Sotto: Offline Speech to Text

Sotto is an offline speech to text app that turns your voice into clean, searchable voice notes on your phone. No account, no cloud and no internet needed after the first setup.

Tap the mic, speak naturally and watch your words appear sentence by sentence. When you stop, Sotto tidies punctuation and capital letters so your note is ready to save, edit, listen to or share.

SPEAK. SEE IT. SAVE IT.
• Live voice to text: each sentence appears moments after you pause
• Punctuation, capital letters and filler words are cleaned up automatically
• Switch between Raw and Cleaned versions of every voice note
• One tap to record, one tap to stop

PRIVATE BY DESIGN
• Offline speech recognition runs on your phone using OpenAI's Whisper model
• Your voice and notes never leave the device
• No sign-up, no login, no subscription
• Works in airplane mode after a one-time speech model download (about 60 MB)

KEEP VOICE NOTES ORGANISED
• Smart titles, rename any note
• Search across every note and pin the important ones
• Key points for longer notes, picked from your own words (not written by AI)

USE YOUR NOTES ANYWHERE
• Copy in one tap or share to any app
• Export as PDF, Word (.docx) or plain text
• Listen back with text-to-speech, sentence highlighting and 0.5x to 2x speed

Choose the speech model that suits your phone: fast, balanced or more accurate. Light and dark themes included.

GOOD TO KNOW
• Sotto currently transcribes English
• Accuracy depends on your voice, accent, microphone and surroundings
• First launch needs an internet connection once to download the speech model

Great for quick ideas, reminders, shopping lists, journaling, study notes and meeting follow-ups.

Sotto: say it once, keep it private.
