+# Local ChatGPT UI
+
+This is a simple, local-only interface for interacting with the OpenAI API. It's a single HTML file that you can run directly in your web browser.
+
+The main goal is to provide a straightforward chat experience without needing to install anything or run a web server. All your data, including your API key and chat history, is stored on your own computer in the browser's local storage.
+
+## How to Use
+
+It's designed to be as easy as possible to get started:
+
+1.  Download the project files (click `Code` > `Download ZIP`).
+2.  Unzip the folder.
+3.  Double-click the `index.html` file to open it in your browser.
+
+That's it. Once it's open, you just need to enter your OpenAI API key, and it will load the available models.
+
+## Functionality
+
+Here is what the tool can do:
+
+*   **Chat with the OpenAI API:** The main function is to send and receive messages.
+*   **Save Chat Sessions:** Your conversations are automatically saved and grouped into different sessions that you can switch between.
+*   **Edit Session Names:** You can rename your chat sessions.
+*   **Import/Export:** You can export all your chats to a single JSON file or import them back in.
+*   **File/Image Uploads:** Allows you to attach files and images to your prompts (for models that support it, like GPT-4o).
+*   **Streaming Responses:** Shows the AI's response as it's being generated.
+*   **Model Selection:** Lets you pick from the models available with your API key.
+
+## Beta Features Disclaimer
+
+Some of the more complex rendering features were added for convenience but are still in a **beta stage**. They are a terrible built and may have bugs or fail to render correctly in some cases.
+
+*   **Markdown Detection:** Basic Markdown like headers and bold text should work, but it can be unreliable with more complex formatting.
+*   **Code Block Detection:** It tries to find and highlight code blocks, but this might not always work as expected, especially with nested or oddly formatted code.
+*   **LaTeX Rendering:** Support for math equations is experimental and may not render all expressions correctly.
+
+These features are included as-is. Improvements may be made in the future.
+
+## Contributing
+
+If you want to fix something or add a feature, feel free to do so. Since there is no build process, you can edit the `.js` and `.css` files directly and just refresh the page in your browser to see the changes.
+
+It should be responsive to a acceptable level
