Your context is everywhere.

It doesn’t have to be.

Four conversations. Two coding sessions. A doc. Some notes somewhere. Cotext is one place where you and your tools build context together — and nothing gets lost.

No account needed.

Every time you start a new session, the context resets. The decisions, the research, the reasoning — gone. You re-explain. Your tools re-discover. The work doesn’t build on itself.

A context tree

for you and your tools.

Every conversation, decision, and draft accumulates into a persistent tree. Your tools can reference it. You can see who contributed what. The context compounds — it never resets.

Build

Create documents, briefs, and research nodes. Organize them into a tree that mirrors how you think. Each node is a unit of context your tools can read and build on.

Collaborate

Bring your tools — Claude, ChatGPT, Cursor, or anything that speaks MCP. They draft, suggest, and refine inside your tree. You review every contribution before it sticks.

Compound

The tree grows. Each session builds on the last. Your tools start new conversations with full context of what came before. Nothing is lost.

See who contributed what.

Every paragraph has an author. The colored bar tells you at a glance — green means you approved it. Red means it’s waiting for your review. Nothing changes without you.

Any tool. One tree.

Today it works with Claude, ChatGPT, Cursor, and any tool that can reach an API. Tomorrow, tools connect natively — discovering your context tree, reading what came before, and contributing where they can help.
