Does Unicheck detect AI?
Unicheck was built to find copied and paraphrased text. Turnitin bought it in 2020 and is discontinuing it, moving schools to Turnitin's own products, which do check for AI. Here is what that means if your course used Unicheck.UpdatedWhat happened to Unicheck
Unicheck was a plagiarism checker that plugged into Moodle, Canvas and other learning platforms. Turnitin bought it in 2020 and has since told schools it is discontinuing Unicheck and moving them to Turnitin's products.Where AI checks come from now
At a school that moved to Turnitin, AI scores come from Turnitin's AI writing detection, if the school licenses it. Other schools added a different detector, such as Copyleaks, to their learning platform. If you're not sure what your course uses, look at the name on the report or ask your instructor. See does Turnitin detect AI?, does Moodle detect AI? and does Canvas detect AI?.If your writing gets flagged
Open the full report from the assignment, whichever tool produced it. It shows the AI score or the similarity matches, with the passages highlighted. Screenshot it before you do anything else.- Keep your drafts, notes, and outlines so you can show how the text was written.
- Ask your instructor which parts of the report triggered the flag and request a conversation before any formal process.
- Remember that an AI score is a signal, not proof. No detector score alone should be the only basis for an accusation.
Pre-submission checks
Run the draft through a free detector to catch obvious AI habits, revise, and check again. Leap's free AI detector runs in your browser with no signup and shows the sentences that read most like AI. No outside tool can predict your school's detector exactly, so treat any score as a hint, not a guarantee.The responsible-use note
Defeating AI detection does not change the underlying integrity question. If AI help is prohibited on a specific assignment, editing text to pass detection is still a policy violation, just harder to catch. This page exists to help writers understand the tooling, not to encourage misconduct. Know your institution's rules, and disclose AI use where required.If AI assistance is permitted and you just want to verify your final text reads naturally, run it through Leap's free AI detector first. If scores look high, the humanizer can do 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 yourself. It does not guarantee passing any detector.Frequently asked questions
