DeveloperAI-powered chatbot using RAG. Upload documents and let the AI answer visitor questions based on your specific knowledge base.
Papaya Assist adds an AI-powered chat widget to your WordPress site that answers visitor questions based on your own documents. Instead of generic AI responses, the chatbot uses Retrieval-Augmented Generation (RAG) to ground every answer in the content you provide — product guides, FAQs, policy documents, or any other material your visitors need.
Upload your files, click a button to process them, and the widget is live. No coding required, no theme edits, and no shortcodes to place. The chat bubble appears in the corner of every page and works on both desktop and mobile.
Features:
- One-click sign-up from within WordPress admin — no separate registration site
- Embeddable chat widget with customizable color and title
- Document upload and management (PDF, DOCX, TXT) directly from your dashboard
- Real-time streaming responses so visitors see answers as they are generated
- Shadow DOM isolation — the widget will not conflict with your theme styles or CSS
- Mobile-responsive design that switches to fullscreen on small screens
- Lightweight: no external CSS or JavaScript libraries loaded on your frontend
How It Works:
- Sign up or log in from the plugin settings page.
- Upload your documents (PDF, DOCX, or TXT) and click “Process Documents.”
- The chatbot answers visitor questions using RAG based on your documents — no training or fine-tuning needed.
