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.
01
Own your agent
Prompts, flows and tools live in your repo.
02
Own your voice
Cloned or synthetic. Custom, and yours.
03
Invest in the harness
Guardrails and memory keep it safe. Models plug in and out.
04
Own the connection
No platform between you and your callers.
Multimodel
Change the model. Keep the agent.
