Truly free AI chatbot for WordPress – supports OpenAI, Gemini, and unlimited website knowledge. Add smart widgets, customize UI, and connect directly.

== Description ==

AI Chatbot by Limb makes your website interactive with an intelligent chatbot trained on your actual content.

**Use your own OpenAI or Gemini API key**, connect knowledge from pages, posts, custom post-type, PDF, txt or add manually via text editor. Fully control how your chatbot behaves and what it knows.

- **Multi-Provider Support**: Works with OpenAI, Gemini — more providers coming soon.
- **Widget of Interactive Items**: Add customizable widgets to the home screen, or chat screen. Each widget includes one or more item types like `prompt`, `chat history`, `link`, or `message`,

- **Appearance Customization**: Personalize the chatbot’s look to match your brand. Adjust colors, set greeting messages, and use emojis to add a friendly touch.
- **Conversation Starters**: Use prompt-type widgets to instantly launch predefined questions.
