AI Search for WooCommerce
AI Search replaces WordPress and WooCommerce default search with AI that understands meaning, not just words. When shoppers search for “summer wedding dress”, “cozy winter sweater” or “outfit for a first date”, they find your products — even when none of those exact words appear in the title. Same store, same theme, same checkout. Nothing new for visitors to learn, nothing to configure to go live. Same queries with AI Search, products found: ✅ “summer wedding guest dress” → Light midi wraps, pastel jumpsuits, formal linen sets ✅ “warm cotton sweater for winter” → Merino pullovers, cable knits, cashmere blends ✅ “outfit for a first date” → Blazers, tailored dresses, leather boots ✅ “cozy loungewear for weekends” → Oversized hoodies, joggers, cotton sweatpants ✅ “wireless headphones for running” → Sweat-resistant earbuds, sport-fit models Not just WooCommerce. AI Search works on any WordPress site: blog posts, pages, documentation, directories, any public custom post type. Wherever visitors search, semantic matching finds what they meant. Try it live before installing: wp-search.ai/demos runs this exact plugin on three sample stores. Type your own search, or a SKU, and see the traditional results next to the AI results, side by side: Clothing store – users describe an occasion, not a product name Bookstore – readers remember the theme, never the exact title Electronics – model codes and specs, where exact SKU matching has to win Live search dropdown – type in the box and watch results appear before you finish Traditional Results First, AI Results After AI Search never replaces the results your search already finds. It adds to them. Every search runs in three steps, in this order: Exact matches: a query that matches a product SKU or an exact product title is always the first result. Traditional keyword results: everything WordPress and WooCommerce search would normally find (products literally containing your search words) comes next, ranked by keyword relevance instead of publish date. AI results: only below those. Semantic matches are added: products that mean the same thing even when they use different words. So if a user searches for something that literally exists on your site, they see exactly what they would see without the plugin, just better ordered. The AI layer only ever extends the results with products the traditional search missed. Installing AI Search will not change or hide the results your customers already find today. Search As You Type Two optional blocks bring live results to your site, without sending your visitors to a results page first: AI Search Box: a search field that shows results in a dropdown as the user types: thumbnail, product title and price on a single row. AI Search Button: a search icon for your header or menu that opens a full-screen search overlay. Both are Gutenberg blocks. Open any page, template or header in the editor, click the + button, search for “AI Search”, and place the one you want – there is nothing to configure to get started. They follow the same “traditional first” rule as the results page: keyword and SKU matches appear instantly on every keystroke, and AI suggestions are added underneath when typing pauses. Try the live search demo – three real catalogues, type anything you like. This keeps your quota intact. Keystrokes cost nothing, only the pause triggers a single AI lookup. A ten-character search runs one AI request, not ten. Both blocks read your theme’s own colours, fonts and corner radius, so they look like part of your site rather than something bolted on, on light and dark themes alike. They are fully keyboard and screen-reader accessible. And they are entirely optional: place one where you want it, or place none and nothing about your site changes. Key Features Search As You Type: Optional search box and search button blocks with a live results dropdown, keyword matches instantly, AI suggestions on pause. 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. Understands Meaning, Not Just Keywords: Semantic search means “cozy winter sweater” matches your “merino wool pullover”. Long-tail and descriptive queries stop returning empty pages. Traditional Results Are Never Lost: Keyword matches always rank above AI suggestions. The AI extends your search results. It never replaces them. 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. SKU & Attribute Matching: Customers can search by SKU fragments, attribute values, or technical specs and still find the right product. Smart Fallback System: 4-tier fallback ensures users never hit a zero-result page, if AI search finds nothing, standard WordPress search takes over automatically. No External Account Needed: Our free service covers up to 10,000 products per site, out of the box. Advanced: Use Your Own Provider Key: Power users can bring their own provider key for unlimited indexing. One-Click Indexing: Index your entire existing catalog in one click, filtered by post type or category. Quota Management: Real-time monitoring of AI service usage and limits (v1.14.0+). Works Beyond Products Too: Same intelligent search for blog posts, pages, and any public custom post type. ACF Compatible: Index Advanced Custom Fields data for deeper product metadata search. Tunable Similarity Threshold: Fine-tune how strict or broad search results are, per store. Intelligent Caching: Fast results with automatic local caching. AI Search Works With Any WooCommerce Store Fashion & apparel: “something flowy for a summer wedding” finds dresses; attribute-aware queries like “cotton breathable large” match by size and material Beauty & skincare: “my skin looks tired” finds night creams and recovery oils; “gift for sensitive skin” finds hypoallergenic sets Electronics: “wireless headphones for running” finds sweat-resistant earbuds; exact SKUs like WOO-HOOD-24 are always pinned first, no guessing Home & garden: “cozy living room” finds rugs, lamps, throw pillows; “durable outdoor” finds weather-resistant furniture Food & beverage: “healthy snacks for kids” finds low-sugar options across your catalogue Books & media: readers remember themes, plots and moods, rarely exact titles: “coming-of-age novel set in Japan” finds what keyword search never would B2B & wholesale: semantic queries like “cotton shirts bulk order” work the same way; your existing WooCommerce pricing rules and role-based visibility still apply Knowledge bases & directories: long-tail help queries stop hitting empty pages; “how to reduce hosting costs” finds “cutting your server bill in half” Works With The Plugins Your Store Already Uses WooCommerce: products, variations, virtual products, categories, tags, brand taxonomy, product attributes (size, color, material, etc.) ACF (Free and Pro): text, textarea, WYSIWYG, repeaters, and group fields; opt-in via the Custom Fields tab Meta Box, Pods, JetEngine: text fields exposed through standard WordPress meta APIs are picked up automatically; more via the ai_search_embedding_content filter WPML and Polylang: content is indexed separately per language, so a Portuguese query finds Portuguese products, not the English original Page builders: Gutenberg native. Elementor, Divi, Beaver Builder and Bricks content is indexed wherever it lands in post_content Any WordPress theme: the plugin extends your existing search template; no theme changes needed How It Works Each product in your WooCommerce catalog is converted into a “meaning fingerprint” that captures its title, description, SKU, categories, tags, and attributes. When a user searches, the plugin first pins exact SKU/title matches, then lists every traditional keyword match (what your search finds today), ranked by relevance. The query then gets its own meaning fingerprint, which is compared against every product’s. The closest meaning matches are appended below the traditional results, extra products the keyword search missed, never replacements for it. If nothing at all is found, a multi-tier fallback kicks in so users never hit an empty results page. Indexing happens automatically when you publish or update products, no manual work after setup.
