In Action
Memory that transforms conversations
The same caller. The same agent. Two entirely different experiences.
Without memory
Every call starts from zero
With Sysevo Memory
Caller known before first word
How It Works
Three phases. One seamless experience.
Memory runs silently in the background. Callers feel it, but never see it.
<100ms
before agent speaks
Pre-Call Recall
When the call arrives, the caller's phone number is matched against the memory database instantly. Their profile is injected into the agent's context before a single word is spoken.
- Name, preferences, and history loaded
- Last call summary available
- Agent greets by name from word one
During
the conversation
Real-Time Extraction
As the call unfolds, the memory system listens alongside the agent. Discrete facts (preferences stated, details volunteered, decisions made) are extracted and tagged with type, confidence, and source.
- Preferences, email, address, and more
- Confidence-scored per fact
- Sensitive data flagged and protected
After
every call ends
Post-Call Consolidation
When the call ends, the profile is updated. New facts are added, corrections applied, and a natural-language call summary stored. Every subsequent call begins richer than the last.
- Profile updated automatically
- Call summary and outcome recorded
- Corrections supersede old facts
Memory Profile
Everything that matters. Nothing that doesn't.
Caller Memory stores a structured profile for each returning caller, with two layers of knowledge that build naturally from every conversation.

people call.
