Intervo review
Build document-grounded voice and chat agents, with self-hosted and hosted options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Intervo provides voice and chat agents for businesses handling customer support, lead qualification, receptionist tasks, and communications. Teams can train agents on documents, websites, and knowledge bases, then deploy them through a website widget or connect them to phone calls through Twilio. It suits small teams looking to automate both voice and chat workflows, particularly those that value self-hosting or usage-based access. Organizations seeking a tightly scoped, ready-to-run phone service may prefer a simpler alternative.
Its plan structure offers distinct deployment choices. The Free plan is open-source and self-hosted, with full source code access, complete data control, unlimited customization, and community support. The Developer Plan costs $10 pay as you go and includes 2,000 AI credits, unlimited agents, unlimited training links, API access, and widget chat and voice. The Business Plan is $99 per month with annual billing and includes 50,000 AI credits, integrations, and the same widget and API capabilities. Enterprise adds commercial licensing, professional technical support, and advanced security and controls. The free trial lasts 7 days.
Intervo's workflow depth is a central strength: a visual builder can route conversations among specialized agents, while the system supports lead scoring, call routing and scheduling, live transcription, summaries, and interaction analytics. Telephony runs through Twilio, and listed connections include HubSpot, Salesforce, Zapier, OpenAI, Claude, Gemini, ElevenLabs, Microsoft Azure, and PlayHT. This breadth may appeal to teams combining call handling with CRM or LLM tools. However, prospective buyers should weigh the setup involved in connecting those pieces and the credit-based Developer Plan against their expected usage. Teams needing deeper enterprise controls can consider Enterprise; those wanting a simple standalone calling tool may find Intervo broader than necessary.
