A proactive voice AI agent that runs on its own servers for instant, private conversations.
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.
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.
Rather than only chatting, the agent pursues defined objectives autonomously, making it suited to service, sales and lead-generation calls.
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.
