Claude and ChatGPT remember you. Team0 is shared by every agent.
Each assistant remembers you inside its own product. Team0 is one understanding that Claude, ChatGPT and every other agent you connect all read.
Where Team0 is different.
- Tell one agent, the others know
- Claude, ChatGPT, Claude Code, Codex, OpenClaw and other agents read the same understanding.
- Built from all your work
- Email, calendar, meetings, GitHub, Notion, HubSpot, Jira, Stripe and more, plus what your agents save.
- Every statement shows its source
- The exact line it came from, who said it, and when.
- Heard is not confirmed
- A remark floated once on a call is kept, labelled as heard. It never overwrites what is confirmed.
- Settled, or put to you
- A change is settled when the evidence settles it. When two people still disagree, both are kept and marked, and your agent asks you.
- Correct it once
- Fix a statement in one place, and every agent reads the fix.
Side by side.
Claude and ChatGPT memory’s column uses its own words.
| Claude and ChatGPT memory | Team0 | |
|---|---|---|
| Where it works | Claude: “the memory you use in chat is the same as in Claude Cowork.” ChatGPT: in ChatGPT | Every agent you connect, including Claude and ChatGPT |
| What it learns from | Your chats with that assistant. ChatGPT can also use your files and a connected Gmail | Agent conversations, email, calendar, meeting transcripts, documents, GitHub, Notion, HubSpot, Jira, Stripe and more |
| What it keeps | Claude: topics in a list of files. ChatGPT: saved memories, and insights from past chats | Statements with their source, status and history |
| When facts change | Updated as you chat | Heard never replaces confirmed. Disagreements are marked and put to you |
| Correcting it | Read, edit or delete memories in each assistant’s settings | Correct a statement once, for every agent |
Claude and ChatGPT memory details are from its own site and documentation, checked October 2026.
