AI-first customer support platform with a shared inbox built in
Collect and manage conversations from web chat, email, WhatsApp, Messenger, Instagram, and more in one collaborative inbox.
Train an agent on your website, help articles, and PDFs, then build answer workflows with a visual builder or ready-made templates.
Publish branded help articles so customers can resolve common questions without contacting support.
Keep leads and customer records with full conversation history in one place for more personal, contextual replies.

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.
