If you currently use Turnitin, Validiti Witness delivers the same plagiarism check — on your hardware, with signed citations.

For individual teachers, small schools, independent journals, and writing instructors, Validiti Witness checks any passage against any record corpus you own. Match the assigned readings, prior student work, your own archive — without sending the student's work to a third-party cloud.

Validiti Verus

$199 / yr per seat

Records-query with signed citations. Plagiarism check is one of the things it does well.

Paste a passage — get back every matching source row with frequency + timestamp
Build your own corpus: assigned readings, prior student submissions, journal back-issues
Student work never leaves your hardware — FERPA-clean by construction
Every match has a signed citation to the source row, defensible if challenged
"No match found" is structurally honest — not "appears original," just "not in the record"
