PDF annotation

Teach from the PDFs you already have

Upload a worksheet or slide deck and mark it up live — pen, calligraphy ink, highlighter, shapes, text and sticky notes — with smooth continuous scroll and pinch-to-zoom.

The problem

Your best resources are already made — worksheets, past papers, slide decks. But a PDF is static: you can't write on it in front of the class, highlight the key step, or come back to it next year with your notes intact.

ClassKite makes your PDFs teachable

Bring a PDF (or PowerPoint) into ClassKite and annotate it live on any device. Draw, highlight, add text and sticky notes, scroll through every page, and zoom in on the detail that matters. Your annotations autosave as you go and are kept safely so you can reuse the lesson later.

How it works

  1. 1

    Upload your file

    Add a PDF or PowerPoint — ClassKite turns it into pages you can teach from.

  2. 2

    Annotate live

    Use the pen, calligraphy, highlighter, shapes, text and sticky notes to explain as you go.

  3. 3

    Scroll & zoom

    Move through every page with continuous scroll, and pinch or wheel-zoom to focus on the detail.

  4. 4

    It saves itself

    Annotations autosave and sync — and keep working even if the connection drops.

What you get

A full ink toolbox

Pen, calligraphy ink, highlighter, eraser, shapes (rectangle, ellipse, arrow), text boxes and sticky notes.

Natural, readable ink

Calligraphy strokes respond to your stylus for a handwritten feel; the highlighter blends like the real thing.

Continuous scroll

Read and annotate multi-page PDFs in one smooth, scrollable view.

Crisp pinch-zoom

Zoom in to model a step, then back out — the page re-renders sharp every time.

Autosave + offline-safe

Edits save automatically and survive a reload or a dropped connection, then re-sync.

Built for touch & stylus

Palm rejection and stylus-friendly controls make it comfortable on a tablet or smart board.
