livbedi2006/Plagiarism-Detector — reverse-engineered prompt

Build me a simple plagiarism detector web app in Python where a user can paste an original text and another text they want to check, then click a button to see if the second one looks copied.

I want it to clean the text, compare the two pieces using NLP, and show a clear similarity percentage. Use TF IDF, cosine similarity, Jaccard word overlap, and a basic machine learning model like Logistic Regression if needed. The result should say whether it seems original or plagiarized, with easy color feedback like green for low risk, yellow for medium risk, and red for high risk.

Make the interface friendly in Streamlit, with two large text boxes, a check button, a progress or score display, and a small breakdown of the different similarity scores. It should work best for English text and feel polished enough for a student project demo. Include any needed setup files and make sure it can run locally with one command.
