About ZeroGPT's AI Detection
ZeroGPT often flags legitimate human writing as AI-generated, making it one of the more aggressive detectors on the market.
GPTypo helps you identify which sentences trigger false positives and fix them with targeted suggestions — protecting your authentic work.
What ZeroGPT looks for
These are the types of signals that ZeroGPT's classifier measures. GPTypo checks for the same patterns.
Sentence uniformity
AI text tends to produce sentences of similar length and rhythm. High variance is a signal of human writing.
Low perplexity
Predictable word choices with few surprises. Human writers are messier and less statistically smooth.
AI vocabulary
Overuse of phrases like "furthermore," "it is important to note," and "multifaceted" that appear far more often in AI output.
Structural repetition
Repeated paragraph openers, parallel sentence structures, and formulaic transitions between ideas.
Missing texture
Human writing has contractions, hedging, asides, and first-person markers. AI text tends to be uniformly polished.
Document coherence
AI text often has a narrow vocabulary range and smooth sentence-to-sentence flow that reads as artificially consistent.
