Queryn – AI-powered Product Search for WooCommerce vs PDF Invoices & Packing Slips for WooCommerce

Queryn transforms the way customers search your WooCommerce store. Instead of typing exact product names or SKUs, shoppers can describe exactly what they want in plain language — and Queryn’s AI engine translates that into precise results in real time. Powered by the world’s leading AI providers (OpenAI, Google Gemini, and Anthropic Claude), Queryn intelligently parses natural-language queries into structured WooCommerce filters: categories, tags, product attributes, price ranges, and custom meta fields — all without touching a single line of template code. Video Overview “Show me red running shoes under $80” → Queryn automatically filters by color attribute, category, and max price. “Organic coffee beans above $20” → Queryn finds the right category and sets a minimum price filter. “Hello World” → Queryn finds your blog post titled Hello World alongside any matching products — normal search is never broken. Search Scope — Products, Posts, and Pages Together Queryn is smart about when to restrict results to products and when to search broadly: Filter-based queries (price, category, tags, attributes) always search WooCommerce products only, because those filters are product-specific. Keyword-only queries search across all post types you configure — products, blog posts, pages, and any custom post types — so shoppers never hit a dead end just because no product matches. You control exactly which post types are included in keyword searches from the Search Scope section on the General settings tab. WooCommerce products are always included and cannot be deselected. Apply AI Search On — Control API Costs The new Apply AI Search On setting lets you restrict when the AI engine is triggered: All search pages (default) — AI processes every search query site-wide. WooCommerce pages only — AI is triggered exclusively when a search is submitted from a WooCommerce page (shop, product categories, product tags). Searches from blog pages, contact pages, or any non-WooCommerce context skip the AI call entirely and fall back to standard WordPress search — saving API credits for queries that actually matter. Your existing WordPress search behaviour is fully preserved. Queryn only modifies the main search query when a valid AI provider is configured and active. If the API key is missing, the plugin is inactive, or the AI call fails, WordPress falls back to its standard search without any interference. Why Queryn? Higher Conversion Rates — Shoppers who find products faster buy more. Natural language search removes friction from the discovery process. Zero Configuration Required — Queryn reads your existing WooCommerce categories, tags, and attributes automatically. No mapping, no manual setup. No Broken Search — Keyword searches that don’t match any product will still surface blog posts, pages, and other content — shoppers are never shown an empty results page unnecessarily. Provider Flexibility — Switch between OpenAI, Google Gemini, and Anthropic Claude without losing your other API keys. Pre-configure all three and swap with one click. Smart Caching — AI responses are cached for one hour, dramatically reducing API usage and keeping your store fast. Privacy First — Only store taxonomy data (category names, tag names, attribute values) is sent to the AI. No customer PII, no order data. Supported AI Providers OpenAI The industry standard for conversational AI. Queryn supports GPT-4o, GPT-4o Mini, and GPT-4 Turbo — choose the model that best fits your budget and accuracy needs. Google Gemini Google’s multimodal AI family. Queryn supports Gemini 2.5 Pro, Gemini 2.5 Flash, and Gemini 2.5 Flash Lite. Gemini 2.5 Flash offers the best balance of speed, accuracy, and cost for most stores. Anthropic Claude Anthropic’s safety-focused models deliver outstanding instruction-following and structured output. Queryn supports Claude Sonnet 4.6, Claude Haiku 4.5, and Claude Opus 4.7. What Gets Filtered Queryn extracts the following from a shopper’s search query and applies them directly to WP_Query: Product Categories — mapped from your store’s product_cat taxonomy Product Tags — mapped from your store’s product_tag taxonomy Product Attributes — all pa_* attribute taxonomies (color, size, material, etc.) Price Range — minimum price, maximum price, a range, or an exact price (“priced at $15”) Custom Meta Fields — any public meta key registered on your products Keyword — the core product term extracted for text-based title matching (intent words like “show me” or “find” are automatically ignored) Privacy & Third-Party Services Queryn connects to the AI provider you configure. By enabling a provider, you agree to their terms of service and privacy policy: OpenAI: openai.com/policies/privacy-policy Google Gemini: policies.google.com/privacy Anthropic: anthropic.com/privacy Data sent to the provider consists solely of your store’s taxonomy structure (category names, tag names, attribute values, and public meta keys) and the shopper’s search query. No personal customer data, email addresses, or order information is ever transmitted.
