WebBrain for websites
Add an AI guide to your website.
Paste one line of code and every visitor can ask about the page they're on. WebBrain reads the page, answers from it, and, if you allow it, fills in forms and clicks through for them.
Free No credit card. Nothing for visitors to install. Try the live demo
Embed code
Paste it before </body>.
<!-- WebBrain for websites --> <script src="https://sites.webbrain.one/embed.js" data-site-id="site_your_id" defer></script> <!-- That's it. The launcher appears in the corner, styled the way you set it up. -->
<!-- Any element can ask a question --> <button data-webbrain-ask="Compare these plans for a team of 5"> Which plan fits me? </button> <!-- Or let WebBrain act, when Ask + Act is on --> <button data-webbrain-act="Fill in the demo request form"> Fill it in for me </button>
// Open the assistant from your own UI WebBrain.open(); // Ask about the current page WebBrain.ask('Summarize this page in 3 points'); // Let it act (sites with Ask + Act enabled) WebBrain.act('Add the annual plan to my cart'); // Pick up dashboard changes without a reload WebBrain.reloadConfig();
Live on your site in three steps.
No SDK to install and no build step. WebBrain loads after your page does and stays out of your styles.
-
Add your site
Enter your site's address in the dashboard. You get a site ID and your script tag right away.
-
Paste one line
Put the script before
</body>. Anything that lets you add a script tag works: static sites, CMS themes, and single-page apps. -
Visitors ask
A launcher appears in the corner. Visitors ask about the page they're on, and WebBrain answers from what's actually there.
You decide what it can do.
Every setting lives in the dashboard and reaches your site the moment you save. Visitors never see a key, a model picker, or a setup screen.
Ask, or Ask and Act
Keep WebBrain read-only, or let it type, tick boxes, and click buttons for the visitor, with a visible glow and a Stop button while it works. The server enforces your choice.
Your model, your key
Use any OpenAI-compatible endpoint: OpenAI, OpenRouter, Groq, DeepSeek, Gemini, Together AI, xAI, or your own server. Keys stay on the server.
Starter questions
Put one-click questions in the drawer, like “Summarize this page” or “Compare the plans,” so visitors know what to ask.
Buttons in your page
Turn any element into a question with data-webbrain-ask, or add “Explain this” buttons to every matching section with a CSS selector.
Highlight to ask
When a visitor selects text, a small pill offers to explain exactly that passage.
Your look
Light, dark, or matching the visitor's system. Choose the launcher style, icon, label, accent color, and corner.
It's free.

Will it work on my site?
</body>, yes: static sites, CMS themes, and single-page apps alike. The assistant draws itself in its own shadow DOM, so your styles and its styles don't collide.
