The Self-Plagiarism Checker is a great tool for you if you are seeking to compare your work to only the sources you actually used, such as your own previous assignments or those of fellow students.
The checker is compatible with the following file formats:
.doc
.docx
.pdf
.txt
If you have a document in a different file format, we recommend converting it to .docx or .pdf and then uploading it as a source.
