Usually less concerning, but still verify if the context matters. A clean score does not prove human authorship.

ZeroGPT alternative: free and paid AI detector options.

Score reading
Do not read a detector score as a verdict.
Use the score to decide what to inspect. Short text, formulaic writing, non-native English, heavy editing and translated drafts can all move the result.
30-70%
Read highlighted passages. Look for repeated sentence shapes, vague claims, generic intros and a rhythm that feels too uniform.
70-100%
Review seriously, but do not punish automatically. Ask for drafts, notes, revision history and context before drawing conclusions.
