AI Chatbot Free Models – Customer Support, Live Chat, Virtual Assistant vs MxChat – AI Chatbot & Content Generation for WordPress

Important Notice for Users Updating to Version 1.6.6+ The latest update improves the plugin’s file structure for better performance. As a result, the default paths for some images (like the chatbot icon and avatars) have changed. If you notice that the chatbot button or avatars are not appearing after the update, it is almost certainly due to your browser or website’s cache. Solution: Please perform a “hard refresh” in your browser (Ctrl+F5 on Windows/Linux, Cmd+Shift+R on Mac). If you use a caching plugin (like WP Rocket, LiteSpeed, WP Fastest Cache etc.), please purge all caches from your plugin’s settings. This will solve the issue. AI Chatbot Free Models empowers you to integrate a cutting-edge AI chatbot into your WordPress website! Unlock the potential of over 400 AI models through OpenRouter.ai, including industry-leading options like ChatGPT, Claude, Grok 4 and Google Gemini 2.5 Pro, as well as powerful open-source alternatives such as Llama, Mistral, and DeepSeek! Choose from a wide array of both free and premium models to perfectly match your needs and budget. Unlike many other plugins, all management and customization happen entirely within your WordPress backend, no need to visit external sites for configuration. The only account required is to obtain your free API key. Looking for a platform-independent version? This chatbot is also available as a standalone version for use in non-WordPress websites (HTML, PHP, etc.). Get it on GitHub Use Cases Here are several practical ways to use Chatbot AI Free Models on your WordPress website: 24/7 Customer Support Provide instant answers to visitors at any time, improving engagement and reducing support workload. Lead Generation Assistant Qualify visitors and collect contact information through conversational interaction.

It provides instant, automated support 24/7 and captures visitor details with an optional pre-chat form. Free AI Integration Use free models from OpenRouter without additional costs or complex setup. Configuration – Setting up your AI Chatbot Get a Free API Key from OpenRouter.ai (Yes, it’s free!). OpenRouter offers access to over 400 models, including ChatGPT, Claude, DeepSeek, Gemini, and many others, all at competitive prices! Enter your OpenRouter API Key in the “Settings” tab. Choose an AI Model. Free models have the suffix “:free” at the end of their name. Note that all models are accessed THROUGH OpenRouter, regardless of the original provider. Provide context about your website in the “Information for responses” field. Customize the chatbot’s appearance in the “Style” and “Images” tabs. Click “Save settings”. Remember to refresh your website (Ctrl+F5 or Cmd+Shift+R) after saving, otherwise the changes may not be displayed correctly due to caching. Message and IP Saving You can enable or disable the saving of chat messages and user IP addresses in the “Messages” tab of the settings page. Message saving is disabled by default for privacy reasons. If enabled, all chat messages and IP addresses will be stored securely within the plugin’s dedicated database. Using a dedicated database offers several advantages: Simplified Management: All chatbot-related data is contained in a single location, making it easier to manage and maintain. Reduced Impact: Storing data separately minimizes the impact on your website’s core database performance. Important: If you choose to enable message and IP saving, you MUST update your website’s privacy policy to reflect this data collection practice and inform your users accordingly. You are responsible for complying with all applicable privacy laws. Enabling “Powered by NewCodeByte” Enabling “Powered by NewCodeByte” helps me support the development of this free plugin.
