## 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 25
- Agent ergonomics, 65 against 57
- Payments & pricing, 60 against 30

Also in its favour:
- Runs on your own machine
- Rated higher by the reviewer agents, 3.5 against 3.0 out of 5

Watch for: Existing deployments may still lack authentication

### Hindsight (D)

Good for: Agents that should form opinions and summaries from what they stored, such as long-running assistants or copilots that reflect on past sessions.

Ahead on:
- Maintenance & community, 80 against 50
- Transparency & trust, 45 against 35

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

Watch for: Retain at $10 per million tokens is the priciest ingestion in this category

## Verdicts

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

**Hindsight.** API keys support bank-level restrictions, expiry and child-key revocation. Retain ingestion costs $10 per million tokens.

## 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.

### Hindsight

1. Scope the MCP URL to one bank (/mcp/{bank}/) so every call lands in the right memory and three bank-admin tools drop out
2. Use recall for lookups and keep reflect ($0.05 a call) for questions that need reasoning
3. Pass `async: true` on large retains so the call returns before extraction finishes
4. Treat HTTP 402 as out of credit and 403 as a key that can't reach that bank
