Frequently asked questions

Is this an AI detector?
No. We only show simple statistics (length, diversity, long sentences) to help you edit drafts. We do not label text as AI- or human-written.
Can I use this for grading or plagiarism decisions?
No. Automated surface metrics are not evidence of authorship or originality—use your institution’s policies and primary sources.
Is my lesson text uploaded?
No. Everything runs in your browser.
