Context42 keeps your AI sessions persistent. Decisions, architecture, and current state survive every session — so you never start from scratch.
Every decision, architecture choice, and current state is written to governed files that survive every session and redeploy.
Switch between Claude, GPT-4o, and more without losing your workspace. The context travels with you.
Explore to think, Build to execute, Review to critique, Production for full focus. Each mode scopes what the AI sees.
Every project scaffolds five governed files — decisions, architecture, open questions, current state, and what-we-are.
Give it a name and describe what you're building. Context42 scaffolds your workspace with five governed files automatically.
Choose Build, Explore, Review, or Production. Pick Claude, GPT-4o, or whatever model fits the task.
Your decisions, architecture, and current state are injected into every session. The AI knows where you are.
Capture what was decided, what changed, and where the next session starts. Everything writes back to your workspace files.
Free to start. No card required.
