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.

AI-powered customer conversation platform for B2C messaging at scale
Bring WhatsApp, TikTok, Instagram, Facebook, Telegram, email and web chat into one shared inbox so no customer thread gets lost between apps.
AI agents qualify leads, answer routine questions, route to the right teammate and follow up automatically when conversations go quiet.
Track tags, custom fields, lead status and lifecycle stage per contact, and move deals through a pipeline without a separate CRM.
Reach thousands of customers with one message, and capture new leads directly from social ads and website links.
