PDF Annotator | Mark Up PDFs | Digital Worksheets | Smartboard Tool | Teacher Tool


An online digital resource that lets teachers draw right on top of PDFs in real time. Perfect for marking up worksheets, annotating slides, highlighting key passages, working through problems live, and giving feedback on handouts. Great for classroom instruction, whole-group lessons, homeschool learning, and interactive teaching on a projector or smartboard.


What the Write On! App Does:

  • Upload any PDF from your device and draw directly on the page
  • Choose a pen or a see-through highlighter, with 10 colors and an adjustable size
  • Works with a mouse, finger, or stylus, and two-finger scrolling on touchscreens lets you move through the document without leaving stray marks
  • Undo your last stroke or clear a page in one click
  • Save a marked-up copy as a new PDF (your original file is never changed)
  • Works entirely online in your browser—no installation, logins, or ads
  • Clean, easy-to-read interface designed for live classroom use
