More information
How can I tell if a human wrote something?
Look for personal details
People mention real names, places and small mistakes.
Watch for the same shape
AI text often has neat lists and sentences of the same length.
Check the claims
AI can state made up facts with total confidence.
How long should the text be?
At least 100 words. Longer text gives a more reliable answer. The limit is about 650 words.
Can the checker be wrong?
