The right context, on every call.
Mem0 turns conversations and agent activity into durable memory, scopes it to the right identity and retrieves only what matters for the current request.

THE PROBLEM
]
Context stuffing gets expensive before it gets intelligent.
Every call pays for old history
Token cost grows with everything remembered rather than what the current request needs.
Memory gets mixed or trapped
Without identity scopes, context either leaks across workloads or stays locked inside one tool.
Old facts keep looking current
A memory system has to maintain what is correct—not merely retrieve similar chunks.
[
PRODUCTION MEMORY SYSTEM
]
Memory that stays controlled, isolated and correct.
Extraction and retrieval are only the mechanism. Production memory also needs rules for what is stored, explicit identity boundaries and a way to preserve change over time.
[
CONTROL
]
You decide what becomes memory.
Custom instructions and categories define what Mem0 should include, exclude and label before storage.
[
IDENTITY & SCOPE
]
Keep every memory inside the right boundary.
Mem0 applies explicit app, user, agent and session filters before retrieval, so each request searches only inside the identities it belongs to.
[
TRUTH MAINTENANCE
]
Context that stays correct over time.
Inferred writes check for contradictions, preserve chronological states and let retrieval use the fact that is relevant now.
[
HOW IT WORKS
]
Extract. Scope. Retrieve.
Raw history becomes durable memory. Identity keeps it inside the correct boundary. Retrieval assembles the smallest useful context for the current request.
[
01 EXTRACT
]
Turn interactions into memory
A single pass creates compact memories from conversations, actions and confirmed outcomes.
[
02 SCOPE
]
Keep memory with right identity
Attach each memory to a user, agent, app or session before retrieval begins.
[
03 RETRIEVE
]
Assemble context for this request
Semantic, keyword and entity signals find what matters now—not the entire history.
