Crafted for clarity
Everything your viewers need to follow along effortlessly.
Tagsor stays out of your way until you move, click, type or annotate — running natively on Windows with near-zero CPU overhead.
Screen marker & smart shapes
Draw smooth Catmull-Rom curves over any window. Hold steady at the end of a stroke to snap into circles, rectangles, triangles, stars, lines, arrows or checkmarks.
Spotlight focus dimmer
Press Ctrl + Alt + S to softly dim the rest of your screen while keeping a clear circular spotlight locked onto your cursor.
Keystroke badges & repeat counter
Shows up to 3 recent keystrokes with crisp vector icons and stacks rapid repeats (×2, ×3) before morphing back to your name.
Multi-mouse profiles
Uses Windows Raw Input to tell physical mice apart. Give each a name and accent colour — Tagsor switches tags whenever that mouse moves.
Built-in password privacy
Anything typed into a Windows password box is never displayed, plus a global Ctrl + Alt + H shortcut hides keystrokes on demand.
Hold to snap
Scribbles in. Clean shapes out.
The screen marker smooths every stroke into a Catmull-Rom curve, and recognises the shape you meant when you hold still.
Snapped to Circle
Hold still 0.5 s → snap
Draw it rough. Tagsor cleans it up.
Pause at the end of a stroke and the screen marker recognises what you meant — no shape toolbar required. Pick a shape to watch it morph from a wobbly scribble.
Also recognised: ellipses and rectangles. Try them for real in the live playground.
Get started
From download to demo in three steps.
Step 1
Download the .exe
Grab Tagsor.exe from the latest release. It is a single self-contained file — no installer and no .NET runtime to set up.
Step 2
Run it
Double-click Tagsor.exe. A small icon appears in your system tray and your cursor tag shows up straight away.
Step 3
Present, record, pair
Use Ctrl + Alt + D to draw, Ctrl + Alt + S to spotlight, and Ctrl + Alt + 1 / 2 / 3 for status chips. Esc dismisses everything.
Private by design
It shows your keys. It never keeps them.
Fully offline
The app contains no networking code. There is no telemetry, no analytics and no account.
Keystrokes stay in memory
Keys are rendered on the pill and forgotten. Password fields are skipped, and Ctrl + Alt + H hides keys on demand.
One tiny local file
The only thing saved is your mouse names and accent colours, in a JSON file in your own AppData folder.
Make every cursor easy to follow.
Free, open source and entirely local. Download the single executable and be presenting in under a minute.
