Press a hotkey, dictate, and clean text appears right where your cursor is. No switching apps, no copy-paste.
Available for macOS Sonoma or later
40 words per minute typing. 150 speaking. That gap is your untapped potential.
Record, transcribe, copy, paste, format. Five steps that should be zero.
Raw speech with no punctuation, no paragraphs. You edit more than you saved.
Press and hold Right ⌘. A small pill appears — Sosin is listening.
Talk as you normally would — with pauses, corrections, any language.
Clean, formatted text is pasted right where your cursor was. Done.
Raw speech in — polished text out
Born from a real need. Sosin exists because existing dictation tools were either too expensive, too bloated, or too careless with data. It was built to be the app that should have existed all along.
No 50-screen settings. No integrations with 200 services. One button, one job: turn your voice into text you're proud to send.
Sosin is built in Swift with AppKit — not a web wrapper, not a cross-platform port. It works the way a Mac app should: fast, clean, and deeply integrated with the system.
Audio is never stored. Device IDs are hashed. API keys live in the macOS Keychain. No analytics in the app, no ad network, no data trading. Sosin makes money from subscriptions — not from users.

macOS Dictation transcribes your voice — and stops there. Sosin's AI automatically removes filler words, fixes structure, and formats your text with paragraphs and lists. Rewrite mode transforms messy speech into polished emails or documents. Translation converts your dictation into 40+ languages on the fly. And while Apple's latest dictation model improves punctuation for English only, Sosin delivers accurate transcription across 90+ languages.
Sosin requires macOS 14.0 (Sonoma) or later and Apple Silicon. Local models need at least 8 GB RAM — 16 GB recommended for the Large model.
Yes. Local models transcribe your voice entirely on your Mac — no internet needed. With Gemma 4, you also get AI cleanup, rewrite, and translation offline. Cloud AI requires internet but uses a 15× larger model for the best quality.
Gemma 4 is an open-source AI model by Google that runs entirely on your Mac. When enabled, it cleans up fillers, rewrites text, and translates — all offline, with zero data leaving your device. It requires a one-time download of 5.3 GB. This feature is in beta. For the best quality, use Cloud AI — it uses a 15× larger model.
Cloud AI uses a 70-billion parameter model for maximum accuracy — it catches all fillers, handles complex rewrites, and translates precisely. Gemma 4 uses a 4.5-billion parameter model that runs on your Mac — it's private and works offline, but may occasionally miss fillers or produce less polished rewrites. Cloud AI when quality matters most, Gemma 4 when you want zero data leaving your device.
Transcription supports 90+ languages. AI translation supports 40+ languages.
With Local Models, nothing leaves your Mac. With Cloud AI, audio is sent encrypted for processing and is not stored after transcription. Your audio is never linked to your identity — there is no way to trace it back to you. Read our privacy commitment →

Privacy is not a feature we added — it is how Sosin was built from day one. We are a small, independent team. We have no investors to please, no ad revenue to chase, and no reason to collect more data than we need. Here is exactly what that means — and how we enforce it.
We never store your audio
Your voice is transcribed in real-time and immediately discarded. No audio file is saved on your Mac, on our servers, or anywhere in between. There is nothing to leak because nothing is kept.
We never see your transcriptions
Your dictation text is never stored on our servers. For managed plans, audio is processed through our secure server in memory only — it is never logged, saved, or accessible to anyone. For BYO Key, audio goes directly to your chosen AI provider. Your local dictation history stays on your Mac — we have no access to it.
We never link your data to your identity
Your device is identified by a SHA256 hash — a one-way mathematical function that cannot be reversed. We cannot determine which Mac sent an error report, even if we wanted to. Error reporting uses a separate hash from license activation, so the two cannot be connected.
We never train AI on your words
Your dictations are not used to train, fine-tune, or improve any AI model — not ours, not our AI providers'. All providers process your audio under data processing agreements that prohibit training on API inputs.
We never track your behavior
The app contains zero analytics. We do not track which apps you use, how often you dictate, what time you work, or what you talk about. The only numbers we store are minutes and requests per day — for subscription quota enforcement, nothing else.
We never sell or share your data
We make money from subscriptions. That is our only business model. Your data is not a product, not an asset, and not for sale. There is no ad network, no data broker, no third-party tracking.
Secrets in the Keychain
Your API keys and license key are stored in the macOS Keychain — the same encrypted system Apple uses for your passwords. They never appear in plain text files.
Local models, zero network
Local models — including Gemma 4 AI cleanup — run entirely on your Mac. No data leaves your computer. No internet connection is needed during use. The Gemma 4 model requires a one-time download; after that, everything is offline.
Error reporting is your choice
Error reporting is off by default. If you opt in, reports contain only technical metadata: app version, macOS version, error type. Never your text, never your email, never your license key. Reports are automatically deleted after 30 days.
Minimal data, maximum function
If you subscribe, we know your email, which plan you are on, how many minutes you used today, and your country code (e.g. 'EE' — no city or precise location). Your device ID is hashed — we cannot tell which Mac is yours. After 7 days, your email is replaced with an anonymous hash too. If you use BYO Key, your audio goes directly to the AI provider of your choice — it never touches our servers, and we store nothing. Trial users are identified by a device hash only. That is it — no names, no content, no behavior data.
