About this plugin
Help shoppers find suitable WooCommerce products using everyday-language requests. The free Product Finder searches local product information and can recommend actual catalogue items without an AI subscription or API key. Matching depends on merchant-maintained product data and discovery keywords; optional AI features are available separately.

Precise Expressions Product Fit Assistant for WooCommerce adds a compact slide-out assistant to single product pages. It helps shoppers review fit, compatibility, product options, accessories, personalization details, and ordering checks before checkout without crowding the product page.
The assistant is rule-based by default and uses WooCommerce product data, global templates, category guidance, attribute guidance, product attributes, variations, upsells, cross-sells, and optional merchant notes. Prompt buttons are selected from product context, and merchants can add custom help prompts for individual products.
For products configured for suitability assessment, merchants can define deterministic product rules, variation viewing-distance ranges, and authoritative variation display-method facts. Shoppers answer guided questions and the server evaluates the configured data deterministically. For size or option-choice prompts, the assistant can compare purchasable variations and present tied suitable options without changing the shopper’s selected variation.
The plugin also includes Product Finder, a store-wide product discovery assistant available with the [pfwa_product_finder] shortcode. Product Finder searches the local catalog first, recommends real published WooCommerce products, and falls back to local catalog search when AI is unavailable.
The deterministic rule-based guidance, suitability scoring, and cross-variation recommendations work without external services, subscriptions, or AI. Optional AI answers are available for merchants who connect their own OpenAI API account. The plugin is translation-ready, and AI-generated answers or discovery keyword suggestions can be instructed to use the site language, shopper language where possible, English (US), or a custom language.
The assistant and Product Finder provide merchant-configured guidance and product-data reminders. They do not guarantee fit, compatibility, product suitability, availability, or return eligibility.
Features include:
- Compact product-page slide-out guidance helper with context-aware prompt buttons.
- Deterministic suitability assessment using configured product rules and variation facts.
- Variation-specific viewing-distance ranges and authoritative display-method facts.
- Guided multi-turn suitability questions for configured shopper inputs.
- Deterministic cross-variation recommendations for size and option-choice prompts, including tied suitable options.
- Storefront rendering of configured suitability recommendations without automatic variation selection.
- Optional product-specific custom help prompts and personalization capability notes.
- Curated & Controlled Prompts: Add product-specific custom help prompts alongside context-aware suggested questions, keeping customer guidance focused on product discovery and purchasing decisions rather than open-ended AI conversations.
- Attribute & Taxonomy-Aware Product Discovery: Go beyond product titles and descriptions. Product Finder uses WooCommerce categories, tags, product attributes and merchant-defined discovery keywords to help match natural-language searches against real catalogue products.
- Relevance-Focused Results: No invented products or arbitrary catalogue filler. Product Finder scores real WooCommerce products, rejects zero-relevance candidates and applies additional relevance checks to reduce unsuitable recommendations.
- Product Finder shortcode for store-wide product discovery.
- Local candidate product search before optional AI ranking.
- Setup Guide with safe suggested global templates for common store types.
- Category and attribute guidance rules to reduce per-product setup.
- Global guidance templates for common reminders.
- Product-level fit notes, compatibility warnings, required accessories, common questions, and return-prevention notes.
- Primary, secondary, and exclude Product discovery keywords to improve Product Finder matches for natural shopper requests.
- Per-product Generate discovery keywords helper with Conservative, Balanced, and Broad styles, local suggestions, and optional AI suggestions.
- Optional privacy-minimal interaction logging.
- Simple dashboard to find products with weak or missing guidance.
- Optional AI-generated answers using a merchant-provided OpenAI API key.
- Basic language controls for AI-generated answers and Product discovery keyword suggestions.
- Temporary AI answer caching, usage limits, manual cache clearing, cache versioning, and scheduled cleanup.
- Privacy policy suggestion text.

Privacy
If interaction logging is enabled, Precise Expressions Product Fit Assistant for WooCommerce may store privacy-minimal assistant interaction logs. These logs may include product ID, selected prompt, optional shopper-entered question, whether guidance was available, and the interaction time.
Category guidance rules and attribute guidance rules are merchant configuration only. They do not store shopper identity or customer personal data.
The plugin does not intentionally store customer names, email addresses, billing addresses, shipping addresses, raw IP addresses, payment details, user agents, or full cart contents.
Guided suitability answers are held in browser session storage for the current tab and sent to the site to calculate deterministic guidance. Server-derived candidate scores, variation facts, and recommendations are not persisted as shopper state.
AI-generated answers are optional. The rule-based fallback can work without AI. If AI features are enabled, product context, shopper-entered questions or guided answers, Product Finder requests, limited candidate product information, one-product keyword-generation context, and configured language instructions may be sent to the selected AI provider.
The plugin searches the local WooCommerce catalog first and does not intentionally send the entire catalog.
AI answers and AI Product Finder recommendations may be cached temporarily to reduce repeated API calls and improve response speed. Cached entries do not include API keys and should not intentionally include customer personal data. Store owners can clear the AI answer cache from WooCommerce > Product Fit Assistant > AI Assistant.
Store owners should review shopper-entered questions before enabling logging or AI-generated answers and update their privacy policy as appropriate.
External Services
The rule-based fallback does not require external services.
If AI-generated answers are enabled, the plugin can connect to the OpenAI API from the server side. com/v1/responses for connection tests, optional product-page AI answers, optional AI-ranked Product Finder recommendations, and optional per-product Product discovery keyword suggestions.
Product context, merchant-entered personalization capability notes, shopper-entered questions or guided answers, shopper Product Finder requests, limited candidate product information, and one-product admin keyword-generation context may be sent to OpenAI when AI features are enabled.
