Instead of generic AI answers, the chatbot responds using your own content — including FAQs, product documentation, help articles, policies, and manuals. This makes it ideal for customer support, knowledge bases, SaaS onboarding, and eCommerce support automation. With Papaya Assist, you can deploy a fully functional AI support chatbot in minutes— no coding, no training models, and no complex setup required. The chatbot appears as a floating chat widget on every page of your WordPress site and works seamlessly on desktop and mobile. **Key Features:** * AI chatbot for WordPress powered by OpenAI and RAG * Upload documents (PDF, DOCX, TXT) to build your knowledge base * Automatic AI customer support based on your website content * One-click setup from WordPress admin (no external setup required) * Fully customizable chat widget (colors, title, branding) * Real-time streaming AI responses for natural conversation experience * Secure document processing with vector search (Pinecone) * Mobile-friendly chat widget with fullscreen mobile mode * Lightweight frontend — no heavy CSS or JS libraries * Works with most WordPress themes and caching plugins **How It Works:** 1. Install and activate Papaya Assist 2. Sign up or log in from your WordPress dashboard 3. Upload your documents (FAQ, guides, manuals, policies) 4.
