Stop losing customers to poor search results. AI Vector Search transforms your WooCommerce store’s search experience with intelligent, AI-powered technology that understands what your customers are really looking for – not just matching keywords.

Whether you run a small boutique or manage thousands of products, this plugin delivers lightning-fast, highly relevant search results that increase conversions and improve customer satisfaction.

🚀 Why AI Vector Search?

Traditional WooCommerce search fails when customers use different words, misspellings, or partial product codes. Our plugin solves this with three powerful search modes you can choose based on your needs:

Lite Mode (Default – Free Forever)
Works instantly after installation with zero configuration. Uses advanced TF-IDF algorithms with synonym expansion and stopword filtering. Perfect for stores under 1,000 products or budget-conscious merchants. No external services, APIs, or monthly costs required.

Self-Hosted Supabase Mode
Unlock enterprise-grade search on your own infrastructure. Get PostgreSQL full-text search combined with optional AI semantic understanding via OpenAI embeddings. Your data stays in your Supabase project – you maintain complete control. Includes partial SKU/EAN/UPC/ISBN matching, hybrid search strategies, and scales to millions of queries. Free tier supports 50,000 queries/month.

Managed API Service Mode
Let us handle everything. Simply activate with your license key and we manage the entire stack – Supabase hosting, OpenAI integration, infrastructure updates, scaling, and maintenance. You focus on your store, we handle the complex search infrastructure.

Developers seeking modern, scalable search infrastructure

🔒 Security & Transparency

Your Data, Your Control:
All API keys are encrypted in your WordPress database. Self-hosted mode keeps your product data in your own Supabase project. The Managed API mode processes your data securely in isolated environments. All communications use HTTPS/TLS encryption.

Transparent Pricing:
* Lite Mode: Free forever, runs locally
* Self-Hosted Supabase: Free tier includes 50,000 queries/month. Optional OpenAI embeddings cost ~$0.05-$1.00 per 1,000 products (one-time setup cost only)
* Managed API Service: Subscription-based pricing includes all infrastructure costs

No Data Lock-In:
You always maintain access to your product data. Switch modes or export your data anytime.

🏆 What Makes This Different?

Unlike other search plugins that require expensive third-party subscriptions or complex setups, AI Vector Search gives you complete flexibility. Start free with Lite Mode, upgrade to self-hosted infrastructure when you grow, or let us manage everything with the API service. You choose the approach that fits your business model and budget.

Built by developers for developers, with comprehensive documentation, WP-CLI support, and extensibility via WordPress hooks and filters.

📦 Installation

Quick Start (5 Minutes)

Install & Activate the plugin from WordPress admin or upload manually.
Use Lite Mode instantly – search works locally out of the box. Visit AI Vector Search -> Settings to adjust Lite stopwords, synonyms, or index limits if you need to tune results.
(Optional) Connect Supabase for self-hosted search:
- Create a free account at supabase.com and start a new project.
- Copy your project URL and service key into the plugin settings.
- Run the built-in schema installer from the admin UI or WP-CLI.
(Optional) Enable Semantic Search with OpenAI:
- Add your OpenAI API key to generate embeddings (self-hosted or API modes).
- Choose the search mode that fits your catalog and budget.
(Optional) Run a product sync from AI Vector Search -> Sync Products or with wp aivs sync-products when Supabase is connected.

Command Line Tools (WP-CLI)

Speed up setup and maintenance with new WP-CLI commands (requires the PostgreSQL client and, for schema installs, the encrypted connection string saved in settings):
* wp aivs install-schema – install or update the Supabase schema from your WordPress server.
* wp aivs check-schema – verify tables, functions, and extensions are present.
* wp aivs test-connection – confirm credentials before running migrations.
* wp aivs sync-products – batch sync products after catalog changes.

You can also trigger schema installation from the admin UI; both paths use the encrypted PostgreSQL connection string you store under Settings AI Supabase.

Getting Your API Keys

Supabase:
1. Visit app.supabase.com
2. Go to Project Settings API
3. Copy your project URL and service role key

OpenAI (Optional for Semantic Search):
1. Visit platform.openai.com/api-keys
2. Create a new API key
3. Ensure billing is set up for embedding API usage

❓ Frequently Asked Questions

What are the connection modes?

Lite mode runs locally and is enabled by default. Switch to self-hosted Supabase when you want scalable vector search on your own infrastructure, or activate the managed API service with your license key when you prefer a fully hosted stack. You can change modes in Settings AI Supabase and the plugin will guide you through any extra steps (keys, schema install, or product sync).

When should I use each connection mode?

Lite Mode – Best for: small stores (<1000 products), budget-conscious merchants, or testing the plugin
Self-Hosted Supabase – Best for: full control, larger catalogs, semantic search, international stores

Can I switch connection modes later?

Yes! You can switch between Lite, Self-Hosted, and Managed API modes at any time from Settings. Your search analytics are preserved, but you’ll need to re-sync products when switching to Supabase or API modes.

Is OpenAI required?

No! The plugin works great with just Supabase for fast keyword search. OpenAI is only needed for semantic (AI) search and enhanced recommendations. You can start with keyword search and add semantic features later.

How much does it cost to run?

Supabase: Free tier includes 50,000 monthly queries – perfect for most stores. Paid plans start at $25/month for high-traffic sites.

OpenAI: One-time embedding cost of ~$0.05-$1.00 per 1,000 products. After initial setup, ongoing costs are minimal (only for new products).

Will this slow down my site?

No! Search queries run on Supabase’s fast PostgreSQL infrastructure, not your WordPress server. This often makes search faster than default WooCommerce.

Does it work with my theme?

Yes! The plugin uses standard WordPress and WooCommerce hooks. It includes special integration for Woodmart theme’s live search feature.

Can I customize the search behavior?

Absolutely! The plugin is built with developer hooks and filters. Need custom field indexing or search logic? Check our Premium setup service for advanced customization.

What happens to my data if I uninstall?

Your product data remains in your Supabase project – you have full control. The WordPress plugin only removes its settings and stops syncing. You can delete data from Supabase manually if desired.

Is it GDPR compliant?

The plugin only syncs product data (names, descriptions, prices, etc.) – no personal customer information. When semantic search is enabled, product text is processed by OpenAI according to their privacy policy.

Can I use this on multiple stores?

Yes! Each store gets its own unique Store ID, allowing multiple WooCommerce sites to use the same Supabase project while keeping data separate.

How do I display cart recommendations?

You can show AI-powered recommendations based on cart contents using:
* Shortcode: [aivs_cart_recommendations] – Add anywhere in your content
* Gutenberg Block: Search for “Cart Recommendations” in the block editor
* Elementor Widget: Available in Elementor’s widget panel
* Template Function: for theme files

PHP: 8.0 or higher (8.1+ recommended)
