What is Lunchbreak AI?
Lunchbreak AI is an AI trace detection and rewriting tool. Its official positioning is "Check Your Writing for AI Flags", allowing students to check their work against detectors such as Turnitin, GPTZero, and Copyleaks before submission. Its workflow involves pasting the text, viewing the judgments of each detector, and then deciding whether to rewrite the wording. The official emphasizes that the detection itself is free and does not require a credit card. The page also displays the judgment comparison of the same text before and after processing.
