Replace WordPress default comment area for posts with an AI chat powered by either DeepSeek or OpenAI.

== Description ==
Comment2AIChat disables WordPress default comments on posts and replaces them with a chatbot-like interface.  
It provides integration with two models:
1. **DeepSeek** (model: `deepseek-chat`)
2. **OpenAI** (model: `o3-mini`)

A settings page under "Settings > AIChat" allows you to select the model, enter your API key, and set a custom prompt.  
Use the shortcode `[comment2aichat_chat]` to display the chat interface anywhere (e.g., on pages or within posts).  
By default, the AI chat is automatically appended to single post contents.

== External Services ==
This plugin connects to external APIs to provide AI chat functionality.  
- **OpenAI API**  
  When the "OpenAI" model is selected, the plugin sends the user's message and a system prompt to OpenAI's endpoint at `https://api.openai.com/v1/chat/completions`.  
  The API key is used for authentication.  
  Please review OpenAI’s [Terms of Service](https://platform.openai.com/terms) and [Privacy Policy](https://platform.openai.com/privacy) for details.

- **DeepSeek API**  
  When the "DeepSeek" model is selected, the plugin sends the same data to DeepSeek's endpoint at `https://api.deepseek.com/chat/completions`.  
  The API key is used for authentication.  
  Refer to DeepSeek's official documentation for its terms of [DeepSeek Privacy Policy](https://cdn.deepseek.com/policies/en-US/deepseek-privacy-policy.html).

== Installation ==
1. Upload the entire `comment2aichat` folder to the `/wp-content/plugins/` directory.
2. Activate the plugin through the 'Plugins' menu in WordPress.
3. Go to `Settings > AIChat` to select a model (DeepSeek or OpenAI), enter your API key, and optionally modify the assistant prompt.
4. Use the shortcode `[comment2aichat_chat]` to display the chat interface, or simply view any single post to see the chat appended below the content.
