What Leap's detection actually tells you
Leap scores text from 0 to 100 based on writing signals: uneven versus uniform sentence length, stock AI phrases, hedging and transition words, em-dash density, and repetition. It highlights the sentences that weigh most on the score.That score is a signal, not proof. Any detector can be wrong, and no score should be the only basis for accusing anyone of using AI. This applies to Leap and to Walter Writes alike.What Leap's humanizer does
- Replaces stock AI phrases with plainer wording
- Removes em dashes and invisible characters
- Adds contractions where they fit
- Marks sentences of uniform length so you can vary them yourself
When Walter Writes is the better pick
- You specifically want student-focused positioning. Walter's marketing, docs, and examples are aimed at academic users, so the onboarding may feel more relevant if that matches your context.
- You prefer a minimal detection UI. Walter's single-score detector is simpler than a multi-signal breakdown.
- You are already onboarded. If Walter works for you, switching tools has real friction, so don't change just for marginal differences.
