AI Support Assistant

AI Support Assistant lets you build an on-site chatbot that answers questions based on your actual documentation, product manuals, and guides.

Most AI chatbots either hallucinate or require you to pay monthly subscription fees for external vector databases like Pinecone, Qdrant, or Milvus. This plugin takes a different approach: it stores embeddings and runs similarity queries directly inside your existing WordPress MySQL database.

When a visitor types a question in the chat widget:
1. The plugin converts the question into an embedding vector.
2. It runs a cosine similarity search across your document chunks in MySQL.
3. It sends the best matching excerpts to your chosen AI model (Gemini or OpenAI).
4. The assistant replies using your content and shows which documents it referenced.

If the answer is not in your documents, you can set a fallback response so the bot does not make things up.

Main Highlights

• Self-contained vector search: Embeddings are saved directly in your WordPress database. You do not need any external vector database accounts or recurring SaaS fees.
• Works with Google Gemini and OpenAI: Use Gemini models (like Gemini 3.1 Flash Lite or 1.5 Flash) or OpenAI (like GPT-4o or GPT-4o-mini).
• WordPress AI Connectors support: Ready for WordPress core AI Client and Connectors API.
• File uploads: Upload PDF, Word (.docx), or plain text (.txt) files from your admin area. The plugin splits documents into searchable text chunks automatically.
• Document citations: Responses can display badges showing which uploaded file provided the answer.
• Customizable widget: Choose between Light, Dark, or Glass themes. Adjust widget height, width, title, and initial greeting.
• Usage insights and query logs: Review visitor questions, token usage, and response logs from the admin dashboard, with an option to export logs to CSV.

• Privacy first: Only the document text needed for an answer and the visitor’s question are sent to the AI API. Visitor IPs and personal WordPress user data are never sent.

External Services

This plugin connects to third-party AI APIs to generate embeddings and generate chat responses. Data is sent over HTTPS only when documents are indexed or when a user submits a chat message:

• OpenAI API (https://openai.com): Used for text embeddings and chat answers if OpenAI is selected. See the OpenAI Terms of Use (https://openai.com/policies/terms-of-use/) and Privacy Policy (https://openai.com/policies/privacy-policy/).
• Google Gemini API (https://ai.google.dev): Used for text embeddings and chat answers if Gemini is selected. See Google Terms of Service (https://developers.google.com/terms) and Privacy Policy (https://policies.google.com/privacy).
• WordPress AI Connectors: If enabled on WordPress 7.0+, connections route through credentials defined in your site settings.

No personal user data (like user accounts or IP addresses) is passed to these external services.

Requirements

• WordPress 6.2 or higher
• PHP 8.2 or higher
• MySQL 5.7+ or MariaDB 10.3+
• An API key from Google AI Studio (Gemini) or OpenAI
