Orthan

Orthanc provides persistent memory for voice AI agents. With sub-200ms retrieval times and 99% accuracy, voice AI platforms like Vapi, Retell AI, and Bland AI can remember every caller interaction. Features include automatic fact extraction, contradiction detection, and per-caller memory isolation. HIPAA-ready design with simple two-API integration.

What to expect from an ideal product

  1. Orthanc Memory Engine connects to Vapi, Retell AI, and Bland AI through two API calls, so your voice agent starts remembering callers without rebuilding your stack.
  2. Every caller gets isolated memory storage, meaning one patient or customer never bleeds into another conversation, which matters for HIPAA-sensitive deployments.
  3. Automatic fact extraction pulls key details from each call and stores them instantly, so the next time that caller rings in, your agent picks up exactly where things left off.
  4. Sub-200ms retrieval keeps memory recall invisible to the caller, no awkward pauses, no robotic recaps, just a conversation that feels continuous.
  5. Built-in contradiction detection flags when a caller gives conflicting information across calls, so your agent works from accurate data instead of stacking up bad inputs over time.
