Chatbot IO Widget is the official WordPress client for the bestchatbot.io service. It adds an AI-powered chat widget to your WordPress site. The widget uses your knowledge base to answer visitor questions, and can execute real actions like scheduling appointments, creating support tickets, and looking up orders.
Features: 
* AI chat widget powered by your knowledge base (RAG) 
* Identity verification for logged-in users (JWT-based) 
* WooCommerce integration: enriches identity with billing data and Stripe customer ID 
* Cache-safe: works with WP Rocket, W3 Total Cache, Cloudflare, and all page caching plugins 
* Zero friction for anonymous visitors (identity only required for protected actions)
How Identity Verification Works: 
1. The widget loads normally on all pages (no token in HTML) 
2. A background AJAX request checks if the visitor is logged in 
3. If logged in, a signed JWT token is generated server-side and passed to the widget 
4. The token enables protected actions (order lookup, subscription check, etc.)
This approach is cache-safe because the AJAX endpoint (admin-ajax.php) is never cached by WordPress caching plugins.
Third-Party Service: 
This plugin requires a bestchatbot.io account to function (SaaS). The widget connects to the bestchatbot.io service at https://bestchatbot.io to process conversations, run the knowledge base (RAG) pipeline, and execute tool calls. By installing this plugin you agree to the bestchatbot.io Terms of Service and Privacy Policy: https://bestchatbot.io/terms

<h4>Core Features</h4>
Your AI chatbot includes everything you need for customer support, lead generation, and engagement:
✅ Conversational Forms 
Your AI doesn’t just answer questions—it can run conversational forms when visitor intent matches your configuration: the chatbot collects standard fields through dialogue. You can also use widget forms—the type is chosen when you set up the form (conversational vs widget). Submissions are stored locally, and each new entry can be delivered by email or Slack.
✅ Quick 3-Step AI Chatbot Setup 
Guided wizard launches after activation. Connect your AI provider, configure personality, add knowledge sources, and customize appearance—live in under 5 minutes.
✅ Advanced AI Chatbot RAG Technology 
Train on unlimited WordPress content using Retrieval-Augmented Generation. Supports pages, posts, custom post types, PDFs, text files, rich text input, Q&A entries, and webpage content fetched from URLs. Intelligent intent recognition retrieves the most relevant knowledge for accurate responses. Auto-sync keeps WordPress knowledge sources (pages, posts, custom post types) automatically up to date—no manual re-training needed when content changes. Knowledge Filtering lets you accurately filter and view which sources are available in your knowledge base. AI Agent can also render images from learned sources (Beta) for richer, more visual responses.
✅ Transcripts 
View all chats, see which knowledge sources were used per reply, add missing Q&A entries, and review user context (guest/logged-in status and IP addresses).
✅ Cost-Optimized AI Usage 
Smart token management minimizes API charges. Intelligent request optimization ensures you pay only for what you need. Configure rate limits to control expenses.
✅ Streaming AI Responses 
Real-time word-by-word AI replies for faster, more natural conversations. Especially useful when short answers setting is disabled – long responses are printed naturally and quickly instead of making users wait for the full response to be ready.
✅ Customizable Chat Experience 
Unlimited widgets including Message Starters, Message Prompts, Chat History, Links, Lead Generation, and custom announcements. The Lead Generation widget collects user name and email before allowing conversation to start—so you know who is chatting and can follow up or add them to your leads list. Fully customizable greetings with emoji support. Simplified single-step widget publishing makes adding widgets effortless.
✅ Flexible Vector Storage 
Choose local WordPress database (free, unlimited) or Pinecone for enterprise-scale knowledge bases. Vector embeddings enable fast, contextually relevant retrieval.
✅ Complete Customization 
Customize colors, chatbot icon, AI avatar, chat box size, themes (light/dark/system), positioning, emojis, and greeting messages. Adapts seamlessly to all devices.
✅ Multi-Language Support 
Conversations in multiple languages with RTL compatibility. The AI chatbot responds in your visitors’ language.
✅ GDPR Compliant 
All conversation data stored locally on your WordPress site. You control data retention, export, and deletion policies.
