## Which one, for what

### AI Memory (C)

Good for: AI Memory keeps shared project memory and task handoffs across coding agents.

Ahead on:
- Payments & pricing, 60 against 30

Also in its favour:
- Runs on your own machine

Watch for: Existing deployments may still lack authentication

### Supermemory API + MCP (B)

Good for: Apps that need user memory and document search over the same data, and for multi-tenant products that want a key per user.

Ahead on:
- Reliability, 65 against 50
- Schema & documentation, 85 against 65
- Agent ergonomics, 73 against 65
- Maintenance & community, 85 against 50
- Transparency & trust, 49 against 35

Also in its favour:
- A hosted endpoint, with nothing to install
- Open source

Watch for: No legal entity named in the terms or privacy policy

## Verdicts

**AI Memory.** Cross-agent task handoffs and shared search. Existing deployments may still lack authentication.

**Supermemory API + MCP.** 8-tool hosted MCP with OAuth and per-space read or write permission. No legal entity named in the terms or privacy policy.

## Before you call either

### AI Memory

1. Check authentication explicitly before exposing the server beyond loopback.
2. Exclude secrets and sensitive repositories from memory capture.
3. Back up memory and follow the version 3 migration guide.

### Supermemory API + MCP

1. Use one stable `containerTag` per user and a `customId` per session
2. Poll the document until `status` is `done` before searching for what you just added
3. Treat a 402 on search or profile as out of credit, not as a bug
4. Run the prompt-based mass forget with `dryRun` first
5. Call who_am_i on the MCP to see which spaces you can write to before adding
