Zero memory latency.
Your agent recalls everything.
Instantly.
Sub-100ms memory recall for AI agents. Add memories, get them back — no configuration, no tuning, no waiting. It just works.
from zerolatency import Memory
mem = Memory("zl_live_...")
# Store a memory
mem.add("User prefers Python and hates meetings before 10am")
# Recall — sub-100ms, always
result = mem.recall("Schedule a code review")
# → Python preference, no meetings before 10am
# → That's it. No config. It just works.Platform Statistics
Chrome Extension
Capture memories from ChatGPT, Claude, Gemini & Perplexity automatically.
Every conversation you have with any AI assistant is automatically extracted into your memory layer. No copy-paste. No manual logging. Just talk — your agent remembers.
Built Different
Not another RAG wrapper. An actual memory system.
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When facts change, old memories get superseded — not stacked.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.
