Supermemory remembers. Team0 understands.
Supermemory keeps your sources and what it learned from them. Team0 keeps what is still true, who said it, and which agent may see it.
Where Team0 is different.
- 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.
- 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.
Supermemory’s column uses its own words.
| Supermemory | Team0 | |
|---|---|---|
| What it is | “The default engine for memory and continual learning for agents” | One understanding of your work that every agent reads |
| What it learns from | Agent sessions and documents you send. Connectors: Google Drive, Gmail, Notion, OneDrive, GitHub, Granola, Web Crawler | Agent conversations, email, calendar, meeting transcripts, documents, GitHub, Notion, HubSpot, Jira, Stripe and more |
| What it keeps | It “derives memories (what it understood) and keeps chunks (the source)” | What it learned, with the line it came from. Agent conversations are deleted after 7 days |
| When facts change | For a contradiction, “updates win for ‘what’s true now’”, with history kept for audit | Heard never replaces confirmed. Disagreements are marked and put to you |
| Casual remarks | “Casual, non-meaningful chatter is less likely to become durable memory” | Kept, labelled as heard, and never treated as confirmed |
| What agents save | Captured into memory | Kept as that agent’s evidence, never trusted on its own |
| Per-agent access | Memory separated by namespaces you choose | A grant per agent, revocable alone, every read on the record |
| Hosting | Cloud, or self-hosted, including air-gapped | Hosted by Team0 |
