An AI Assistant for Reminders, Files & Voice Notes — All in WhatsApp
Quick answer: Three jobs eat your day: remembering things, reading documents, and processing voice notes. An AI assistant in WhatsApp handles all three in one chat — it fires reminders on time, reads PDFs and invoices and answers questions about them, and transcribes voice notes to reply hands-free. Agent Sonic does all of it without a separate app.
Video transcript
Your assistant already lives where you do: WhatsApp. What if your assistant lived right inside WhatsApp — no new app, no new login, just a chat you already check a hundred times a day? Three things quietly eat your whole day: remembering stuff, reading documents, and dealing with voice notes. One chat handles all of them. Just say it: 'remind me to call the accountant tomorrow at ten.' It turns plain words into a real ping, right in the chat, one-off or every Monday. Send a PDF, invoice or contract and ask a normal question — 'what's the total?', 'when's the deadline?' You get the answer without reading every page. Typing slowing you down? Send a voice note — 'remind me to book the flights' — and Sonic transcribes it, acts on it, and answers you with a voice note back. All of it lives in WhatsApp, so it reaches you where you already are — not buried in some app you forgot to open. Reminders, files and voice notes — the everyday trio, handled in one place. Want it?

Reminders that actually fire
The best reminder is the one you set in two seconds and then forget about. In WhatsApp you just say it: "remind me to call the accountant tomorrow at 10" or "every Monday at 9 remind me to send the weekly update."
Agent Sonic turns plain phrasing into a real scheduled ping — one-off or recurring — and messages you in the same chat when it's time. You can ask "what reminders do I have?" or "cancel the dentist one" anytime.
Because it lives in WhatsApp, the reminder reaches you where you already look, not buried in an app you forgot to open.
Files read in seconds
Send a PDF, contract, invoice or spreadsheet and ask a normal question: "what's the total?", "when's the deadline?", "summarize the key terms." You get the answer without reading every page.
It works on text-based documents — the actual words, not scanned images or charts. For anything you'll need later, ask the assistant to remember the key figures so you can refer back.
| File | Ask |
|---|---|
| Invoice PDF | "What's the total and the due date?" |
| Contract | "What's the notice period and can I cancel early?" |
| Bank statement | "How much did I spend on subscriptions?" |
| Long report | "Give me the 5 main takeaways" |
Voice notes, answered hands-free
Sometimes typing is the slow part. Send a voice note with your question or task — "remind me to book the flights" or "summarize what we agreed" — and Agent Sonic transcribes it, acts on it, and replies with a voice note of its own.
That makes it genuinely usable while driving, walking or cooking: talk, get a spoken answer back, keep moving.
Reminders, files and voice notes are the everyday trio, and handling all three in one WhatsApp chat is exactly what Agent Sonic is built for. Request early access at tryagentsonic.com.
Frequently asked questions
How many reminders can I set?
Up to 100 active reminders at once, one-time or recurring. A one-time reminder can be from about 30 seconds up to roughly 12 months ahead.
What file types can it read?
Text-based PDFs plus .txt, .csv, .md and .html files. It reads the text content; it can't interpret scanned pages, photos of documents, or charts.

Both — when you send a voice note, Agent Sonic answers with a voice note too, and includes any links or lists as text alongside it.
