Why no free trial?
I'd rather show you everything oto can do.
The Reality
Most transcription apps offer 'free trials' that are really just demos - limited accuracy, premium features blocked, cloud only. I could build that too, but why showcase limitations when I'd rather demonstrate capabilities?

Origin of oto.
Why am I paying monthly to use my own voice?
Every transcription app I tried had the same problems: bloated features I didn’t need, “free” tiers designed to frustrate me, and expensive monthly subscriptions — all for something that ran on my own hardware using open-source models.
I wanted to keep full control of my words, my work, and my tools. Something minimal. Hidden when I didn't need it. There when I did.
oto is built to work quietly, silently, and effortlessly. Speak your thoughts at the speed they come to you. Capture ideas before your fingers slow them down. Then refine them on your own terms.
oto is always lowercase because it isn't the headliner. You are. Your voice is what matters.
No cloud. No subscriptions. No bloat. Pay once, keep it forever. Just your voice, your Mac, and the words you choose.
