Migrate auth to magic link
Dictate the run. Pick where your voice goes.
Push-to-talk that writes straight into the prompt — with a three-mode capability chain. Stream in-browser, transcribe fully on-device with wasm Whisper, or fall back to the cloud. You choose, and the choice sticks.

01
Three ways to listen, one button
Voice resolves the best path your browser can run: the native Web Speech API streams live interim text in Chrome, Edge, and Safari; true local Whisper transcribes on-device anywhere WebAssembly runs; and a cloud Whisper-1 fallback covers Firefox and in-app webviews. One mic button, the same push-to-talk gesture, whatever the engine underneath.

02
On-device by default — audio that never leaves
Local mode loads onnx-community/whisper-tiny.en into the browser via transformers.js and runs inference entirely on your machine. The model is a one-time ~145 MB download cached in browser storage; every transcription after that is instant and offline. No audio, no transcript, no round-trip — your voice stays on the device.

Your privacy preference, locked in
An inline chip cycles between auto, local, and cloud, persisted to localStorage. Auto picks the fastest available engine; local is a hard privacy lock that never silently falls through to the cloud; cloud is the explicit BYO-OpenAI path. Pick once and the setting follows you across sessions.

Speak, see it land in the prompt
Hold ⇧Space in the composer or tap the mic and start talking — final and interim text stream straight into the textarea you're already writing in, so the run picks it up on submit. Every transcription is recorded in the compliance audit log as a usage event, while the raw audio and text are deliberately never stored.
