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.

Love the idea and the implementation. I'll be using this more and more on all of our Woo sites.

ICON SL – Smart AI Search adds an advanced semantic search experience to WordPress websites.
Without an API key, searches fall back to the default local WordPress search behavior. To use Smart AI Search as intended, connect your ICON SL API key so the plugin can index public site content and return AI-powered semantic results.
<ul>
<li>Clean admin page focused on search behavior, usage, and maintenance tasks.</li>
<li>Shortcode <code>[iconslsas_search]</code> to show the Smart AI Search interface on any page.</li>
<li>Optional integration to use the Smart AI Search page as the default WordPress search experience.</li>
<li>Connect an API key to enable semantic indexing and AI-powered search results.</li>
<li>Local/classic WordPress search remains available as the fallback when the API key is not configured or semantic search is unavailable.</li>
<li>Semantic indexing keeps AI results in sync with your published content after the service is connected.</li>
</ul>
<h3>External Services</h3>
This plugin connects to ICON SL services to provide account management, setup, usage information, indexing, and AI-powered semantic search results. Without this connection, the plugin falls back to local WordPress search.
Service provider: 
ICON SL, https://iconsl.com/
When connected, the service indexes only public, published, searchable site content and processes search queries so semantic results can be shown to visitors. Without an API key, searches are handled locally by WordPress and the external service is not used for visitor search queries.
Data sent to this service:
<ul>
<li>Search queries — When semantic search is enabled with an API key, visitor search text is sent to retrieve relevant results. Results are filtered again in WordPress before display so only currently public/searchable posts can be returned.</li>
<li>Connection details — The saved account connection and site identity are used to authenticate the site with the service.</li>
<li>Public content data — Public post titles, content, URLs, modification dates, and related indexing information may be sent to build or refresh the semantic search index. Private, draft, pending, future, trashed, auto-draft, password-protected, and non-public/non-searchable post types are excluded.</li>
<li>PDF attachment data — PDF files are uploaded only when the attachment is public/searchable or attached to public searchable content. Private/protected media, uploads attached to private/draft/password-protected content, and local server file paths are not sent.</li>
<li>Index cleanup data — When indexed content is deleted or is no longer public/searchable, the plugin asks the service to remove stale semantic index records.</li>
<li>Usage/account data — When an administrator loads usage information or updates settings, the plugin may send the saved connection, site identity, and relevant non-secret search configuration values.</li>
</ul>
This plugin does not send database credentials, admin-only settings, private metadata, account keys in frontend JavaScript, or personal data about site visitors to the external service. When semantic search is enabled, only the search query text is transmitted for each visitor search.
Smart AI Search website and dashboard
The admin screen links to the Smart AI Search website so administrators can connect the service and manage their plan. These links are opened only when an administrator clicks them. WordPress sends the normal browser request data for a clicked external link, such as IP address, browser user agent, and referring page, according to the external site’s own policies.
