Sona: Voice Notes, AI-Sorted

Ruilin

About this app

Your thoughts, spoken — your notes, organized. Sona is the AI voice notes app that turns a spoken sentence into a tidy, searchable second brain that also acts on what you say.

Hold the button. Say what's on your mind. Done — Sona's speech-to-text runs right on your phone, and AI files the note into the right notebook, writes a clean title, merges duplicates, and sets the reminder you asked for.

No typing. No folders to manage. No cleanup day.

SPEAK, DON'T TYPE
• Hold to talk — fast, accurate voice-to-text dictation, right on your device
• Release to file — every voice note lands in the right notebook automatically
• Prefer typing? Quick keyboard input is always one tap away

AI THAT ORGANIZES FOR YOU
• Auto-sorting into 30+ notebooks: work, ideas, shopping lists, expenses, health, pets and more
• Smart merge: say the same thing twice and it becomes one matter — not clutter
• Clean titles and one-line summaries, written by AI
• Fix anything in one tap: move a note to another notebook, or split a wrong merge

SMART CAPTURE THAT ACTS FOR YOU
• Mention a phone number, and one tap calls or texts it
• Mention a place, and one tap opens navigation
• Mention a link, and one tap opens it
• Log money and AI tells income from expense (+/−), with a running total
• Tap a captured time to drop it straight into your calendar

NEVER MISS A THING
• Say "tomorrow at 3pm" — a reminder is set, on time
• Today view: what's overdue and what's due today, one glance
• AI Review (weekly or monthly): a genuinely useful recap — your focus, what's overdue, your spending, and one concrete next step

MORE WAYS TO CAPTURE
• Attach photos to any note — receipts, whiteboards, parking spots
• Driving mode: a big, hands-free, glanceable screen for the car
• Voice search: hold and say "that reimbursement", "cat food", "call the client"

PRIVATE BY DESIGN
• Speech recognition is 100% on-device — your audio never leaves your phone
• Notes and photos are stored locally. No account. No sign-up.
• AI organizing uses text only, and you can switch it off anytime to go fully offline

WHENEVER SOMETHING COMES UP
• Driving home — "fill up the tank on the way" — hands-free, saved
• Mid-meeting — capture decisions and action items without breaking eye contact
• Out shopping or cooking — call out what you've run out of; it becomes a list
• Paying for things — "taxi, 45" — expenses and income tracked with a running total
• On a walk — catch that idea before it's gone
• After a call — "ring the plumber, 138 1234 5678" — one tap to dial later
• Planning a trip — "fly to Pudong on the 30th" — reminder set, one tap to navigate
• With kids or pets — "gave the cat its meds" — a log that builds itself
• End of the day — a quick voice journal of how it went

Great for busy professionals, students, parents, creators — anyone who thinks faster than they type.

Voice note taker, to-do list and AI organizer in one — a second brain you talk to.

Say it once. It's kept, sorted, and ready when you need it.
