Reasons
Review rhythm, repetition, and generic phrasing.
Next step
Ask for notes, sources, or revision history.
Questions
Can students be falsely flagged?+
Yes. Any detector can be wrong, especially for polished, translated, templated, or heavily edited writing.
Can this prove AI authorship?+
No. AI Checker Lab returns probability estimates to help you review content. It should not be used as proof or an accusation.
Does AI Checker Lab save my checks?+
Anonymous checks are not saved to an account. Signed-in users can save recent check history with a short preview, scores, and result details so they can review past results.
Why can AI checkers disagree?+
AI detection is uncertain. Different tools weigh style, length, topic, and evidence differently, so context matters.
