One-click WhatsApp messaging, on any webpage
- Watobot's browser extension finds phone numbers on any page you're viewing and adds a WhatsApp icon next to each one — click it to start chatting instantly.
- Built for reaching out to leads, contacts, and lists fast, one click at a time.
- Great for bulk WhatsApp messaging.
Features
No more copy-pasting phone numbers
No more copying phone numbers into WhatsApp Web to message someone — click the WhatsApp icon right next to the number, wherever you found it.
Template support
Create message templates once, then send pre-defined messages quickly instead of typing the same thing out every time.
Delivery history, with one-click retry
See the status of every message you've sent, and retry any failed one in a single click.
Share one WhatsApp account with your whole team
WhatsApp itself caps a single account at 4 linked devices. Since the extension sends through your Watobot API key rather than linking as its own device, any number of teammates can use the same connected WhatsApp account.
How it works

chrome://extensions. - Turn on Developer mode (top-right toggle).
