Try Leap free
Leap's AI detection runs entirely in your browser, free, with no account and nothing sent anywhere. It scores text from 0 to 100 based on writing signals like sentence-length variation, stock AI phrases, hedging words, em-dash density, and repetition, and highlights the sentences that weigh most. The humanizer does a cleanup pass: it replaces stock AI phrases, removes em dashes and invisible characters, adds contractions, and marks sentences of uniform length so you can vary them. Neither tool guarantees any outcome with third-party detectors, and a score is a signal, not proof.
