# `ai-detect`

CLI tool to detect if a text is written by AI using the Tencent Matrix AI Detection tool.

## Usage

```bash
# Detect from a file
ai-detect path/to/article.txt

# Detect from a text string (in quotes)
ai-detect "Some short text to test..."
```

## Options

*   `<input>`: File path or text string to analyze.

## Examples

```bash
# Check a local file
ai-detect ./blog-post.md

# Check specific text
ai-detect "Here is some text generated by ChatGPT to test the detector."
```

## Notes

*   Uses `puppeteer` to automate `https://matrix.tencent.com/ai-detect/`.
*   **Rate Limits:** The website limits free usage (e.g., 5 times/day). If you hit the limit, the tool will exit with an error.
*   **Privacy:** Text is sent to a third-party service (Tencent).
