About Sapling's AI Detection
Sapling's AI detector analyzes writing rhythm and vocabulary patterns to identify machine-generated text.
GPTypo highlights which sentences trigger detection, giving you specific guidance on what to change.
What Sapling looks for
These are the types of signals that Sapling'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.
