oto transcribes 100% offline on your Mac. Cloud services rent your voice back to you. We don't. All AI processing happens locally on your Mac's Neural Engine or GPU. No internet, no uploads.
Why own instead of rent?
Typical subscriptions cost $100+/year. oto is $8 once. You own it forever. No monthly bills to keep your own voice working.
How private is on-device processing?
Completely. Your voice never leaves your device. No telemetry. No "quality assurance" listening. Your thoughts stay yours.
Which languages are supported?
Support for 100 languages through AI models. Voice Activity Detection works across all languages. Automatic language detection with confidence scoring available.
