An AI chat widget for your website

One line of code adds a chat widget that answers visitors from your own content and captures leads, on every page.

Short answer: The Knowster widget is a chat box you add to any website with one line of code. It answers visitors from your own content and captures leads, and works on WordPress, Shopify, Webflow, or plain HTML.

Knowster's widget is a small script you drop into your site. It loads a chat bubble trained on your website and docs, so visitors get real answers instead of a contact form. It works anywhere you can paste HTML.

One script, every page

Copy one snippet into your site's HTML and the widget appears site-wide. No plugins, no framework lock-in. It runs on WordPress, Webflow, Shopify, plain HTML, or anything that accepts a script tag.

What the widget does

Answers from your content - powered by your knowledge base, not generic replies.
Captures leads - collects name and email in the chat. See lead capture.
Matches your brand - set the accent color, greeting, title, and starter questions.
Light and dark ready - looks right on any site.

Customize without code

Greeting, starter-question pills, accent color, and whether lead capture is on are all set from your dashboard or with data attributes. Change them any time without touching the snippet again.

Works on any platform

The widget is one script tag, so it runs anywhere that accepts HTML - WordPress, Shopify, Wix, Squarespace, or a custom site. There is no platform-specific plugin to maintain and no dependency on your theme; the chat bubble loads over your pages and works the same regardless of how the site is built.

Control where it shows

You decide where the widget appears and how it greets visitors - its position, its opening message, and which pages it shows on. A greeting tuned to the page ("Ask us about pricing or availability") does more than a generic hello, and showing the bot where questions actually arise matters more than putting it everywhere.
