Demo

Hear it handle a real call.

Five example agents at work. Listen to a recorded call, or talk to one yourself.

Support desk agent

For example, ask about ticket T2 and the agent will look up its status and assignee.

The agent reads and updates these while you talk.

Approach

Not built for enterprises. Built for the shop down the street.

  • Start small. One job at a time.
  • No IT team needed.
  • Delegate more when you're ready.

  • HVAC

    Books the job while the crew is on a roof.

  • Law office

    Takes intake calls. Never gives advice.

  • Vet clinic

    Schedules visits, flags the urgent ones.

  • Dance school

    Answers trial-class questions after hours.

Framework

Rent the models. Own everything else.

Sonido is an open-source harness. The models behind it can change any time; your agent, voice and customers stay yours.

  1. 01

    Own your agent

    Prompts, flows and tools live in your repo.

  2. 02

    Own your voice

    Cloned or synthetic. Custom, and yours.

  3. 03

    Invest in the harness

    Guardrails and memory keep it safe. Models plug in and out.

  4. 04

    Own the connection

    No platform between you and your callers.

Multimodel

Change the model. Keep the agent.
