Works at 35,000 feet
Draft the trip report on the flight home. Turn airplane mode on, press the hotkey, and start talking; transcription happens entirely on your Mac.

Offline dictation for Mac
Offline dictation for Mac that keeps working when the Wi-Fi doesn't. oto transcribes speech on your Mac's own hardware, so it types just as well on a plane, in a dead-zone café, or on a machine that never touches the internet.
$8 once
Offline by default
No account
No signal needed
Built for the places Wi-Fi isn't.
Cloud dictation dies the moment your connection does. oto was never depending on one.
Made for locked-down machines
If you work on an air-gapped or firewalled Mac, there's nothing to whitelist, because oto has nothing to send. Audio is processed on-device.
Local engines, real accuracy
Up to three local engines (Whisper, Parakeet v3, and Apple's on-device speech) run natively on your Mac. Offline doesn't mean second-rate.
How it works
Set up once, dictate anywhere.
1. Install and grab a model
Download oto and its speech models once, while you're connected. That's the last time it needs the internet.
2. Press your hotkey and speak
Tap to toggle or hold for push-to-talk, in any app on your Mac.
3. Text appears at your cursor
Your Mac does the transcription and auto-pastes the result, connection or not.
Only two things in oto ever touch the network, and both are optional: bring-your-own-key cloud engines, off by default, and the update check. Everything else runs on your hardware.
Common questions
Offline, without the asterisks.
Does offline mean lower quality?
No. The same Whisper models that power cloud services run locally in oto, with support for 100+ languages with Whisper, including automatic language detection.
Do I need to download anything first?
Just the app and a speech model, one time. After that, oto dictates and transcribes files with zero connectivity. Airplane mode is a fine way to prove it.
Dictation that doesn't need a signal.
Your voice, your hardware, your rules: $8 once, no subscription.
