Educators · Editors · Recipients

  1. Have the ExtraProof PDF or JSON record ready, along with the original file if needed.

I work with Moodle.

Schools · universities · teachers

  1. Students open the ExtraProof activity in their course and connect it to their Word session.
  2. After the session ends, ExtraProof shows the recipient, course and activity. Confirming submission sends the document and signed record together.
  3. Teachers see the submission and verification result. Moodle receives a separate “Record checked” status column.
