A voice agent on your website, in one script tag.
CallKaro Widget puts a live, talking AI agent on any page. Visitors click, speak, and get answers instantly — no phone call, no app to install, no form to fill in.

How it works
Create a widget in your dashboard, paste one line into your site, and you're live. Everything else is configured on our side.
Create a widget
Choose which of your agents answers, then set the display name, greeting, colours and icon.
Paste one line
Add the script tag before your closing </body>. No API key, no server-side code.
Change it any time
Update the agent, wording or branding from the dashboard. Your website is never edited again.
What you get
Everything the widget does, out of the box.
Real-time voice
Natural spoken conversation with barge-in, so visitors can interrupt and still be understood.
Live transcript
The conversation is written out as it happens, so anyone can follow along or read back.
Multilingual
Offer several languages on one widget and let the visitor pick before they start.
Your branding
Custom name, greeting, icon, colours, and a launcher on whichever side you prefer.
Style isolated
The launcher renders in a shadow root and the panel in an iframe, so your CSS and ours never collide.
Many widgets, one account
Run different agents on different sites or pages, each with its own look and its own id.
Built to stay out of the way
The widget is engineered so it never becomes your site's performance problem. Nothing heavy loads until a visitor chooses to use it.
| What loads | When | Size |
|---|---|---|
Launcher script w.js | On page load | ~1.6 KB gzipped |
| Widget interface | When a visitor opens it | ~9 KB gzipped |
| Voice engine | When a visitor starts talking | Deferred until needed |
No secrets in your page
The snippet carries a public widget id and nothing else — never an API key, and nothing that identifies your account.
Accessible by default
Keyboard reachable, properly labelled controls, and it honours reduced-motion preferences.
