<p>Geweb AI Search transforms your WordPress search into an intelligent assistant powered by Google Gemini AI. Instead of returning a plain list of matching posts, it understands the user’s question and provides a direct, contextual answer — along with links to the source pages.</p>
<p>The plugin intercepts the standard WordPress search form and opens a modal with two modes: instant autocomplete suggestions (via WP_Query) and a full AI chat powered by Google Gemini File Search.</p>
<h4>Key Features</h4>
<ul>
<li><strong>AI-Powered Answers</strong> — Uses Google Gemini File Search to find relevant content and generate natural-language answers</li>
<li><strong>Conversation History</strong> — Users can ask follow-up questions; the context is maintained across the session</li>
<li><strong>Source Attribution</strong> — Every AI answer includes links to the pages it was based on</li>
<li><strong>Instant Autocomplete</strong> — Traditional keyword search with live suggestions while typing</li>
<li><strong>Automatic Indexing</strong> — Posts are automatically uploaded to Gemini when published or updated</li>
<li><strong>Bulk Library Generation</strong> — Index all existing content with one click and a live progress indicator</li>
<li><strong>Multiple AI Models</strong> — Choose between Gemini 2.5 Flash, 2.5 Pro, and Gemini 3 models</li>
<li><strong>Multiple Post Types</strong> — Index any public post type: posts, pages, or custom post types</li>
<li><strong>Secure API Key Storage</strong> — API key is encrypted with libsodium before being stored in the database</li>
</ul>
<h4>How It Works</h4>
<ol>
<li>The plugin converts your WordPress posts to Markdown format (with URL and title in frontmatter)</li>
<li>Each document is uploaded to a Google Gemini File Search Store</li>
<li>When a user submits a search query, Gemini searches the indexed documents and generates an answer</li>
<li>The answer is displayed in a chat modal along with source links</li>
</ol>

<p>FindAstra is AI product search for WooCommerce. It helps your store understand what shoppers actually mean, not just the exact words they type. Someone searching for “comfortable shoes for hiking” will find your “Trail Running Sneakers” even when the title never mentions comfort or hiking.</p>
<p>Ordinary keyword search only matches products that literally contain the words a shopper types. So a customer who describes things in their own way lands on a “no results” page and leaves. FindAstra closes that gap. It reads the intent behind each search, puts the most relevant products first, and offers helpful suggestions instead of dead ends.</p>
<p>And the free version runs completely on its own. There are no API keys to paste, no account to create, and no monthly fees. The AI runs right inside the shopper’s browser, so nothing about your catalog or your customers is sent to an outside server, and you can index your entire catalog with no product limit.</p>
<h4>What your shoppers get</h4>
<ul>
<li><strong>Answers, not just matches.</strong> Searches are understood by meaning, so shoppers reach the right products even when their wording differs from yours.</li>
<li><strong>Live suggestions as they type.</strong> A search-as-you-type dropdown attaches to your existing search bar, with no theme editing.</li>
<li><strong>A results page that makes sense.</strong> Your normal WooCommerce results page is simply re-ordered by relevance, keeping your theme’s design exactly as it is.</li>
<li><strong>No more empty pages.</strong> When nothing is a strong match, shoppers see popular products instead of a dead end.</li>
</ul>
<h4>What you get as a store owner</h4>
<ul>
<li><strong>Set up in minutes.</strong> Activate, click index once, and AI search is live. No keys, no account, no configuration headaches.</li>
<li><strong>Private by default.</strong> Your products and your customers’ searches stay on your own site.</li>
<li><strong>Fits your store.</strong> Works with classic and block themes, and includes a search block, a shortcode, and a sidebar widget. Developers also get filter hooks and a REST endpoint to build on.</li>
</ul>
<h4>How it works, in plain terms</h4>
<p>When you click index, FindAstra reads each product and builds a small understanding of what it is. When a shopper searches, it compares their wording to that understanding and lists the closest products first. The first time it runs, the browser downloads a small AI model (about 33 MB) and reuses it from then on, so searches stay fast.</p>
<h4>FindAstra Pro (optional)</h4>
<p>A separate paid version is available at findastra.com for stores that want more. It adds optional server-side engines for very large catalogs (using your own OpenAI or Hugging Face key), multilingual search for WPML and Polylang, and built-in search analytics. The free version here is complete on its own, and nothing in it is locked or time limited.</p>
<h3>External services</h3>
<p>Which external service (if any) FindAstra contacts depends on the search engine you choose during setup. Each is described below, including what data is sent and when.</p>
<h4>Hugging Face model hub (huggingface.co)</h4>
<p>Used by the default <strong>Local</strong> engine. The first time the Local engine runs (when you index products in wp-admin, or when a shopper performs a search), the browser downloads a roughly 33 MB open-source AI model from the Hugging Face model hub and caches it locally for later visits. Only the model files are fetched. No store, product, shopper, or site data is ever sent. After the download, all search runs entirely in the browser.</p>
<p>Hugging Face terms of service: https://huggingface.co/terms-of-service . Privacy policy: https://huggingface.co/privacy</p>
<h4>OpenAI API (api.openai.com)</h4>
<p>Used only if you select the <strong>OpenAI</strong> engine and enter your own API key. At index time, the text of each product (its title and the fields you choose to include) is sent to OpenAI to generate an embedding; at search time, the shopper’s query text is sent. Requests are authenticated with the API key you provide and are made only while the OpenAI engine is the active provider.</p>
<p>OpenAI terms of use: https://openai.com/policies/terms-of-use . Privacy policy: https://openai.com/policies/privacy-policy</p>
<h4>Hugging Face Inference API (router.huggingface.co)</h4>
<p>Used only if you select the <strong>Hugging Face</strong> engine and enter your own access token. The same data as the OpenAI engine (product text at index time, query text at search time) is sent to the Hugging Face Inference API to generate embeddings, authenticated with the token you provide, and only while the Hugging Face engine is the active provider.</p>
