Annotate with Apple Pencil
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
iPad
Voice pen: draw on the screenshot while you talk, and Comark transcribes and numbers every note. US$6.99/month after a 14-day free trial, or US$69.99 once.
Comark turns your iPad into a dedicated markup surface for your Mac or Windows computer.
Capture any screen on your computer, annotate it with Apple Pencil, then send it straight back to the desktop clipboard. Everything runs over your own Wi-Fi network. No account, no cloud, no sign-in.
HOW IT WORKS
1. Download the free Comark companion app for Mac or Windows from comark.work
2. Pair your iPad with a 6-digit code shown on the computer
3. Tap Capture, annotate, and copy the result back to your computer
CAPTURE
- One tap capture of any connected Mac or Windows display
- Pick which monitor to capture when several are connected
- Import images from your photo library
- Automatic reconnect when the network drops or the device locks
ANNOTATE
- Pen and highlighter with adjustable color, width, and opacity
- Rectangle, circle, and arrow shapes
- Text annotation with keyboard or voice input
- Crop to a rectangle or to a freehand region, with full undo
- Two-finger pinch, zoom, and pan that never interfere with drawing
- Eraser and unlimited undo or redo
VOICE MARKUP
- Voice pen: start drawing and Comark records, transcribes, and drops a numbered marker on the image
- Every marker gets a matching entry in the bottom caption area
- Automatic gain control lifts quiet speech into a recognizable range
- Apple on-device speech recognition is the default, with recognition language selectable
- Optional third-party providers: Alibaba DashScope, Volcengine, and any compatible transcription endpoint using your own API key
BOTTOM CAPTION
- One text caption per canvas, typed or dictated
- Renders live under the image and exports together with the annotation
- Font size and height adapt to the amount of text
SEND BACK
- Copy a single annotation or a multi-selection to the desktop clipboard
- Local clipboard copy for use inside iPadOS
- Paste into Codex, chat apps, docs, notes, or a browser
PRIVACY
- No account and no user tracking
- Images and audio stay on your devices and your local network
- Third-party speech services are only contacted when you configure your own key
