AI Detector: Frequently Asked Questions
Is an AI detector accurate?
No detector is fully reliable. Human text can be flagged and AI text can pass. Use the result as a guide only.
How much text should I paste?
At least 100β200 words gives a more useful estimate.
Can teachers rely on this?
Never accuse anyone based only on a detector score. Talk about the work and look at drafts instead.
How do I make my writing more human?
Add personal experience, specific examples, opinions and varied sentence length.
Is my text stored?
No. It is analysed and not saved on our site.
