Remembers you, not just the message
Sonic keeps a personal memory — your name, preferences, the people you mention and what you asked before. Every chat builds on the last, so you never have to repeat yourself and answers keep getting more personal.
AI assistant for WhatsApp
Delegate your day in a single chat.
Sonic is a personal AI assistant that lives inside WhatsApp. Ask it to remember things, chase people for answers, read your documents, run your group reminders and handle the busywork — while you get on with the work that matters.

Remind me to call the accountant every Monday at 9
Done — every Monday 09:00 I'll ping you. ✅
Ask Dana when the invoice is ready and let me know
On it. I messaged Dana and I'll report back the moment she replies.
Summarize this contract 📄
12-month term, auto-renews, 30-day notice to cancel. Want the risky clauses flagged?
One assistant. The whole back office.
Sonic replaces the scattered apps, reminders and follow-ups you juggle every day with one thing you already have open.
Everything you can hand off
Real, working features — all inside a normal WhatsApp chat.
Reminders that actually fire
One-time or recurring, in plain language. "Every Monday at 9", "in 20 minutes", "tomorrow at noon" — Sonic remembers and pings you on time, with timezone and daylight-saving handled.
Outreach that comes back with answers
Tell Sonic to message someone and ask a question. It sends the message, follows up if the reply is vague, and reports every answer back to you — so you stop chasing people.
Automatic group reminders
Schedule recurring messages for a whole WhatsApp group — standups, timesheets, rent, practice. Sonic posts them on time so you never have to nag the group again.
To-dos & notes that stick
Keep lists, notes and context in the conversation. Ask "what's on my list?" any time and Sonic remembers what you told it — across days, not just this message.
Document analysis
Send a PDF, contract, invoice or spreadsheet and ask. Sonic reads it and answers — summaries, totals, key clauses, the number you actually need.
Browse & search the web
Sonic opens real web pages and searches live — prices, availability, news, a detail on a site — and brings back the answer, with a screenshot when it helps.
Generate & edit images
Describe an image and Sonic creates it, or send a photo and ask for an edit — background removed, restyled, cleaned up. It quotes the cost before it spends.
Google Calendar, Sheets & Docs
Connect your Google account and Sonic can read your calendar, add events, update a sheet or draft a doc — always confirming before it changes anything.
Up and running in under a minute
No app to download, no dashboard to learn. If you can send a WhatsApp, you can run Sonic.

Let it work
Sonic handles it in the background — firing reminders, chasing replies, reading documents — and messages you the moment something's ready.
Built for people who'd rather delegate
Whether you run a business or just run a busy life, Sonic takes the admin off your plate.
A back office that never sleeps
Chase clients for documents and payments, keep your team's group on schedule, draft and update sheets, and never drop a follow-up — without hiring an assistant.
Your life, on autopilot
Recurring reminders for the things you forget, quick answers from the web, your documents summarized, and your to-dos in the one app you never close.
Keep the group moving
Automatic standup nudges, timesheet and deadline reminders, and shared prompts posted on time — so coordination stops living in someone's head.
Everything you might ask
Do I need to install anything?+
No. Sonic works entirely inside WhatsApp. You save a number and message it like any contact — there's no separate app, login or dashboard.
What powers Sonic?+
We've wired together a range of advanced AI models and tools — language understanding, web browsing, image generation and document analysis — into one super-capable assistant that picks the right tool for every task.
Is my data private?+
Sonic only sees the messages and files you send it, and it asks for confirmation before making any change to your calendar, sheets or documents. You stay in control of what it can touch.
What kinds of reminders can it set?+
One-time ("in 20 minutes", "tomorrow at 9") and recurring ("every Monday", "daily at 8am"), with timezone and daylight-saving handled. It can also post recurring reminders into a WhatsApp group.
How do outreach tasks work?+
You tell Sonic who to message and what to ask. It sends the message, follows up if the answer is incomplete, and reports each reply back to you — then stops when the task is done.
How do I get started?+
