AI Chatbot from Your Site Content for WordPress – Answers Only from Your Pages, with Sources
A chat widget that answers visitors only from your own pages, posts and products, links its sources, says so when the site has no answer and hands over to a person, with rate limits and spending caps.
AI Chatbot from Your Site Content adds a chat button to your WordPress site. It answers visitors only from your own published pages, posts and products (WooCommerce is optional), shows the link of each page it used, and says “I could not find this on the site” when your pages have no answer, instead of guessing.
Honest by design
Passages of your content are found for each question; below the minimum match the AI is not even asked
An answer must name its sources, or it becomes the refusal
Links to other sites are removed; only your own pages are clickable
After a refusal: an e-mail form, a WhatsApp link or your contact page
Never reads what is not public
Drafts, private and password-protected items are never read, and an item that is unpublished or protected leaves the index at once. Exclude any item with one click.
Built for a public endpoint
Security token, hidden spam field, rate limits per visitor address and per conversation
Daily and monthly spending caps, with a friendly “chat unavailable” state
Prompt-injection hardening: visitor text and site content are data; obvious tricks are blocked; an answer that leaks the instructions is replaced
E-mail addresses and phone numbers are masked in the questions before they are sent
Tools for you
A test chat with the passages found and their match, a sources screen with batch reading and progress, and an optional log (off by default, masked, no IP, retention in days, export and delete) that lists the questions your pages do not answer.
Your AI account, your costs
Works with an OpenAI-compatible service (embeddings for search by meaning) or Anthropic (search by words). The key can live in wp-config.php. AI can be wrong: test before you open the chat to everyone.
Arabic, accessible, mobile friendly
A question in Arabic gets an answer in Arabic. The widget is keyboard operable, screen-reader friendly, right to left and mobile friendly, in your colour.
Tested
183 automated checks: retrieval, refusals, injection attempts, rate limits and caps, the visibility rules, the log and its retention, permissions, uninstall.

Frequently asked questions
Does it answer from the internet or from general AI knowledge?+
No. It is told to answer only from the passages of your site it is given, and an answer without a valid source is replaced by “I could not find this on the site”. An AI can still misread a passage, so test it in the test chat first.
Can it read my private pages or drafts?+
No. Only published items without a password are read; drafts, private and password-protected items, the cart and checkout pages are never read, and an item leaves the index as soon as it stops being public.
Do I need an AI account?+
Yes, your own: an OpenAI-compatible service (OpenAI, OpenRouter, Azure, a local server such as Ollama) or Anthropic. You pay your provider for what you use; the plugin has no usage fees. With Anthropic passages are found by words, as it has no embeddings.
How do I keep the cost under control?+
Set the daily and monthly spending caps, the rate limits and the longest question. Questions that match nothing are refused without asking the AI, and the same first question reuses its answer.
What happens when the chatbot cannot answer?+
It says so and offers an e-mail form, a WhatsApp link and your contact page, the ones you set up. Visitors can also press “Talk to a person” at any time.
Does it work with WooCommerce?+
Yes, optionally: products are read with their price, stock, SKU, categories and attributes, and the chat can be hidden on the cart, checkout and account pages. It does not show order status or act on the cart.
Does it work in Arabic?+
Yes. A question in Arabic gets an answer in Arabic, even from English pages. The widget, the administration and the guide are in Arabic and work right to left.
Is anything stored about visitors?+
Not by default. The optional log keeps the masked questions and answers with a scrambled conversation number, no IP address, for the days you choose. Rate limits use a salted hash of the address that expires within a day.
Can visitors trick it with “ignore your instructions”?+
The plugin reduces the risk: such questions are blocked before the AI (an option), visitor text and site content are passed as data, links to other sites are removed and an answer that leaks the instructions is replaced. No chatbot can promise to resist every trick.
