AI Search for WooCommerce makes your store’s search actually work. When a shopper types “summer blue dress” they find your “light cotton navy sundress”. When they search “headphones for running” they find your sweat-resistant wireless earbuds — even if the word “running” isn’t anywhere in the product description.
Default WooCommerce search matches keywords. AI Search matches meaning. It reads your entire product catalog — titles, descriptions, SKUs, categories, tags, and attributes — and converts each product into a vector that captures what it actually is. When a shopper searches, the plugin finds the closest matches by meaning, not by exact word overlap.
The result: fewer empty search pages, more products surfaced for long-tail queries, and shoppers who find what they wanted on the first try.
Also works with blog posts, pages, and any custom post type — so you can use the same intelligent search across your whole site.
<h3>Key Features</h3>
<ul>
<li>WooCommerce Product Search: Full product catalog indexing — titles, short and long descriptions, SKUs, categories, tags, and product attributes (size, color, material, etc.). Pre-configured defaults so you can go live in minutes.</li>
<li>Understands Shoppers, Not Just Keywords: Semantic search means “cozy winter sweater” matches your “merino wool pullover”. Long-tail and descriptive queries stop returning empty pages.</li>
<li>Cross-Lingual & Multilingual: Works with 100+ languages — Portuguese, Spanish, French, German, Greek, Arabic, Chinese, Japanese, and more. International stores get consistent search quality across every language, and an English query can still match content in other languages.</li>
<li>SKU & Attribute Matching: Customers can search by SKU fragments, attribute values, or technical specs and still find the right product.</li>
<li>Smart Fallback System: 4-tier fallback ensures shoppers never hit a zero-result page — if AI search finds nothing, standard WordPress search takes over automatically.</li>
<li>No OpenAI Account Required: Uses our free embedding service (up to 10,000 embeddings per site). Works out of the box for most stores.</li>
<li>Bring Your Own API Key: Optionally use your own OpenAI API key for unlimited indexing.</li>
<li>Bulk Embedding Generation: Index your entire existing catalog in one click, filtered by post type or category.</li>
<li>Quota Management: Real-time monitoring of AI service usage and limits (v1.14.0+).</li>
<li>Works Beyond Products Too: Same intelligent search for blog posts, pages, and any public custom post type.</li>
<li>ACF Compatible: Index Advanced Custom Fields data for deeper product metadata search.</li>
<li>Tunable Similarity Threshold: Fine-tune how strict or broad search results are, per store.</li>
<li>Intelligent Caching: Fast results with automatic local caching.</li>
</ul>
<h3>Perfect For</h3>
<ul>
<li>WooCommerce stores with large or varied product catalogs</li>
<li>Fashion & apparel stores where shoppers describe products in their own words (“something flowy for summer”)</li>
<li>Electronics & home goods stores with complex technical specs and model numbers</li>
<li>Books, media, and marketplaces with thousands of titles</li>
<li>International stores selling in multiple languages</li>
<li>Membership sites, knowledge bases, and directories — any content-heavy WordPress site</li>
</ul>
<h3>How It Works</h3>
<ol>
<li>Each product in your WooCommerce catalog is converted into a numeric “meaning fingerprint” (called an embedding) that captures its title, description, SKU, categories, tags, and attributes.</li>
<li>When a shopper types a search query, their query gets its own fingerprint in the same way.</li>
<li>The plugin compares the query’s fingerprint against every product’s fingerprint and returns the closest matches by meaning — not just by word overlap.</li>
<li>Results are ranked by relevance, so the products shoppers actually want appear first.</li>
<li>If no semantic matches pass the threshold, a 4-tier fallback kicks in so shoppers never hit an empty results page.</li>
</ol>
Embeddings are generated automatically when you publish or update products — no manual work after setup.

Whether you need a conversational chatbot to provide customer support, or a smart informational search engine to help users explore your site’s content, UZ AI Search adapts completely to your needs. It allows your website visitors to find precise answers based exclusively on your own indexed content (posts, pages, products, and custom post types), utilizing OpenAI technology.
Key Features: 
* Versatile Use Cases: Configure the AI as a friendly customer service assistant or a strict knowledge base search.

Important: The AI search assistant will respond in the language you specify in its prompt instructions. Please note that the default instructions are currently in Spanish. If you want the AI to answer in English (or any other language), you simply need to translate or adjust the instructions in the plugin’s settings.
