No more explaining yourself.

Three steps to your shared memory.

  1. 1

    Create your vault

    With the WhyVault template or empty – set up in a few minutes.

  2. 2

    Connect your assistants

    Give Claude, ChatGPT or Cursor access to your vault. No installation.

  3. 3

    Get more done together

    Everyone works from the same context – you stay in the flow.

Your knowledge links itself.

Type [[ and WhyVault suggests matching notes. Every link becomes part of your network – and your agents follow the connections to find context.

Your life. In the right rooms.

Sort your knowledge into rooms by topic – so everything stays clear and relevant.

The WhyVault template starts you with this structure – or start completely empty. The vault answers why, your task tool answers what's next. How the structure works · View the template on GitHub

Open to every agent

Your knowledge is yours. Not your AI tool's.

Connect Claude, ChatGPT, Cursor or any other agent that speaks MCP. They all read and write the same vault.
