Cladis

Plagiarism detection that reads structure, not keywords.

Upload a folder of student submissions — code or essays. Cladis scores every pair by structural similarity and returns a ranked list, highest first, with side-by-side evidence for every match. Renamed variables, reshuffled functions, and reworded passages don't hide the original.

Training-free and parameter-free — no ML, no setup, no software to install. Every plan starts with a 14-day free trial.
