Atlas is a production-grade memory backend for AI agents. Instead of losing context between conversations or cramming everything into a single prompt, Atlas gives your agents three distinct, interconnected memory stores that mirror how human memory actually works.
Stores raw conversation chunks as vector embeddings in a vector database. Enables fast similarity search.
Extracts entities and relationships into a knowledge graph. Supports reasoning.
A per-session sliding context cache in memory. Tracks rolling topic vectors and hot facts.
Atlas stores and retrieves your information using a multi-layer memory architecture designed for accuracy, speed, and context.
When you save information, Atlas automatically processes and organizes it.
When you ask a question, Atlas searches across all memory layers.
Atlas combines vector search, graph retrieval, and recency signals to deliver the most relevant context for your prompts.
Built to deliver accurate, secure, and long-term memory for your AI applications.
Atlas scores memories on four axes: Vector similarity, temporal Recency (Ebbinghaus decay), access Frequency, and graph Association strength. Recently-reinforced, highly-related facts always surface above stale noise.
Ask complex relational questions across up to 5 hops in the knowledge graph. Atlas traverses entity relationships and grounds LLM answers in retrieved facts — no hallucination.
Memories decay over time via the Ebbinghaus forgetting curve. Consolidation compresses related clusters into abstractions. Pruning removes low-confidence nodes below a configurable threshold.
Every memory write and read is scoped to a user_id derived server-side from your API key. No cross-tenant leakage is possible — even if a client sends the wrong user_id.
The atlas-mem package requires only requests. Async support via httpx is available as an optional extra.
