One script tag. Any website. Done.
WordPress, Shopify, Squarespace, Wix, or custom HTML. One line of code and Brian is live. Shadow DOM keeps everything isolated.
Brain Buddy deploys with a single script tag. Copy it from your dashboard, paste it into your website's HTML (before the closing </body> tag), and Brian is live. It works on WordPress, Shopify, Squarespace, Wix, Webflow, and any custom HTML website. The widget loads inside Shadow DOM, which means your website's CSS cannot affect the chat widget and the widget's CSS cannot affect your website. Complete isolation. Zero conflicts. No plugin needed.
Why this matters for your business
Works everywhere
WordPress, Shopify, Squarespace, Wix, Webflow, custom HTML, React, Next.js, or any platform that lets you add a script tag. If you can edit HTML, you can deploy Brain Buddy.
Shadow DOM isolation
The chat widget runs inside Shadow DOM. Your website's styles don't leak into the widget. The widget's styles don't leak into your website. Zero CSS conflicts, guaranteed.
Async loading
The script loads asynchronously, meaning it doesn't block your page from rendering. Your website speed is unaffected. Core Web Vitals stay clean.
No plugins needed
No WordPress plugin to install, no Shopify app to configure, no third-party middleman. One script tag, pasted once, works forever.
How it works
Go to your chatbot settings in the Brain Buddy dashboard
Copy the embed script tag (one line of HTML)
Paste it into your website before the closing </body> tag
For WordPress: paste in Appearance > Theme Editor > footer.php or use a header/footer plugin
For Shopify: paste in Online Store > Themes > Edit Code > theme.liquid
Brian is live on your site immediately. No deployment, no build step, no waiting.

Learn about the Self-Learning EngineFrequently asked questions
Does it work with WordPress?
Yes. Paste the script tag into your theme's footer.php file, or use a header/footer plugin like Insert Headers and Footers. No WordPress-specific plugin needed.
Does it work with Shopify?
Yes. Go to Online Store > Themes > Edit Code > theme.liquid and paste the script tag before the closing </body> tag. Brain Buddy will appear on every page of your store.
Will it slow down my website?
No. The script loads asynchronously, which means it doesn't block your page from rendering. It has zero impact on your page speed scores and Core Web Vitals.
What is Shadow DOM and why does it matter?
Shadow DOM is a web standard that creates an isolated environment for the chat widget. Your website's CSS can't accidentally break the widget, and the widget's CSS can't accidentally change your website's layout. This eliminates the CSS conflict issues common with other chat widgets.
Can I deploy on multiple websites?
Yes. Each chatbot in your Brain Buddy account gets its own embed code. If you have multiple websites, create a chatbot for each one and deploy separately. The Pro plan includes 3 chatbots, Business includes 10.
