Frequently Asked Questions

How accurate is it?

No AI detection tool is perfectly accurate. Results are probability estimates based on statistical patterns. Treat them as one signal among others, not as definitive proof.

Why do I need at least 30 words?

Short snippets do not give the model enough signal to produce a reliable score. We require 30 words minimum so the result is meaningful.

What file types are supported?

You can paste text directly or upload PDF, Word (.doc/.docx), Excel (.xls/.xlsx), or TXT files up to 20 MB.

Is my text uploaded?

Yes, for this tool only. Text is sent to a hosted AI model so it can produce a score. It is processed in memory and not stored after the response is returned.
