GreatChat Memory vs Mem0, Letta, and Zep
9 min read
Long-term memory matters, but implementations differ. GreatChat stores facts and preferences for each user, then surfaces them when relevant — without exposing them as raw context bloat.
What’s in common
- Facts are extracted from conversations.
- Embeddings or semantic search find relevant memories.
- Users can inspect, update, and delete data.
Comparable systems worth reading
Mem0, Letta, and Zep all offer long-term memory products. Mem0 focuses on agent memory, Letta emphasizes memory OS concepts, and Zep highlights retrieval accuracy and observability.
In GreatChat, memory is treated as one layer of the assistant, not an external dashboard. You manage it directly from the memory page.
