<head>section and the web component to the<body>section of your website. Done!

How It Works Behind the Scenes
We've designed the widget to be both powerful and seamless. It relies on NeedleClient, a tool that talks to your Needle backend to pull in the data your users are searching for. Here's the core flow:
Search Query: When a user types a question, the widget sends it to Needle, which searches through your data to find relevant parts.
Response Generation: Based on the data, Needle generates a contextual answer and displays it in the widget.
User-Friendly Interface: Users interact through a simple floating button that opens the widget, allowing them to ask questions and get instant responses without any page reloads or additional clicks.
All of this happens in real time. Whether it's answering simple FAQs or handling more complex requests, the widget is designed to be fast and responsive.

The Technical Details (For the Curious)
If you're into the tech side, here's a brief rundown of how the widget is constructed.
The widget itself is a React-based component, which uses Needle SDK libraries to interface with Needle's powerful search engine. We export our code as Web Component, a powerful unifying standard supported by all major browsers to simplify integrating UI components into your website. It works whether your website is in React, Angular, Vue.js, Wordpress, Webflow, etc. you name it. Therefore Needle QA Widget has full compatibility.
We use @r2wc/react-to-web-component to convert our React code into Web Components standard. It works seamlessly off-the-shelf and we had very good experience using it! Kudos to the authors of the library 👏
One thing we had do differently when compared to developing a regular React app was packaging and delivery of the CSS styles. When developing a widget to be integrated in an external website, we must to isolate widget styles from the host website styles. For that purpose we used twind to allow using Tailwind in our widget code. Twind converts Tailwind classes into actual CSS rules at runtime with a minimal overhead.
See our packaging code below to get a gist of how we convert React components to Web Components.
import r2wc from "@r2wc/react-to-web-component";
import install from "@twind/with-web-components";
import config from "./twind.config";
import { AskQuestionWidget } from "./widgets/AskQuestionWidget";
const withTwind = install(config);
const AskQuestionWebComponent = withTwind(
r2wc(AskQuestionWidget, {
props: {
collectionId: "string",
clientKey: "string",
},
shadow: "open",
}),
);
customElements.define("needle-widget", AskQuestionWebComponent);Available SDKs for Deeper Integration

Summary
The Needle QA Widget brings AI-powered, content-grounded search to any website in under 5 minutes with a single embed snippet. Built as a Web Component with Shadow DOM isolation, it works seamlessly across React, Angular, Vue, WordPress, Webflow, and plain HTML without style conflicts. The widget delivers direct, contextual answers (not just page links) using Needle's semantic search engine, and supports natural language queries out of the box. For deeper integrations, Needle offers Python, Haystack, and HTTP API SDKs.
