Quick answers to what people ask us about AI detection.
Less than most people assume. Every AI detector is probabilistic, and research has repeatedly found false positives on genuine human writing, with higher rates for non-native English writers. Treat a score as a prompt to review, never as proof.
Most measure how predictable your word choices are and how much your sentence length varies. Human writing tends to be uneven. AI output tends to be smooth and consistent, and that flatness is what registers.
Lunchbreak runs your text past the detectors institutions and publishers actually use, including Turnitin, GPTZero, Copyleaks, Originality and Sapling, then shows you each result rather than a single averaged number.
Because they are built differently. One judges sentence by sentence, another by paragraph, another on token probability. Seeing several at once tells you far more than trusting any single one.
