In their own words
Intervo
Intervo is a platform for creating AI voice and chat agents for business communication, including customer support, lead qualification, reception, onboarding, automation, and internal help. Businesses can give agents context from documents, websites, or knowledge bases. A website widget lets visitors type or speak with an agent, and the documentation describes connecting agents to phone numbers through Twilio for inbound and outbound calls. Intervo says agents can use OpenAI, Claude, or Gemini models and ElevenLabs or Microsoft Azure voice engines. Listed integrations include Calendly, webhooks, Intercom, Google Sheets, Cal, Slack, and Zapier; a custom API is marked as coming soon. It runs on the web, through an API, or as a self-hosted deployment. The free self-hosted plan includes source code under the MIT License and community support. Developer costs $10, paid once, while Business costs $129 a month; the pricing page also shows yearly billing at $99 USD/month and $129 USD/month.
