Integration

One field. Persistent memory.

Add user_id or agent_id to the sansa.memory object and every model call starts remembering. Without having to set up a vector database, an embedding pipeline, or retrieval code.

How it works

Learns from conversations

Before each request, Sansa searches the memory store for that user_id or agent_id and injects relevant facts into context. After the model responds, new information is extracted and stored automatically.

Memory API

Your data, your rules

Use the Memory API to get more control over stored memories to build admin dashboards, handle deletion requests, or pre-populate context before a user's first conversation.
