The AI chatbot that reads your website and answers the way you would.
SiteBrain indexes every page you publish, turns it into a structured business brain, and answers customer questions in your own voice — live in under two minutes.
Ships on anything you already run.
One script tag. Zero plugin drama. Your stack stays exactly the way it is.
Every answer is traceable to a page on your site.
SiteBrain isn't a vague AI assistant glued onto a textbox. It's a four-stage retrieval pipeline designed to ground every response in content you actually wrote.
Open-source crawler
Reads your sitemap, follows internal links, respects robots.txt. Extracts rich markdown with tables, FAQs, metadata — up to 100KB per build, boilerplate stripped automatically.
LLM-extracted business brain
A frontier model reads your entire crawl and extracts a structured profile — services, products, team, policies, FAQ, tone of voice — saved as typed JSON the chatbot reasons against.
{
"business": "acme.co",
"services": [6],
"products": [12],
"team": [4],
"faq": [12],
"tone": "confident"
}Grounded retrieval
OpenAI embeddings (1,536-dim) index every chunk. Each question runs cosine similarity across your content and returns the top 8 passages as grounding. No passage, no answer.
One-line embed
A single script tag drops the widget on your site — customizable colors, position, avatar, welcome message, behavior rules. Works on WordPress, Shopify, React, static HTML, anywhere.
<script
src="sitebrain.app/
widget.js"
data-sb-id="a1b2c3"
async
></script>Built for teams who are tired of chatbots that make things up.
Most chatbot builders give you a box. We give you a pipeline.
Grounded, not generated
Every reply is retrieved from your actual website content. If the source isn't there, SiteBrain says so — instead of inventing an answer.
Learns from one URL
Paste your domain. We handle the crawl, the chunking, the embeddings, the extraction. No training data to prepare, no intents to map, no flows to draw.

Still have questions?
SiteBrain is an AI chatbot platform that creates intelligent chatbots for your website. It crawls your site, learns your content, and answers customer questions 24/7 with accurate, context-aware responses.
Our free built-in crawler visits your website pages, extracts the content, and uses advanced AI to build a "business brain" — a structured understanding of your services, FAQs, contact details, and more. This knowledge powers your chatbot's responses.
SiteBrain uses RAG (Retrieval-Augmented Generation) to ground every answer in your actual content. If the bot doesn't find a relevant answer, it says so honestly instead of making things up. You can also customize behavior instructions to fine-tune how it responds.
Yes. Your website data is stored securely and only used to power your chatbot. We don't share your data with third parties or use it to train other models. You own your data, always.
The SiteBrain widget works on any website that supports JavaScript — WordPress, Shopify, Wix, Squarespace, Webflow, React, Vue, Next.js, and any HTML page. Just paste one line of code.
