Kenning's take

What it does

Vapi gives developers the infrastructure to build voice agents that answer support calls, qualify leads or book appointments. It connects speech recognition, a language model and a voice provider of the developer's choice, and handles telephony, monitoring and call testing. Billing is per minute, with model costs passed through at cost.

• Choice of transcriber, LLM and voice providers

• Call testing and simulation
• Real-time monitoring of calls
• SOC 2, HIPAA and PCI compliance

Who it suits. Developers and companies putting AI agents on phone lines for support, sales or scheduling.
