Intervo

About Intervo

Intervo is an open-source platform for building voice and chat AI agents, aimed at agencies and businesses automating tier-1 support, lead qualification, reception and product guidance. Agent creation is described as a four-step process: define the agent's purpose with a prompt, which generates a workflow tailored to the business; add knowledge by uploading company documents and files or pointing at training links; pick a voice from ElevenLabs or Azure; then publish and embed the agent on any channel with one click. Voice agents connect to phone numbers through a Twilio integration so calls are handled in real time, and the same agent logic can be deployed as a website chat widget, giving one configuration across both modalities. A lead CRM captures qualified contacts from conversations. The marketing page runs a live demo that calls the visitor's own phone number, which is a stronger demonstration than a recorded clip. Being open source is the positioning against closed voice-agent vendors, letting a team inspect or self-host the stack, with community documentation alongside hosted plans. The vendor cites 1,000+ agencies and teams. Pricing has an unusual shape: a free tier with the core widget, a pay-as-you-go entry point, and a subscription tier discounted very heavily from a much higher list price, so the published list figure should not be read as the transacting price.
