ThunderPhone

What is ThunderPhone?

ThunderPhone is voice AI infrastructure for teams that need phone agents to handle real customer calls reliably. It combines speech recognition, language models, testing simulations, live monitoring, and issue detection into one self-serve platform. The product emphasizes accuracy on difficult phone audio, transparent pricing from low per-minute rates, and multilingual support. It is aimed at builders and operators who want production-ready phone agents for support, scheduling, sales, parts lookup, and similar call-heavy workflows.

How to use ThunderPhone?

1. Create a ThunderPhone account from the official website.
2. Build an AI phone agent by configuring its voice, knowledge, behavior, and task flow.
3. Test the agent with AI-caller simulations before sending real calls to it.
4. Deploy the agent on a real phone number for customer or operational calls.
5. Monitor live calls, review detected issues, and approve proposed fixes to improve reliability.
