Quantz®

Quantz is a proactive voice AI agent from Tokyo-based ThinkX that answers and places calls in real time, autonomously pursuing business goals instead of merely chatting.

Private, programmable voice engine

ThinkX describes Quantz as a completely private, flexibly programmable and ultra-fast conversational agent foundation system built on a proprietary codebase of about 670,000 lines.

Fast real responses

The realtime engine is designed to deliver the substantial content of an answer immediately, rather than stalling the caller with filler acknowledgements while it prepares the reply.

Goal-driven conversations

Rather than only chatting, the agent pursues defined objectives autonomously, making it suited to service, sales and lead-generation calls.

Self-hosted economics

Because it runs fully on ThinkX's own servers, the company claims a large cost advantage over systems that combine third-party APIs with cloud infrastructure.
