How Leap's detector works
Leap's detector runs entirely in your browser. It scores text from 0 to 100 based on writing signals: uneven versus uniform sentence length (burstiness), stock AI phrases, hedging and transition words, em-dash density, and repetition. It highlights the sentences that weigh most on the score.The score is a signal, not proof. Any detector can be wrong, and a score should never be the only basis for accusing anyone of using AI.When Winston AI is the better pick
- You need professional PDF reports you can hand to a stakeholder. Teachers, editors, and HR teams use Winston's PDF output because it is formatted for sharing with students, clients, or legal contexts. Leap has no equivalent report feature.
- You need plagiarism checking bundled with AI detection. Winston combines both in one scan with one report. Leap has no plagiarism checker, so if that is part of your workflow, Winston is the right pick.
- You scan many documents at once, such as teacher grading or agency QA. Winston's batch processing is built for that. Leap checks one text at a time.
- Your organization already pays for detection tools and needs team seats and admin controls.
When Leap is the better pick
- You want to check your own writing for free, with no account and no word limit tied to a plan.
- You care about privacy: Leap runs in your browser and your text is never sent to a server.
- You want to clean up AI writing signals yourself. Leap's humanizer replaces stock AI phrases, removes em dashes and invisible characters, adds contractions, and marks sentences of uniform length so you can vary them.
- You are an individual writer, student, or creator rather than an institution reviewing other people's work.
