SOSIN

Speak. Text appears.

Press a hotkey, dictate, and clean text appears right where your cursor is. No switching apps, no copy-paste.

Available for macOS Tahoe or later

You speak 4× faster than you type

Slow typing

40 words per minute typing. 150 speaking. That gap is your untapped potential.

Copy-paste chaos

Record, transcribe, copy, paste, format. Five steps that should be zero.

Messy output

Raw speech with no punctuation, no paragraphs. You edit more than you saved.

Three steps. Zero friction.

1

Hold the hotkey

Press and hold Right ⌘. A small pill appears — Sosin is recording.

2

Speak naturally

Talk as you normally would — with pauses, corrections, any language.

3

Release — text appears

Clean, formatted text is pasted right where your cursor was. Done.

Built for people who write

Smart Cleanup

Automatic punctuation, capitalization, and paragraph breaks. Your speech becomes clean prose.

Auto-formatting

Bullet lists, numbered steps, and structured output when your speech calls for it.

A文

Translation

Speak in one language, get text in another. Powered by the same AI models that clean up your speech.

Privacy-first

Your data is yours. Local Models run entirely on your Mac. AI Models process audio in real-time and never store it — your voice is never linked to your identity.

Works everywhere

Sosin types into any app: email, Slack, Notion, Google Docs, your IDE. If you can type there, Sosin can too.

Good questions

What macOS version do I need?

Sosin requires macOS 26.0 (Tahoe) or later. Apple Silicon (M1/M2/M3/M4) is recommended for the best local transcription performance.

Does it work offline?

Yes. Local Models use WhisperKit running entirely on your Mac. No internet needed. AI Models require an internet connection but offer higher accuracy and smart features.

What languages are supported?

Local Models support 99 languages via WhisperKit. AI translation supports 40+ languages.

Is my voice data stored anywhere?

With Local Models, nothing leaves your Mac. With AI Models, audio is sent to Google or OpenAI for processing and is not stored after transcription. Your audio is never linked to your identity — there is no way to trace a recording back to you.

Can I use my own API key?

Yes. The Bring Your Own Key plan lets you use your own Gemini or OpenAI API key. You pay for API usage directly and skip the subscription.

How does the free trial work?
