One memory layer.
Every AI platform.
Your agents recall everything — across Claude, GPT, Gemini, Cursor, and any framework. Persistent memory that works everywhere, instantly.
How It Works
12345678910from zerolatency import Memory mem = Memory("zl_live_...") # Store a memory mem.add("User prefers Python and hates meetings before 10am") # Recall — sub-100ms result = mem.recall("Schedule a code review") # → Python preference, no meetings before 10am. That's it.
Platform Statistics
Built for Agent Memory
Everything your agents need to remember, recall, and reason across sessions.
Temporal Intelligence
Memories decay, reinforce, and evolve over time. Half-life scoring ensures your agent prioritizes what's current, not just what's similar.
Knowledge Graph
Entity relationships with multi-hop traversal. Find connections between people, projects, and concepts — no Neo4j required.
Proactive Recall
Context injection without explicit search. Tiered loading (L0/L1/L2) fits your context window budget automatically.
Contradiction Detection
When facts change, old memories get superseded — not stacked. Correction cascading ensures your agent never serves stale context.
Negative Recall
Knows what it doesn't know. When context is missing, your agent says "I don't have that information" instead of hallucinating.
Custom Criteria
Define scoring attributes like urgency, joy, or confidence. Re-rank recalled memories by what matters to your application.
Version History
Full changelog per memory. Every update snapshots the previous state. Audit trail for compliance and debugging.
Webhooks
Real-time notifications on memory events. HMAC-signed payloads with retry logic and delivery audit logs.
Organization Memory
Shared memory across team agents. Promote individual memories to org level. Build institutional knowledge.
Automatic Secret Detection
Every inbound memory is scanned for API keys, tokens, and credentials. Secrets are blocked before storage — never accidentally persist sensitive data in agent memory.
Agent Orchestration
Multi-agent memory sharing with scoped access controls. Agents coordinate through shared memory without stepping on each other.
Self-Improving Memory
Confidence scoring that strengthens with reinforcement. Memories evolve based on usage patterns — frequently recalled facts gain weight, stale ones decay.

FAQ
What counts as a "memory"?
Each extracted fact, preference, or relationship from a conversation turn is one memory. A single conversation turn typically produces 1–5 memories.
Can I switch plans anytime?
Yes. Upgrade instantly, downgrade at end of billing period. No contracts, cancel anytime.
What happens if I hit my memory limit?
Extract calls will return a 429 error. Recall continues to work. Upgrade to a higher plan for more capacity.
What's the difference between Pro and Scale?
Pro gives you unlimited memories with 10 agents, plus webhooks, versioning, and batch operations. Scale adds Graph Memory, Negative Recall, Organization Memory, custom scoring criteria, and priority support — all at $89/mo (64% less than Mem0's comparable tier).
Do you offer annual billing?
Yes! Toggle the Annual switch on the pricing section above. You'll save 20% — Pro drops to $23.17/mo ($278/yr) and Scale to $71.17/mo ($854/yr).
