Why Context42
01 · PERSIST
Sessions that remember

Every decision, architecture choice, and current state is written to governed files that survive every session and redeploy.

02 · MODEL
Any model, same context

Switch between Claude, GPT-4o, and more without losing your workspace. The context travels with you.

03 · MODE
Four modes of work

Explore to think, Build to execute, Review to critique, Production for full focus. Each mode scopes what the AI sees.

04 · GOVERN
Structured workspace

Every project scaffolds five governed files — decisions, architecture, open questions, current state, and what-we-are.

How it works
01

Create a project

Give it a name and describe what you're building. Context42 scaffolds your workspace with five governed files automatically.

02

Pick a mode and model

Choose Build, Explore, Review, or Production. Pick Claude, GPT-4o, or whatever model fits the task.

03

Work — context is loaded automatically

Your decisions, architecture, and current state are injected into every session. The AI knows where you are.

04

End the session — nothing is lost

Capture what was decided, what changed, and where the next session starts. Everything writes back to your workspace files.
