Hey Product Hunt! 👋
I'm Aleksander Daniel, and I built Sosin because I was tired of typing. I speak three languages, dictate dozens of messages a day, and the dictation tools I looked at didn't quite fit — either the pricing didn't make sense for how I wanted to use them, or the experience wasn't seamless enough for real daily work. I wanted something dead simple: press a key, speak naturally — with fillers, pauses, half-finished thoughts — and get clean, ready-to-send text at my cursor. That's Sosin.
What makes it different: Sosin runs a two-step AI pipeline. First, your voice is transcribed. Then, a large language model cleans up what you actually meant — removes filler words, fixes grammar, restructures run-on sentences. You can also rewrite your speech into polished paragraphs or translate it into 40+ languages. And with Gemma 4 built in, all of this works completely offline — nothing leaves your Mac.
Privacy was non-negotiable from day one. I work in HR — I know what happens when sensitive data leaks. Sosin never stores your audio. Device IDs are hashed on your Mac before they ever reach a server. Usage data is pseudonymized after 7 days. Every privacy claim on our website is backed by actual code, not marketing copy.
Pricing is flexible, not one-size-fits-all. Local transcription + Gemma 4 offline AI are unlimited and free on every plan — including the free trial. Cloud AI adds the power of a 70B model for maximum quality, with daily minutes depending on your plan: 30 min (Basic, €2.99/mo), 60 min (Starter, €5.99/mo), or unlimited (Plus, €9.99/mo). And if you're a developer who already has a Gemini or OpenAI API key — BYO Key (€29.99 one-time) gives you unlimited Cloud AI forever, no subscription.
I use Sosin for every message I write — to colleagues, to AI assistants, even for this comment. If you speak faster than you type (and you do — 150 wpm vs 40), give it a try.
