Four ways to keep speech useful.

Captions

Speech from your Mac's system audio becomes stable captions in a small, movable bubble. Recognition runs on the Mac.

Translation

Add a second line in another language with a local translation model while keeping the original speech available.

Dictation

Hold a configurable key, speak, and release. Silence-aware regions preserve language switches, while local cleanup removes clear fillers and repetitions. The result goes into the focused field when possible and always remains on the clipboard.

Transcripts

Save original and translated sessions in the app, then read them later or export SRT, WebVTT, Markdown, or plain text.

Local by default

Nothing leaves your Mac for daily use.

There is no account, tracking, telemetry, or audio upload. Models run on-device after download. The captions microphone is optional; dictation opens it only while the press-to-talk key is held.
