FAQ

AI vocabulary questions

Why do these words signal AI?
Large language models are trained to favour certain "safe", formal connectors and flourishes — words like "moreover", "delve", "tapestry" and phrases like "it is important to note". They appear far more often in AI text than in natural human writing, so detectors and editors treat heavy use as a signal.
Does removing these words beat AI detectors?
It helps, but vocabulary is only one signal. Detectors also weigh sentence rhythm, predictability and structure. Use this tool to clean obvious tells, then check the result with a full AI detector.
What does the risk score mean?
It reflects the density of flagged terms relative to your total words. Under ~20 is clean; 20–50 is worth a pass; above 50 means the vocabulary reads strongly AI-generated.
Will it flag words I legitimately need?
Sometimes — context matters. The tool surfaces candidates; you decide which to keep. A few flagged words in a long piece is normal.
Is it free and private?
Yes — free forever, no signup, and your text never leaves your browser.
Does it work on mobile?
Yes, the layout stacks cleanly on phones.
