Frequently Asked Questions
By calculating sentence-level n-grams (combining 3-word overlap hashes), this tool processes your input text and matches it against uploaded files client-side without sending information outside.
Currently, the checker compares plaintext (.txt) references directly. If you have DOCX documents, simply copy and paste the text into the checker or reference blocks.
