AI Agent
A voice conversation that listens while it speaks
Full duplex: the Agent keeps listening while it speaks, so you can cut in and change course mid-sentence.
Try it in the ConsoleEvery step that creates, changes or ends something waits for your Allow, on the page you are using.
Try it in the ConsoleTalk in a browser with the JavaScript SDK today. Conversations on ESP32 devices are coming.

Task voice
Dictation and long recordings, every piece confirmed
Dictate a note or send a long meeting recording piece by piece as 16 kHz mono PCM. The text comes back as you go.
JavaScript QuickstartEvery piece is acknowledged. If the connection drops, it resumes from the last confirmed piece, and you can cancel at any time.
JavaScript QuickstartNext: ask a question about what was said, or change the text by voice.

AI Conference · Preview
Three or four people, one live voice room
Each person joins from their own browser, and everyone hears whoever is speaking.
Read the Conference guideWho joins, who speaks and who listens is decided on the server, not in the browser.
Read the Conference guideThree or four people with a fixed roster. Nobody can be added once the room starts; to talk as a different group, start a new room.

Manage projects, environments, applications and keys through the same public API your code uses.

SDKs
Two SDKs on the same server model
One client for Task voice in browsers and Node.js, and Realtime RTC in browsers.
Read the QuickstartAn ESP-IDF component for devices on the same server model, with a stable media-port contract; each SDK's capabilities are listed in the compatibility matrix.

Authority stays on the server
Security model
Clients are assumed to be public and untrusted. Every decision that matters is made and recorded by OneSay.
- Server-owned scope, Grants and deny-first authorization
- Short-lived tokens for browsers and devices; API keys shown once
- Explicit Consent before a sensitive action, recorded with its decision
- Task usage metered on the server from what actually ran; RTC and Agent usage settlement is still in progress
