Read in 0.4 s, no model in the loop, by Claude, Codex, ChatGPT or Grok Bot. Same understanding, same evidence.

01 · Evidence arrives

A living understanding of you. Used by any agent.

Built from your real inbox, calendar, chats and meetings. Kept true as things change. Connect once, and every agent you use now, or switch to later, reads the same current picture.

Join the waiting listTest your agent first

Connect once and get

  1. Living understanding, no teaching period

    It arrives already knowing your people, meetings and promises, and every fact says who said it, since when, and what it replaced.

  2. Agent network

    Your agent talks to other people's agents on terms you set. Nothing private crosses a line you did not draw.

  3. Proactiveness

    Your agent knows what changed before it acts, and reaches out where its host can receive it.

    Push arrives for hosts that accept it. Others read the change feed before each turn.
  4. Meeting notes, included

    Mind0 sits in your meetings. Your agent gets the notes as part of the same understanding. Stop paying for a separate note taker.

Connects today to Claude, Claude Code, Codex, ChatGPT, Cursor and Grok Bot, any agent that speaks MCP. Instinct and Muse have no way in yet. We open one host at a time, in the order you tell us.

One email when your host opens. Nothing else.

How it is different

Memory APIs for developersmem0, Zep, Letta

The developer holds the memory and it starts empty. Mind0 is yours, and it starts full.

User-owned memory over MCPOpenMemory

A USB stick you fill by talking to agents. Mind0 fills itself from your inbox, calendar and chats, and keeps itself true.

Closed assistantsTown, Instinct

They learn you, then keep it. That understanding cannot leave their product, so changing agent means starting again. Mind0 is yours, and every agent you use reads the same one.

Memory you maintain yourselfA notes file, a rules file, your own index

It is only as current as the last time you updated it, and nothing tells you when it went stale. Mind0 writes itself from what already happened, and retires what stopped being true.

Hosted brainsGBrain

A brain kept as markdown pages you maintain. Mind0 keeps a living picture instead, where a newer fact retires the older one. And it can hold something it heard without believing it.

Note takersOtter, Fireflies

A transcript in another tab. Here the meeting becomes part of the understanding your agent already reads.

This brain already has a body.

Mind0 is the understanding behind Team0’s Chief of Staff. Same graph, same evidence, same rules. The Chief is what it looks like when the understanding also has hands: it drafts, schedules, joins your meetings and asks before it acts.

Connect Mind0 to the agent you already use, or let the Chief do the work. Both read the same current picture.
