Sotto vs Aqua Voice: Local One-Time vs Cloud Subscription
Aqua Voice and Sotto take opposite approaches to the same job. Aqua runs its Avalon model in the cloud and bills $10 a month for Pro (unlimited words); Sotto runs Whisper and Parakeet on your Mac, works offline, and costs $49 once for up to 3 Macs. Aqua's pitch is a model tuned to technical terms and screen context; Sotto's is privacy and a one-time price.
TL;DR
If you dictate on a Mac, want offline use, and prefer paying $49 once instead of every month.
$49 one-time, 3 Macs
If you want a screen-aware cloud model and mostly dictate with an internet connection.

Why People Compare Sotto and Aqua Voice
The subscription adds up
Aqua Voice Pro billed annually is $288 over three years, and Max — the tier with realtime mode — is $864. Sotto stays at $49 total. If you keep dictating for years, the one-time license wins by a wide margin.
Offline and privacy
Aqua processes speech on its servers, so dictation dies without a connection. Sotto's local models keep working on planes and behind firewalls, and audio never leaves the Mac unless you opt into a cloud provider.
The free tier is a taste, not a plan
Aqua's free plan stops at 1,000 words, full stop — that is a demo, not a daily driver. Sotto has no free tier either, but its one-time $49 covers everything from day one.

Frequently Asked Questions
Is Aqua Voice cheaper than Sotto?
Only in the short run: Aqua's free tier gives 1,000 words at $0, but its Pro plan costs $288 over three years billed annually, versus $49 once for Sotto. For daily dictation Sotto is cheaper from the first year.
Does Aqua Voice work offline?
No. The Avalon transcription model runs on Aqua's servers, so dictation requires an internet connection. Sotto's local models work offline.
Which is more accurate, Aqua Voice or Sotto?
Aqua publishes a 97.4% key-term accuracy score for Avalon on its AISpeak-10 benchmark, strong for technical speech. Sotto uses Whisper and Parakeet v3 locally with 90+ languages. The practical difference is context: Aqua reads your screen, Sotto does not.
