I have tested your tool, first thing i notice Plagiarism is not perfect work as duplichecker, , need to more work on it,
1. i notice there should be a button that one click make unique all while Plagiarism.
2. Ai detectors make perfect as auto highlight ai line , so user easly understand where show ai.
3. humanizer not show accurate result yet. make it more accurate
4. need to improve ui - as user click on text while Plagiarism time , user curser not show as user friendly, sometime user real-time want to make change , so improve this .

now i noticce very good things in this tool -
1. first thing this is all in one tool - AI detectors, Plagiarism checker and research based , so i like this tool ,
2. this tool is innovative and most demanding tool as today trend .
3. if all changes made made by developer then this one tool user never need to switch to another tool.
