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. Type or send a voice note to remember things, read your documents, run your group reminders and handle the busywork — while you get on with the work that matters.

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.
Chat by text or voice — your call
On the Pro plan, send a voice note instead of typing and Sonic listens, understands and acts on it exactly like text — in any language you speak. Prefer to listen? Ask Sonic to reply with voice messages — in the tone and style you like — and it talks back, hands-free.
AI assistant on your smartwatch
Want AI on your smartwatch? Sonic runs inside WhatsApp, so it already works on any smartwatch — Apple Watch, Wear OS, Galaxy Watch and more — no watch app to install. Read answers on your wrist, dictate a question by voice, and get reminders as a tap.
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.
Your AI assistant, inside your groups
Sonic works in your favorite groups — just add it to any WhatsApp group you're already in. Anyone can @mention it to ask a question and get an instant answer, set reminders for the group, or use commands — all without leaving the group chat.
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.
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, reading documents, browsing the web — 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
Keep your team's group on schedule, summarize contracts and invoices, look things up on the web, and never miss a reminder — 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.
Hooks into your stack
Call your own HTTP APIs and pull answers straight from chat, browse and scrape the pages you need, and hand Sonic a URL instead of a dashboard — so it fits the tools you already use.
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 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 taking any action on your behalf. 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.
Can Sonic join my WhatsApp groups?+
Yes — Sonic works in your favorite groups: just add it to any group you're already in. Mention it to ask a question and it answers right in the group, it can post one-time or recurring group reminders, and group members can use its commands there too.
How do I get started?+
Request access below. We'll send you Sonic's number and a short guide, and you can start delegating straight away.
How do I subscribe — and how do I cancel?+
You can subscribe right here on the website: open the Manage subscription page, verify your WhatsApp number with a one-time code, and pick a plan — payment is handled securely by PayPal. Or, if you prefer, just send /subscribe to Sonic in WhatsApp. Cancelling works the same way: use the Manage subscription page or send /unsubscribe, anytime.
Can I send and receive voice messages?+
Yes — voice messages are part of the Pro plan. Send Sonic a voice note instead of typing and it understands and acts on it just like a text message — in any language you speak. You can also ask Sonic to reply with voice messages, in the tone and style you prefer, so you can listen instead of read, completely hands-free.
Can I use Sonic as an AI assistant on my smartwatch?+
Yes — Sonic works as an AI assistant on any smartwatch, including Apple Watch, Wear OS and Galaxy Watch. Because it runs inside WhatsApp, there is no watch app to install: Sonic's answers and reminders arrive as notifications on your wrist, and you can dictate a question by voice straight from the watch and read the reply there. Same AI assistant on your phone and on your smartwatch.
Hand the busywork to Sonic.
Get access and put your reminders, to-dos and admin on autopilot — right inside WhatsApp.
