Who should pick which

  • QSR chain operator
    Pick: Presto Voice

    Presto is purpose-built for drive-thru with proven upselling and integrations, recently adopted by Dairy Queen. Intervo lacks drive-thru specialization.

  • Agency building voice AI solutions
    Pick: Intervo.ai

    Intervo's open-source, customizable platform with multi-LLM and self-hosting is ideal for client projects requiring data control and flexibility.

  • SaaS company needing customer support automation
    Pick: Intervo.ai

    Intervo's chat/voice widget, workflow automation, and Tier-1 support can be embedded or integrated via API at freemium entry.

  • Independent restaurant with no drive-thru
    Pick: Intervo.ai

    Presto only serves drive-thrus. Intervo can handle phone ordering and website chat at low cost with flexible deployment.

  • Enterprise needing on-premise compliance
    Pick: Intervo.ai

    Intervo's self-hosted open-source model provides full data control, unlike Presto's cloud-only approach.
