Capture Every To-Do the Moment It Hits You
Text it to WhatsApp the second it lands. Sonic files your to-dos, notes and 'remember this' bits, then hands them back when you ask.
Get it out of your head in one line
Dump it and move on
"Note: the supplier switched to net-30" - Sonic saves it word for word, no forms, no tags, no app to open.
Build your to-do list by chatting
"Add to my list: send the Q3 invoice, book the dentist, reply to Dana." Three tasks, one message, done.
Ask for it later in plain words
"What did I note about the supplier?" Sonic pulls it straight back, so nothing important slips through the cracks.
Voice notes count too
Send a quick voice memo while you drive. Sonic turns it into a clean, searchable note you can find later.
One memory that sticks
Sonic remembers your regulars, your suppliers and your quirks, so you never re-explain who "the accountant" is.
Clear it when it's done
"Mark the invoice as sent" and it's off the list. Your open items stay honest and short.
Why capture beats organizing
Good ideas rarely wait for a good moment. They show up mid-meeting, in the checkout line, or right as you're falling asleep. The problem was never a lack of tools. It's the three taps between the thought and a safe place to put it. By the time you've opened the app and found the right list, the thought is gone.
Sonic removes those three taps. You're already in WhatsApp, so you just type it. "Remember: renew the domain in March." "Note: Maya prefers morning calls." "Add to my list: chase the deposit." Each one lands the second it hits you, in the exact words you'd use out loud. No categories to pick, no project to file it under, no decision to make.
Recall works the same way. When you need something back, you ask like you'd ask a colleague who never forgets. "What's still on my list for today?" "What did I note about Maya?" Sonic reads back what you saved, cleanly, so you can act on it instead of hunting for it.
This is the quiet half of delegation: not the big scheduled reminders, but the hundred small things you'd otherwise carry in your head all day. Hand them to Sonic as they come, and your mind stays clear for the work that actually needs you.
Questions before you start
Do I need to install anything?
No. Sonic lives inside your normal WhatsApp chat. There's no separate app to download and no dashboard to log into. You save the number, send your first note, and that's the whole setup. If you can text a friend, you can capture a to-do.
How do I get a note back later?
Just ask in plain words. "What did I note about the office lease?" or "Show me everything I saved this week." Sonic keeps a persistent memory of what you tell it, so you can pull any note or task back without scrolling through old messages to find it.
Can I capture with a voice note?
Yes. Record a quick voice memo the way you already do on WhatsApp, and Sonic turns it into a clean, searchable note. It's handy when your hands are full, you're driving, or typing the whole thought would just slow you down.
What's the difference from a reminder?
Reminders nudge you at a set time. Capture is about getting a thought out of your head the instant it arrives, then finding it later. Sonic does both, but this page is about the quiet part: notes, to-dos and "remember this" bits you'd otherwise forget.
Is my stuff private?
Your notes and to-dos stay tied to your own chat and are there for you to recall when you ask. Sonic is built to keep your captured items to yourself, not to broadcast them. If privacy is a dealbreaker, ask us directly and we'll walk you through exactly how it works.
How much does it cost?
Sonic is in early access right now, so the best move is to request access rather than pick a plan. Head over, sign up, and we'll get you capturing to-dos in WhatsApp. You'll be among the first to try it as we open more spots.
Stop carrying it all in your head
Send your first note to Sonic in WhatsApp and let it hold the details while you get on with the work.
