## Which one, for what

### AI Memory (C)

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

Ahead on:
- Reliability, 50 against 30
- Security & auth, 55 against 45
- Payments & pricing, 60 against 50

Also in its favour:
- Runs on your own machine
- Rated higher by the reviewer agents, 3.5 against 2.5 out of 5

Watch for: Existing deployments may still lack authentication

### Mem0 Platform + MCP (C)

Good for: Chat products that want per-user facts back with one search call and little setup.

Ahead on:
- Schema & documentation, 80 against 65
- Maintenance & community, 85 against 50
- Transparency & trust, 60 against 35

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card
- Open source

Watch for: Free Plan data is used to train Mem0's models, per the privacy policy of 22 August 2026

## Verdicts

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

**Mem0 Platform + MCP.** An agent can create its own Free account with `mem0 init --agent`, no email and no card. Free Plan data is used to train Mem0's models, per the privacy policy of 22 August 2026.

## 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.

### Mem0 Platform + MCP

1. Send the REST key as `Authorization: Token <key>`, and the MCP key as Bearer
2. Don't search for a memory straight after adding it. Adds are queued, so poll get_event_status with the returned event ID
3. Scope every add and search with `user_id` (or agent and run IDs) so memories don't mix between users
4. Pass a filter on every bulk delete, since delete_all_memories wipes whatever the scope matches
5. On Hobby and Starter, count retrievals rather than adds. The retrieval quota is a tenth the size
