Decide what must survive a session: explicit facts, readable notes, or a self-hosted memory service. Storage ownership and retrieval behavior matter more than the number of tools.
Entities, observations and relationships in a persistent graph. Best suited to structured facts; set a deliberate MEMORY_FILE_PATH rather than relying on a working-directory default.
Read upstream documentationKnowledge stored as Markdown notes. Prefer it when you want to read and edit the underlying notes yourself; choose between local storage and the separate cloud offering.
Read upstream documentationThe STRATA maintainer directs new users to SOLUM. Review the successor and migration notes before adopting this self-hosted family; do not treat the older STRATA repository as the current recommended release.
Read upstream documentationFirst check: save a disposable fact, restart the client, retrieve it and delete it. Confirm which file, project or service holds the data, and whether another client is intentionally sharing that storage.
