Tried Vapi for a weekend build and ended up rebuilding my entire voice interface with it. Fast, clean, and crazy realistic voices. Game changer!
Our support lines were constantly overwhelmed, leading to long wait times and frustrated customers. Vapi's voice AI now handles the vast majority of our inbound calls instantly, eliminating wait times and significantly boosting customer satisfaction.
Vapi has been a tool I've had success building on for over a year now. They make creating, managing, and working with voice agents as easy as possible.
One of the best platforms for developing AI Voice Agents!
The voice of AI Phone Screener
Great place to start building AI Voice Assistants for developers like us!
Vapi was crucial for giving RingChef its natural voice. Their platform allowed us to seamlessly integrate and deploy our advanced voice AI agents, making our conversations incredibly human-like and effective for restaurant calls.
Our voice agent is powered by Vapi! We also considered other voice models but Vapi is great and the UI is very clear. We also had a great interaction with the vapi team during their demo day. Vapi is one of the best.
We found that Vapi was the highest-quality and most reliable voice model for Rizzard
It's been a great tool for voice interactions. I love their widget, which is a big part of the UX.
We started working with VAPI customers, originally resolving various connectivity challenges. As time progressed, we learned VAPI customers required more than just a connectivity tool - a tool to enhance VAPI's features was required. Through Cloudonix's APIs and Cloudonix scripting capabilities, VAPI customers started using VAPI and Cloudonix in ways that challenged and improved our backend systems.
Vapi serves as the critical backbone of our voice interaction system, handling all the complex voice AI management that makes PersonaCall's realistic customer simulations possible. Key capabilities Vapi provides:
Real-time voice processing that allows sales representatives to engage in natural conversations with AI personas Dynamic persona switching based on our Enneagram personality framework Contextual awareness that adapts responses based on industry, buying stage, and previous exchanges Conversation state management to maintain coherent, realistic interactions throughout training sessions Webhook integration with our Bubble.io application for seamless data flow Voice profile customization that gives each persona distinctive speech patterns and characteristics
Vapi's API-first architecture allows us to implement sophisticated voice recognition and response systems without building this complex infrastructure from scratch, significantly accelerating our development timeline.
We’ve tried a bunch of voice tools, but Vapi stood out for being dev-first and insanely responsive. Whether we’re testing AI phone flows or simulating sales calls, it just works — fast, flexible, and super clean to build with.
