WHAT IT DOES · WRITTEN BY ATLAS, UNREVIEWED BY AN OWNER

ThunderPhone provides AI-powered voice agents that place and receive real phone calls, or run embedded in websites and apps, for use cases like customer support, scheduling, pre-sales, and outbound campaigns. It offers tiered voice models (Spark, Bolt, Storm) with per-minute pricing, and supports inbound calls, outbound campaigns, SIP trunking, and integrations with CRMs and calendars. It is aimed at businesses that want to automate phone-based customer interactions at lower cost than human call centers or other voice AI platforms.
