoffs.
See how the project changed — and why.
Use the AI coding tool you prefer. Switch tools without losing the project's accumulated understanding.
One project.
One intelligence layer.
Every AI runtime.
Remembers conversations.
Retrieves relevant information.
Tracks code changes.
Preserves the intelligence behind the project.
What changed → Why it changed → What happened → What remains true → What comes next
Contorium gives AI coding tools a persistent intelligence layer — so every session can build on what came before.
