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.

Key Features

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 Shoppers, Not Just Keywords: Semantic search means “cozy winter sweater” matches your “merino wool pullover”. Long-tail and descriptive queries stop returning empty pages.
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 shoppers never hit a zero-result page — if AI search finds nothing, standard WordPress search takes over automatically.
No OpenAI Account Required: Uses our free embedding service (up to 10,000 embeddings per site). Works out of the box for most stores.
Bring Your Own API Key: Optionally use your own OpenAI API key for unlimited indexing.
Bulk Embedding Generation: 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.

Perfect For

WooCommerce stores with large or varied product catalogs
Fashion & apparel stores where shoppers describe products in their own words (“something flowy for summer”)
Electronics & home goods stores with complex technical specs and model numbers
Books, media, and marketplaces with thousands of titles
International stores selling in multiple languages
Membership sites, knowledge bases, and directories — any content-heavy WordPress site

How It Works

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.
When a shopper types a search query, their query gets its own fingerprint in the same way.
The plugin compares the query’s fingerprint against every product’s fingerprint and returns the closest matches by meaning — not just by word overlap.
Results are ranked by relevance, so the products shoppers actually want appear first.
If no semantic matches pass the threshold, a 4-tier fallback kicks in so shoppers never hit an empty results page.

Embeddings are generated automatically when you publish or update products — no manual work after setup.
