Frequently Asked Questions

Does the plugin work with all versions of Microsoft Word?

The plugin works with Microsoft Word 2016 and later on Windows and Mac, as well as Word for the web (Office 365). It integrates via the Microsoft Office Add-ins platform for maximum compatibility.

Is the Word plugin free to use?

Yes, the plugin works with the Free plan — 3 credits at signup plus 1 free credit every day. For unlimited daily credits and scans of up to 25,000 words, you can upgrade to Pro at $9.99/month.

Can I scan an entire document at once?

Absolutely. Click the "Scan Document" button in the ribbon toolbar to analyze your entire document. The plugin processes the full text and highlights AI-generated sections inline with color-coded confidence scores.

Does the plugin store or share my documents?

Your document text is sent securely to produce the result and is not used to train our models. See our privacy policy for retention details.

Can I generate reports for academic integrity purposes?

Yes. Every scan produces a shareable report with the overall AI probability and the sentence-level breakdown, which you can keep with your records or share with a colleague. No detector report should be the sole basis for an academic-integrity decision.

How does this compare to Turnitin's AI detection?

In our April 2026 benchmark (500 texts) our engine scored 95.2% accuracy with 3.1% false positives, and Turnitin AI scored 83.8% with 12.1% false positives; it is our own benchmark, so weigh it accordingly. Unlike Turnitin, which requires institutional licensing, our plugin is available to individual educators on a Free plan or Pro at $9.99/month. See our detailed comparison at /turnitin-alternative.
