## 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 45
- Security & auth, 55 against 35
- Payments & pricing, 60 against 40
- Maintenance & community, 50 against 10

Watch for: Existing deployments may still lack authentication

### Context Mode Engine (E)

Good for: Context Mode Engine indexes tool output and session events locally for coding agents.

Ahead on:
- Transparency & trust, 42 against 35

Also in its favour:
- No key needed to call it

Watch for: Hosted-service restrictions under Elastic License 2.0

## Verdicts

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

**Context Mode Engine.** Local indexing and selective retrieval. Hosted-service restrictions under Elastic License 2.0.

## 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.

### Context Mode Engine

1. Choose the installation guide for the exact coding client.
2. Check host permissions before enabling code execution.
3. Review the Elastic licence before hosting Engine for others.
