Site-aware AI chat widget for WordPress with a crawlable knowledge base, optional OpenAI API key support, and free online fallback providers.

Description

WP AI Chat adds a configurable chat widget to your WordPress site. It can crawl published pages and posts into a local knowledge base, use that knowledge in prompts, and answer visitor questions through an optional OpenAI API key or free online fallback providers.

Features:

  • Crawl pages and posts into a local knowledge base.
  • Add custom facts or Q&A entries manually.
  • Train a site summary from the knowledge base.
  • Optional OpenAI embeddings for semantic search.
  • Optional OpenAI API key with encrypted storage.
  • AI modes: Free only, OpenAI with free fallback, or OpenAI only.
  • Free online fallback providers when no API key is configured or the primary provider fails.
  • Configurable widget design, placement, visibility, tone, language, and content rules.
  • Response caching with scheduled cleanup.
  • Public chat endpoint with IP-based rate limiting.
  • Optional attribution control, disabled by default.

Note: Crawled page content is injected into AI context. Only crawl content you trust, because adversarial text in site content can influence model behavior.

Installation

  1. Upload the wp-aichat folder to /wp-content/plugins/.
  2. Activate WP AI Chat from the Plugins screen.
  3. Open AI Chat > AI Configuration to configure provider behavior.
  4. Open AI Chat > Knowledge Base and run a crawl.
  5. Adjust widget design and placement as needed.

Frequently Asked Questions

Do I need an API key?

No. The plugin includes free online fallback providers. For more reliable 24/7 responses, add an OpenAI API key in AI Chat > AI Configuration.

Is the API key exposed to visitors?

No. API keys are stored server-side, encrypted at rest where OpenSSL is available, and are never sent to frontend JavaScript.

Does it crawl WooCommerce products?

No. Product crawling is intentionally excluded.
