The common thread

One Wheel under all four jobs

Whatever the job, you reach the tools the same way. Hold Ctrl+Space (see every SHARA hotkey) and the SHARA Wheel opens at your cursor with six slices: Magnifier, Draw, Color, Erase, Shape and Screen. Release on a slice to pick it. A quick tap pins the Wheel open instead. Prefer a fixed spot? The docked toolbar holds the same tools.

  • Learn it once. The Wheel an instructor uses in a VS Code lesson is the one a teacher uses over a PDF.
  • Your eyes stay on the content. The Wheel opens where you’re already looking, not in a far corner.
  • Hidden on camera. Optional Presenter Mode keeps the Wheel out of recordings, so viewers see the ink appear, not the menu.

Every install starts with a 14-day Pro trial, so you can test the Pro rows in your own lesson, call or recording. Free forever tier. SHARA Pro is a $19.99 one-time lifetime license with a 14-day money-back guarantee, usable across your personal Windows devices via the Microsoft Store.

On every page

What stays the same, whatever your job

CALLS AND RECORDERS

Seen where you share

Overlays render on a system layer captured natively by Zoom, Microsoft Teams, Google Meet and OBS. The optional Presenter Mode keeps the Ctrl+Space Wheel out of recordings. Camtasia Recorder captures the overlays too. In Zoom or Teams, share your entire screen: a single-window share doesn’t capture SHARA’s overlay.

NO ACCOUNT

Nothing to sign up for

SHARA runs on your PC with no telemetry or analytics, online or offline; the network is used only to buy or restore Pro. That makes it an easy yes on managed work laptops and school PCs.

EASY RESET

A clean screen in a keystroke

The first Esc puts your ink in idle, so it stays on screen while you use your apps normally. A second Esc erases all ink and shapes. Ctrl+Win+B clears everything at once, and Ctrl+Z undoes it.

Install once, and every use case on this page works from the same Ctrl+Space Wheel or docked toolbar.
