Supermemory is a memory option for building AI agents. Memory graph plus automatic user profiles, with connectors that sync from Drive, Gmail, Notion and GitHub.
Worth knowing. Closest thing here to memory and RAG in one product: the graph tracks contradictions and recency, and the connectors mean you are not writing an ingestion pipeline first.
