Bulk upload

Upload a class set in one batch

Drop in a whole submission set instead of checking 30 papers one at a time. Each paper gets its own report, filed in the folder for that class.

  • An individual report for every paper
  • Folders by course, class or semester
  • Every report saved and easy to find later
Folders in Plagiarism Checker Plus: All reports, History essays and Research papers
Sentence-level evidence

See exactly which sentences match

A percentage is a prompt, not a verdict. The report shows every matched sentence and where it came from, so you can judge each one yourself.

  • Each match underlined in its source’s colour
  • Open the source text beside the student’s
  • AI-likely sentences flagged in the same report

Remarks for feedback

Leave remarks on any sentence

Note what you found before you meet the student. You arrive with specific sentences and sources, and the report carries your notes if the case goes further.

  • Select text to add a remark
  • Reply and resolve, like comments in a doc
  • Share a secure link or download a PDF
