mem0

Often requires a separate vector DB.

memorg

CLI + library; no required cloud account.

mem0

Cloud-first; CLI exists but is a wrapper around the API.

Keyed memory: `(user_id, agent_id, session_id)`.

mem0

Similar keying model.

Frequently asked questions

Does memorg work with any LLM?

Yes — memorg is storage and recall; the LLM is your choice. The example uses an OpenAI-compatible client but you can plug in any embedding model.

How does memorg handle memory provenance?

Each memory entry is stored with the source (turn id, user, agent). Provenance tracking is on the roadmap.
