About this tool.
My Observer AI Shopping Assistant adds a chat box to your WooCommerce store. Shoppers ask questions in plain language (“Which of these is waterproof?”, “What do you have under $50 for a gift?”) and get answers based on your own products and the documents you upload, not on guesses from the internet.
How it works for you, the store owner:
Search is free. Finding the right products for a question works through MyObserver at no cost. You connect it with one click in the plugin settings.
Chat uses your own AI key. Answers are written by OpenAI or Claude using an API key from your own account, so you pay the AI provider directly. With gpt-4o-mini that is about $1 per 1,000 chats.
You stay in control. Choose the provider and model, cap how long answers can be, and limit how many messages one visitor or your whole site can send.
It never breaks. If smart search is not connected, or the service is busy, the chat falls back to normal keyword search of your catalog for that question.
This plugin is designed for merchants who want: * Product-aware chat that can reference your catalog content * Optional document-aware answers (shipping, sizing, care guides) linked to WooCommerce products * A simple setup flow inside wp-admin * Protection against runaway AI costs (answer length cap and message limits) * A choice of OpenAI or Claude for the chat answers
How it works at a high level: 1. Your WooCommerce products are indexed. The text is turned into search vectors by the MyObserver search service (after you click Connect) and stored on your own site. 2. Optional TXT, CSV, DOCX, and text-based PDF files can be uploaded into the Product Intelligence Engine. 3. A shopper’s question is matched against your products and documents. 4. Your chosen AI provider (OpenAI or Claude, with your own key) writes the final answer from what was found.
The storefront chat widget can be embedded with a shortcode or auto-injected in the footer, and the admin experience includes a modern settings screen for provider settings, limits and document management.

External services
This plugin can connect to third-party services based on your configuration.
01OpenAI API ( https://api.openai.com )
* Used for: chat answers when OpenAI is selected as the chat provider, and for listing the models available to your key. * Data sent: your OpenAI API key (to OpenAI only) and the shopper’s question with the product and document context needed to write the answer. * Terms of Use: https://openai.com/policies/terms-of-use/ * Privacy Policy: https://openai.com/policies/privacy-policy/
02Anthropic API ( https://api.anthropic.com )
* Used for: chat answers when Claude is selected as the chat provider, and for listing the models available to your key. * Data sent: your Claude API key (to Anthropic only) and the shopper’s question with the product and document context needed to write the answer. * Terms: https://www.anthropic.com/legal/commercial-terms * Privacy Policy: https://www.anthropic.com/legal/privacy
03MyObserver API ( https://api.myobserver.io )
* Used for: free smart search. It runs only after an administrator clicks Connect in the plugin settings; until then nothing is sent and the site uses keyword search. * Data sent when connecting: the site URL, the administrator email address and the plugin version. To prove you own the site, the service fetches a one-time code from /wp-json/myobserver-rag/v1/search-verify on your site; that route returns nothing except for a code that is valid for a few minutes. * Data sent afterwards: product text, document text and shopper questions, so the service can turn them into search vectors. Your OpenAI or Claude key is never sent to MyObserver. * Once a day while connected the plugin also checks the connection status and your daily usage. * Terms: https://myobserver.io/terms * Privacy Policy: https://myobserver.io/privacy
Privacy
Review the included privacy policy template and update site policy text as needed for your deployment. Chat rate limiting uses a one-way hash of the visitor’s connection address with a site-specific salt; the address itself is never stored.

Frequently asked questions.
Does this plugin require WooCommerce?
Yes. WooCommerce must be installed and active.
Do I have to connect to MyObserver?
No. Until you click Connect, nothing is sent to MyObserver and your store uses keyword search of your catalog. Connecting turns on smart search, which understands what the shopper means rather than only matching words.
What does it cost?
Smart search through MyObserver is free. Chat answers are paid to OpenAI or Anthropic with your own key. With gpt-4o-mini that is about $1 per 1,000 chats. You can limit answer length and the number of messages per visitor and per site.
Is my OpenAI or Claude key shared with MyObserver?
No. Your key is used only to talk to api.openai.com (OpenAI) or api.anthropic.com (Claude). It is never sent to MyObserver or anywhere else.
Can I place the chat widget manually?
Yes. Use [myobserver_rag_widget] (or legacy [rag_bot_widget] ) in any page, post, or block shortcode element.
Is product indexing automatic?
Once smart search is connected, edited products are queued automatically via WP Cron. You can also run a full “Rebuild index” from My Observer > RAG for WooCommerce .
I updated from an older version. Do I need to do anything?
If your search index was built with OpenAI’s text-embedding-3-small model (the default), it keeps working and you only need to click Connect. If it was built with any other model, or with the old Claude embeddings setting, the settings screen tells you to connect and rebuild the index. Until then your store uses keyword search.
Why does Connect fail with an ownership check error?
MyObserver confirms you own the site by fetching a short-lived code from /wp-json/myobserver-rag/v1/search-verify on your site. This fails on local or staging sites that are not reachable from the internet, when a security plugin blocks the WordPress REST API, or when a firewall blocks the request.
Can I upload documents to improve retrieval?
Yes. The Product Intelligence Engine lets you upload TXT, CSV, DOCX, and text-based PDF files, review them in the admin queue, and link them to WooCommerce products.
Does this plugin include payment or subscription checkout by itself?
Core storefront assistant functionality is in this plugin. Optional advanced add-ons are provided separately.
Does this plugin require an external vector database?
No. It uses a high-performance, file-based embedded vector database written in native PHP, separate from your MySQL database.
