# Firefox Extension

The [Firefox Extension](https://addons.mozilla.org/en-CA/firefox/addon/ai-detector-originality-ai/) delivers highly accurate AI detection and plagiarism checks directly within Google Docs and Firefox, making it a seamless part of your core workflow for writing and reviewing content.

Designed for writers, students, educators, editors, and publishers, the extension helps you maintain transparency, prove authorship, and reduce false positives with advanced Writer Replay and auto-typing detection.

**Note:** No AI detector is 100% accurate. AI scores should always be reviewed using human judgment.

## What You Can Do with the Firefox Extension

* Scan Google Docs for AI-generated text and plagiarism
* Scan any web page or selected text in Firefox
* Watch a character-by-character replay of how a document was written
* Detect non-human typing behaviour, including auto-typing tools
* Generate shareable, read-only reports
* View AI scores, plagiarism scores, word counts, paste activity, contributors, and revisions

## How It Works

1. Install the Originality.ai [Firefox Extension](https://addons.mozilla.org/en-CA/firefox/addon/ai-detector-originality-ai/).
2. Click the Originality.ai icon and log in.
3. Open a Google Doc.
4. Click **Scan** to analyze the document for AI-generated writing and plagiarism.
