How do I change my chatbot's avatar?

Go to Settings > Appearance. Upload an avatar image in the Chat Header section that customers will see while interacting with your chatbot.

What appearance elements can I customize?

Chat header (name, tagline, avatar, colors), message colors and font size, suggested questions style, minimized display mode (icon or mini bar), position, auto-open, human-like messaging, welcome message bubbles, voice input, shadow, link behavior, footer text, and custom CSS.

How do I position the chat widget on my website?

In Appearance settings under Minimized-mode settings, choose left or right position, then adjust vertical and horizontal offsets in pixels to avoid overlapping with other elements.

Can I add a privacy policy link to the chat?

Yes, use Custom chat footer with markdown. Example: 'By chatting you accept our [Privacy Policy](https://www.example.com)'

What is the minified chat bar mode?

Instead of the standard chat icon, you can display a compact sender bar at the bottom of the page. Select 'Minified chat bar' in the Minimized display mode dropdown.

What is Human-Like Messaging?

When enabled, responses are split into multiple message bubbles shown gradually sentence by sentence, simulating human-like typing. You can configure the delay between bubbles.
