About Plivo
What is Plivo?
Plivo is a cloud communications platform that lets you build and deploy human-like voice AI agents. It combines a no-code agent studio, programmable APIs (for LiveKit, Pipecat, or custom code), and carrier-grade telephony in one place. The platform handles the heavy lifting—real phone numbers, SIP trunking, audio streaming—so you can focus on crafting great customer conversations.
What problem does it solve?
Traditional voice bots sound robotic and are hard to integrate with existing phone infrastructure. Plivo solves this by offering ultra-low-latency voice AI (under 500ms) with 99.99% uptime, ensuring natural, real-time conversations. It also eliminates the complexity of juggling multiple vendors: you get telephony, AI models, and transcription in one transparent per-minute price.
Who is it for?
Plivo is ideal for businesses that need to scale voice operations—think call centers, healthcare clinics, delivery services, or any company handling high volumes of inbound/outbound calls. It’s particularly strong for developers wanting to embed voice AI into existing apps, and for non-technical teams who can build agents using the no-code studio. It’s not for those needing SMS or WhatsApp out-of-the-box on the free tier—those are Enterprise-only.
Real use cases
Example: a dental clinic uses Plivo to answer calls, reschedule appointments, and send confirmation texts (as shown in the recorded demo). Other use cases include post-delivery feedback calls, order status lookups, and outbound sales or support agents. Plivo’s AI agents can call external tools (like CRMs) to complete tasks in real time.
