AI Search – Smarter WordPress Search That Understands Meaning vs Trill AI Product Chat for WooCommerce

Two things your site search is missing: instant results while typing, and an AI that understands what visitors mean. Drop in the AI Search Box block and your visitors see results the moment they start typing — thumbnail, title and price, right there in a dropdown. No page reload, no waiting. Then the part keyword search cannot do. Someone who types “summer blue dress” finds your “light cotton navy sundress”. Someone searching “headphones for running” finds your sweat-resistant wireless earbuds — even if the word “running” isn’t anywhere in the description. A reader looking for “how to reduce hosting costs” finds the article you titled “cutting your server bill in half”. WordPress search matches keywords. AI Search matches meaning. It reads your content — titles, descriptions, SKUs, categories, tags, attributes and custom fields — and converts each item into a vector that captures what it actually is. When someone searches, the plugin finds the closest matches by meaning, not by exact word overlap. The result: fewer empty search pages, more of your content surfaced for long-tail queries, and visitors who find what they wanted on the first try. Works on any WordPress site. Built with WooCommerce stores in mind — SKUs, variations, product attributes and catalog visibility are all handled properly — but the same search works for blog posts, pages, documentation, directories and any custom post type. 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 (new in 1.33.0) 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 request. A ten-character search uses one embedding, 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 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 users 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 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 fingerprint. The closest semantic 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. Embeddings are generated automatically when you publish or update products — no manual work after setup.

Trill AI Product Chat for WooCommerce — the AI shopping assistant that turns chat into measurable revenue. Trill AI Chat Lite adds a friendly, store-aware AI chat to your WooCommerce site in under 5 minutes. Robin — the AI assistant — answers shoppers in natural language using your real catalogue, your real page content, the current cart, and verified order data. The merchant gets a dashboard that proves revenue from chat. Free forever, open source, GDPR-ready. New in 2.4 — GDPR tools that usually sit behind a paywall, free GDPR Tools admin page. Look up everything the plugin holds for a visitor’s email, review it on screen, download it as JSON or CSV, or erase it permanently — with a typed DELETE confirmation so nothing is removed by accident. Audit trail. Every search, view, export and erase is recorded: who, when, and how many records. Emails are stored masked — and there is deliberately no IP column, because I never store IPs. Consent gate in the widget. Optionally require visitors to accept your privacy notice before chatting. Consent lives only in their browser and is re-requested automatically if you change the notice. “Request My Data” in the widget. Visitors can trigger a WordPress-native personal-data request straight from the chat footer, confirmed by email through WordPress core. Retention dashboard. See stored totals and your retention window at a glance, preview what a cleanup would delete, or run it on demand. New in 2.3 — resilient by design Reinstall without fear. Deleting and reinstalling the plugin now reconnects to Trill Cloud automatically — the plugin proves it controls your site and receives a fresh connection secret. Your plan and monthly usage are preserved. Small catalogues get real answers. “What do you sell?” now responds with your featured and latest products instead of coming up empty. Policy questions find the right policy. Answers draw from a wider variety of your pages — one snippet per page — so “what’s your refund policy?” surfaces the Refund page every time. An honest usage bar. The Monthly Usage panel shows your plan’s real allowance (50 free / 2,000 on Trill Cloud) and updates automatically when your plan changes. New in 2.2 — see every conversation New Conversations admin page. Browse every chat from a new Trill Chat → Conversations screen, with message count, average rating, conversion status and attributed revenue on every row. Filter and search. Narrow by date range, status and star rating, and search across message content to find any conversation fast. Read full transcripts. Open any conversation in a popup to read the complete back-and-forth, rendered as plain text. Export to CSV. Download the whole filtered list, or a single conversation’s transcript — exports are hardened against spreadsheet formula injection. Tidy up. Permanently delete conversations you no longer need, one at a time or in bulk. Why store owners pick Trill AI Chat over generic AI plugins WooCommerce-native, not bolted on. Understands products, variations, stock, categories, carts and orders out of the box — every code path is designed for e-commerce. 5-minute install. No API keys. No external account signup — your WordPress admin is the only login you need. Reads your real catalogue + your real pages. Real-time product search and page content indexing. Robin can answer “do you have red dresses?” and “what’s your return policy?” from the same conversation. Knows the cart. Robin sees what shoppers already added and helps them checkout instead of forgetting state. Privacy-first order lookup. Identity verified before any order detail is shared. WordPress login for registered customers, email-match for guests, silent fall-through on mismatch. Revenue attribution built in. Orders placed within 24h of a chat are tagged as “from chat” and surface on the dashboard with attributed revenue. Managed AI, predictable cost. Generous monthly conversation allowance on Trill Cloud. Track usage from the admin dashboard. No OpenAI account required. Topic-safe. Built-in guardrails auto-generated from your store metadata keep conversations about shopping, politely declining homework, code generation, medical or legal advice. Prompt-injection-protected. The assistant will not reveal system instructions or adopt different personas. GDPR-ready, with the tooling to prove it. UK-registered company (Greensolutions Pioneers Limited, Companies House 15693716). HTTPS end-to-end. Chat data is never used to train AI models.

Trill Cloud The free tier includes 50 conversations per month — plenty to see the value on a smaller store. Growing stores can upgrade to Trill Cloud (£12/month) for 2,000 conversations per month, longer AI responses and priority support. The upgrade is applied to your site’s existing connection — same plugin, no reinstall — and the dashboard usage bar reflects your new allowance automatically. See trillai.io/pricing. Built for WooCommerce, by a UK developer I build Trill AI at Greensolutions Pioneers Limited, a UK-registered company (Companies House 15693716). I focus exclusively on AI products for WooCommerce — not a generic chatbot with a Woo plugin bolted on. If you run a UK, US or EU store and want AI chat that respects your data, your time and your budget, I’d love to hear what you think.

No Composer dependencies, no external JavaScript libraries. External Services This plugin relies on Trill Cloud, the managed AI back-end I operate (Greensolutions Pioneers Limited), at https://api-v2.trillai.io, as its sole AI processing service. The service is required for the plugin to function. What data is sent, and when: When a store visitor sends a chat message, the message text and the WooCommerce context needed to answer it — product names, prices, descriptions and, where relevant to the question, the current cart contents and order-status details — are transmitted to Trill Cloud over HTTPS for AI processing. Each site authenticates with a per-site Bearer token (hashed at rest). Trill Cloud enforces the monthly conversation allowance server-side (no local trialware). No IP addresses are sent, and no customer personal data beyond what the visitor types into the chat and the catalogue context required to answer. Service links: Service URL: https://api-v2.trillai.io Terms of Service: https://trillai.io/terms-of-service/ Privacy Policy: https://trillai.io/privacy-policy/ No personal visitor data is collected or stored by Trill Cloud beyond what is strictly necessary to process each individual chat message. Chat data is never used to train AI models.
