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

AI Chatbot Free Models empowers you to integrate a cutting-edge AI chatbot into your WordPress website! It is a multi-provider solution: connect directly to OpenAI (ChatGPT), Anthropic (Claude), Google (Gemini), DeepSeek, Groq, xAI (Grok), Together AI, Mistral, Perplexity, or OpenRouter (over 500 models with a single API key), and you can even point it to any custom OpenAI-compatible API endpoint. 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 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.).

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 or other supported providers without additional costs or complex setup. Configuration – Setting up your AI Chatbot Get an API Key from one of the supported providers (OpenAI, OpenRouter, Anthropic, Google, DeepSeek, Groq, xAI, Together AI, Mistral, or Perplexity) from its official website. Enter your API Key in the “Settings” tab and select the matching provider. Choose an AI Model. On OpenRouter, free models have the suffix “:free” at the end of their name. Other providers list their free or low-cost models directly. 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. Window Size on Mobile The “Style” tab contains two independent height settings: Chat Window Height — the height of the chat window in pixels on desktop browsers. Chat Window Height (mobile) — the height used on phones and small tablets (up to 768px wide), where the desktop height would not fit the screen. Leave the mobile value at 0 to keep the automatic size, which is 70% of the visible height. Values larger than the space available on the screen are automatically reduced, so a large number can never push the window off the screen. Using the Plugin Behind a CDN or a Proxy The plugin limits how often a visitor can send messages, and it identifies each visitor by IP address. If your site sits behind a CDN (Cloudflare) or a reverse proxy, the address seen by the server is the one of the proxy, not the one of the visitor. To make the rate limiting work correctly in that setup, declare the proxies you trust in wp-config.php: Values can be single IP addresses or CIDR ranges. The forwarded headers are read only when the constant is present and the address that received the request matches one of them, which prevents visitors from forging their IP through a request header. Without the constant the plugin keeps using the direct connection address and nothing changes. 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.

Developer Hooks & Filters MxChat has filter hooks for developers who want to extend it without editing plugin files, including mxchat_should_index_post (return false to leave a post out of the knowledge base; it also receives import, auto_sync or reimport as the context), mxchat_before_process_post (change a post before it is indexed, or return false to skip it), mxchat_system_instructions (adjust the system prompt for each reply), mxchat_gemini_safety_settings (Gemini safety thresholds), mxchat_reference_shortcodes (shortcodes whose referenced content is imported), mxchat_index_use_rendered_page (return true or false to decide whether a post’s published page is read for its text), mxchat_filter_roles_rate_limit (reorder a logged-in user’s roles to choose which role’s rate limit applies; the first role in the list is used), mxchat_lead_retention_days (how many days a lead is kept after the visitor’s last chat; 0 keeps leads) and mxchat_stream_request (add headers to, or change the address or body of, a streamed chat request; WordPress’s own HTTP filters do not reach streamed replies). Add-ons can also call mxchat_generate_media_image() to create an image with the site’s image model and save it to the Media Library. Every hook is documented with code examples at mxchat.ai. External services To answer chats and generate content, MxChat sends requests with your own API key to the AI provider you choose: the visitor’s message, the recent conversation and the matching knowledge-base text.
