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.
What Leap's humanizer does and does not do
Leap's humanizer is a cleanup pass that runs in your browser. It replaces stock AI phrases, removes em dashes and invisible characters, adds contractions, and flags sentences of uniform length so you can vary them yourself.It does not guarantee passing any detector, and it does not promise to bypass Turnitin, Winston, or any other checker. The goal is to help you revise text so it reads more naturally, not to evade detection.Try Leap against your own text

Frequently asked questions
No. Winston is a detection and reporting product, not a humanizer. Its strongest differentiator is professional PDF report output, formatted for teachers, editors, and HR teams. If you need to revise AI-assisted text, you need a separate tool for that job. Leap's humanizer is a free cleanup pass that runs in your browser.
We do not claim one is more accurate than the other, and no detector's marketing accuracy claims should be taken at face value. Every AI detector can produce false positives and false negatives, and every detector's signal drops on heavily revised text. Treat any score, from Winston, Leap, or anyone else, as a signal rather than proof.
Winston AI is a paid subscription product with a limited free trial, priced for professional reporting workflows with word allowances and team tiers. Leap's detector and humanizer are free with no account and no word limit tied to a plan. They are priced for different jobs: institutional review versus individual writing.
Yes. Plagiarism cross-reference is bundled into the same scan as AI detection, and both appear in the downloadable PDF report. That is a real strength if you need both capabilities in one shareable document. Leap does not include a plagiarism checker.
Educators without institutional Turnitin access, freelance editors, agency operators, and content leads who need professional detection reports to hand to a stakeholder. Winston's PDF output, batch processing, and bundled plagiarism serve that reviewer-side workflow. Leap is built for individual writers checking and revising their own text, not for reviewing other people's work.
Yes. The products solve different sides of the same content loop. A publisher might use Winston to scan inbound submissions and deliver editor reports, and Leap to clean up outbound AI-assisted drafts before they ship. Neither is a substitute for the other.
