# Regex Highlighter

Regex Highlighter is a powerful Chrome extension designed to instantly find and highlight text on any webpage using regular expressions. With the integrated power of AI, you can also generate complex regular expressions from natural language descriptions.

## Key Features

- **Real-time Regex Search**: Instantly searches and highlights all matches for your regular expression on the current web page.
- **AI-Powered Regex Generation**: Describe the text pattern you're looking for in plain English, and let AI generate the correct regular expression for you.
- **Persistent History**: Automatically saves your AI-generated queries. Quickly access, copy, and reuse your past expressions.
- **Input Field Highlighting**: In addition to standard text, the extension can also highlight matches within `<textarea>` and `<input>` fields.
- **Secure & Private**: Your API key and search history are stored securely on your local device using `chrome.storage.local` and are never shared.

## How to Use

### 1. Searching with a Regular Expression

1. Click the extension icon in the Chrome toolbar.
2. Enter your regular expression into the main input field.
3. Click the **Search** button.
4. All matching text on the current page will be highlighted.
5. To remove the highlights, clear the input field and click **Search** again.

### 2. Generating a Regex with AI

1. Click the settings icon (⚙️) to enter your DeepSeek API key. (This is a one-time setup).
2. Click the **AI** button.
3. In the prompt window, describe the text pattern you want to match (e.g., "find all email addresses").
4. Press **Enter**. The AI will create a regular expression and place it in the main input field.
5. Click **Search** to highlight the results on the page.

### 3. Using the History

1. Click the **History** button to view a list of your previously generated expressions.
2. Hover over an item to see the full query and expression if the text is too long.
3. Click the **Copy** button next to an item to instantly copy the regex to the main input field.
4. Click the **Delete** button to remove an item from your history.
