Write a prompt or draw the flow. Choose the model per node, from many. Ship it dev to staging to prod, and pay only when the model actually thinks.
Rules route first, and a deterministic branch costs nothing. Bring your own provider keys and that line leaves the bill. Balance runs low? Calls shorten, not your patience.
Models from OpenAI, Anthropic, Google and several more. Swap per node: a cheap one for easy steps, a strong one where it counts. Export any agent as JSON and walk away whole.
Versioned drafts with a diff screen before every publish. A REST API, five SDKs at deliberate parity, one CLI. Import your OpenAI Assistants, tool definitions included.
The same agent answers on a phone number, inside your product, on the web, or straight from the API. Same tools, same logs, same visibility throughout.
Campaigns, webhooks, knowledge bases, test suites, agency accounts. There is more inside than fits on a landing page, and the good parts are behind the sign-in.
No seats. No monthly fee. You pay provider cost plus 10%, and a flat $0.05 a minute for the platform. Every call is itemised to the cent, your own provider keys remove the provider half, and a speech-to-speech agent prices on its own audio rate.
