Tools / Plivo / Plivo vs Twilio
Voice AI agents and communications APIs with per-minute pricing.
Plivo is a communications API platform whose homepage now leads with voice AI agents. You can build agents two ways: with code — SDKs for Python, Node, and Go, a REST API, and a CLI, with documented paths for bringing LiveKit or Pipecat agents onto Plivo — or with a no-code Agent Studio where you describe the agent in plain English and deploy from templates. Under both sits Plivo's telephony layer: self-serve SIP trunking, bidirectional audio streaming with noise cancellation, and phone numbers across 150+ countries. Alongside voice, the platform covers SMS, WhatsApp, and chat. The site lists example use cases such as sales lead qualification, order tracking, payment collection, feedback surveys, and identity verification, and includes a recorded demo call in which an agent reschedules a dental appointment and texts a confirmation. Stated figures: under 500 ms voice latency, 99.99% platform uptime, and 50+ languages supported. Customer logos displayed on the homepage include Meta, Uber, Discord, GoDaddy, and DocuSign.
Conversational AI and APIs for SMS, email, voice, and verification.
Twilio is a communications platform for developers. Its core APIs cover messaging (SMS, WhatsApp, and RCS), voice and SIP trunking, email (including an SMTP service), and phone number provisioning — local numbers, toll-free numbers, 10DLC, and short codes. There is also a Video API and Flex, a programmable contact center. For authentication, Twilio offers Verify (one-time passcodes) and Lookup (phone number intelligence). The customer data side, built on Segment, includes Connections, Warehouses, Unify, Engage, Audiences, and Journeys for collecting and activating customer profiles. Newer products sit under a Conversational AI umbrella: Conversation Relay for building voice AI agents, Conversation Intelligence for extracting context from real-time conversations, Conversation Memory for persistent customer context, and Conversation Orchestrator for keeping conversations connected across channels. Use cases listed on the site include user verification, fraud prevention, alerts and notifications, appointment reminders, mass texting, SMS marketing, IVR, and contact centers. Twilio targets industries from financial services and healthcare to retail, ecommerce, and the public sector, and positions itself for both startups and enterprises. The site is available in English, French, German, Japanese, Portuguese, and Spanish. Support options include a help center, paid support plans, and partner solutions.
