Mark your place.
On any screen. Over any app.
Ace Overlay is a click-through overlay for Windows that lets you pin arrows, notes, highlights and screenshots on top of everything — CAD, trading charts, spreadsheets, anything. Your markers stay put while you work underneath them.
Windows 10/11 · free version, no account needed
Three keys. That's the whole workflow.
Press the hotkey
Ctrl+Alt+E flips the overlay into edit mode — a toolbar appears over whatever you're doing.
Draw your markers
Arrows, boxes, notes, highlights, numbered pins — snap them exactly where you need to look next.
Keep working
Press it again and the overlay goes click-through. Your markers float above every window, out of the way.
Built for keeping your spot
Click-through by default
The overlay never steals your mouse. One hotkey flips into edit mode when you want to draw.
13 marker tools
Arrows, lines, shapes, freehand, highlights, crosshairs, numbered markers, sticky notes, text, screenshots and images.
Multi-monitor Pro
One continuous canvas across every display. Drag objects between monitors.
Layers Pro
Organize markers into layers you can hide, lock, reorder and fade independently.
Radial tool wheel Pro
Hold a key and a tool wheel opens around your cursor — favorites and recents included.
Clipboard history Pro
Ctrl+Alt+V opens the last 10 text and image copies at your cursor — with a 1 MB cap so huge pastes stay out.
Snapping Pro
Grid, screen-edge and object snapping with adjustable strength for precise placement.
Auto-save
Your overlay is saved continuously and restored on launch. Export and import workspaces as files.
Node-locked licensing
One license, one device — move it yourself any time, add seats when you need them.
Pro New in 1.2
Never lose a copy again
Hit Ctrl+Alt+V and the last ten things you copied — text or images — open in a table right at your cursor. Pick one and it’s back on the clipboard, ready to paste into any app. Oversized items over 1 MB are skipped so the history stays light.
- Last 10 text & image copies
- Opens at the cursor, anywhere
- 1 MB per-item cap · oldest drops off
Where it earns its keep
Works with anything
No plugins, no integrations, no setup. The overlay floats above whatever you already use — desktop apps, browsers, remote sessions — and takes seconds to learn.
Precision work
Reference marks, callouts and reminders pinned exactly where you need them — over drawings, charts, dashboards or data — so nothing gets lost mid-task.
Staying on track
Mark the cell you were reconciling, the line you were reviewing, the field you always miss — switch tasks and pick up exactly where you left off.

The app checks the same host for updates and notifies you in-app when a new version ships.
FAQ
Windows says "Windows protected your PC" — is this safe?
New downloads without an established code-signing reputation can trigger SmartScreen. Click "More info" → "Run anyway". Signed builds are on the roadmap, which removes this warning.
How does activation work?
After purchase you receive a license key by email. In the app, open Settings → License, paste the key and click "Activate this device". The license is tied to that machine; deactivate in the same panel to move it.
Does it work offline?
Yes. Licenses re-validate in the background and keep working offline for a two-week grace period.
Can I use one license on two computers?
Each license includes one device seat. Additional seats can be added to your license — contact support after purchase.
