About

# Chat Index Navigator 📑

A Chrome extension that adds a **floating, navigational sidebar** to ChatGPT. It automatically indexes your conversation in real-time, allowing you to jump between prompts and answers instantly.

## ✨ Features

* **Real-time Indexing:** Automatically scans the chat and builds a Table of Contents.
* **Smart Previews:** Shows the first few words of your prompt and the start/end of the AI's response.
* **Visual Tags:** Automatically detects and tags `[code]`, `[image]`, and `[table]` content.
* **Scroll Sync:** The sidebar highlights the current section you are reading in the main chat window.
* **Draggable & Resizable:** Move the sidebar anywhere on the screen and resize it to your liking.
* **Customizable Settings:**
    * Toggle "Show Answers" on/off.
    * Adjust word count preview (10, 20, or 40 words).
    * Settings persist across reloads.
* **SPA Support:** Works seamlessly when switching between different chat conversations without reloading.

## 🚀 Installation (Developer Mode)

Since this is a custom local extension, you install it via "Load Unpacked":

1.  Download or clone this repository to a folder on your computer.
2.  Open Chrome and navigate to `chrome://extensions/`.
3.  Toggle **Developer mode** in the top right corner.
4.  Click **Load unpacked** (top left).
5.  Select the folder containing `manifest.json`.
6.  Open ChatGPT, and the sidebar will appear automatically!

## ⚙️ Usage

* **Navigate:** Click any item in the sidebar to smooth-scroll to that message.
* **Settings:** Click the **Gear Icon (⚙️)** in the sidebar header to open the settings panel.
* **Move:** Click and drag the header (where it says "Index") to move the sidebar.
* **Resize:** Drag the bottom-right corner (or any edge) to resize the panel.
* **Collapse:** Click the `—` button to minimize the sidebar into a floating bubble.

## 🛠️ Troubleshooting
