Mem0 remembers. Team0 understands.
Mem0 adds memories for your agents and apps. Team0 keeps what is still true, who said it, and which agent may see it.
Where Team0 is different.
- 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.
- Heard is not confirmed
- A remark floated once on a call is kept, labelled as heard. It never overwrites what is confirmed.
- 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.
- Agents save evidence, not truth
- What an agent saves is labelled with its name. One agent cannot quietly rewrite what the others read.
- One understanding for every agent
- Each agent reads under its own access, and every read is on the record.
Side by side.
Mem0’s column uses its own words.
| Mem0 | Team0 | |
|---|---|---|
| What it is | “Drop-in memory infrastructure for AI agents and apps” | One understanding of your work that every agent reads |
| What it learns from | What your agents and apps send, through SDKs, an API and MCP | Agent conversations, email, calendar, meeting transcripts, documents, GitHub, Notion, HubSpot, Jira, Stripe and more |
| When facts change | “New memories are added without overwriting or deleting existing memories” | Heard never replaces confirmed. Disagreements are marked and put to you |
| Coding agents | The Claude Code plugin recalls before the first response of a session and sends activity in batches | Plugins read before every reply and save when a turn ends |
| What agents save | Messages, answers, changed files and test results, sent to memory | Kept as that agent’s evidence, never trusted on its own |
| Per-agent access | Memories organised by the identifiers you send | A grant per agent, revocable alone, every read on the record |
| Hosting | Cloud, or self-hosted, including air-gapped | Hosted by Team0 |
