Every update.
Every millisecond won.
SHARA started as a dedicated cursor highlighter built for pure speed. Today, it is an on-demand presentation and screen-annotation system — hardware accelerated, distraction-free, and designed to stay completely out of your way.
Instant Annotation Hide, Background Magnifier Pipeline & Synchronized Follow
When presenting live, you frequently need to reveal clean content behind your notes without erasing your train of thought. SHARA v4.3.2 introduces a seamless 3-way Erase tool that toggles annotation visibility instantly, paired with an isolated background magnification pipeline that prevents UI micro-stutters.
- Instant Annotation Hide: A new 3-band Erase tool (
All,Eraser,Hide) across both the Wheel menu and docked Toolbar. Temporarily hides all ink strokes with zero performance penalty. Annotations automatically reappear the moment you resume writing, clear, or press Undo. - Laser Stays Active: The Laser pointer remains fully functional while ink is hidden, letting you point out details on the clean desktop without revealing previous drawings.
- Custom Shortcut & Mouse Triggers: Assign dedicated hotkey chords or mouse buttons to instantly toggle ink visibility from Settings → Annotation Display.
- Dedicated Background Rendering: Offloaded screen magnification to an isolated background processing thread, eliminating frame drops on the main UI when zooming into live applications.
- Synchronized Lens & Halo: Optical synchronization locks the cursor halo directly to the center of the magnified disc, eliminating optical lag and motion desync on 120Hz and 144Hz displays.
- Responsive Dragging: Slashing drag follow lag by over 70% during high-speed mouse sweeps.
- Accidental Canvas Wipe Guard: Added a rest threshold on the Wheel’s Erase All slice. Quick flick gestures naturally select standard Eraser, preventing accidental wipes of your entire drawing.
- Pen Stroke Safety: In-flight pen strokes cleanly commit when summoning the Wheel, preventing background apps from intercepting taps.
- Smoother Scroll Scaling: Rapid mouse wheel scroll notches are gracefully coalesced for silky zoom adjustments.
The Docked Floating Toolbar, Direct Stylus Mode & First-Run Tour
While educators love the Ctrl+Space Wheel because it leaves their display completely uncluttered, many users requested an always-visible companion for dedicated whiteboard sessions. Version 4.3.0 introduces an elegant screen-edge docked Toolbar alongside direct Windows Ink tablet reading and an interactive first-run tour.
- Docked Floating Toolbar: Docks smoothly to any edge of your screen with every annotation tool one click away. Includes automatic collapse, edge-snapping, and bidirectional sync with the Wheel menu and global hotkeys.
- One-Click Wheel Switch: Switch instantly between the Toolbar and the Wheel with a dedicated toggle button.
- Direct Hardware Tablet Mode: Reads pens and graphics tablets in Windows Ink mode directly without converting through mouse lag. Includes resting palm touch filtering to prevent accidental clicks or interrupted lines while writing.
- Physical Eraser Flip: Inverting your Surface Pen or active stylus automatically switches to the Eraser tool, restoring your previous tool the moment you flip back to write.
- Interactive Onboarding Tour: A guided first-run experience that teaches you the gesture rhythm, radial shortcuts, and cursor halo customization in under 60 seconds.
- Settings Ergonomics: Unified modifier and shortcut assignment rows into clean cards that fit comfortably on 1080p laptop screens.
In-App Checkout & Perpetual Pro Lifetime Deal
We firmly reject recurring subscriptions for desktop utility tools. Version 4.2.9 streamlined our licensing system into a transparent, one-time lifetime purchase with zero telemetry and full offline verification.
- Theme-Adaptive In-App Checkout: Upgrade to SHARA Pro directly within the app via a sleek, secure checkout sheet powered by Paddle with instant license activation.
- Clear Trial Countdown: Transparent 14-day Pro trial indicators with no credit card required upfront. Free features continue working indefinitely once the trial concludes.
- Offline License Fallback: Zero network dependencies after activation. Your tools work reliably offline in classrooms, flights, and secure enterprise environments.
Transparent Wheel Backdrop & Fullscreen App Detection
Presenting over dark IDEs, video feeds, or dense documents requires maximum visibility without visual obstruction. Version 4.2.6 refined presentation ergonomics with transparent wheel backdrops and automatic fullscreen gaming detection.
- Transparent Wheel Backdrop: Set the radial wheel backdrop to transparent by default, allowing you to see your underlying content and code clearly without a dark dimming disc.
- Fullscreen Gaming & Presentation Auto-Detection: Automatically adapts cursor halo rendering when running exclusive fullscreen games or presentation decks to prevent visual clipping.
- Multi-Monitor Coordinate Normalization: Pixel-accurate bounds clipping and DPI normalization across mixed display scaling (such as a 4K 150% laptop alongside a 1080p 100% projector).
The Generous Free Plan: Permanent Core Presentation Freedom
A pivotal milestone in SHARA’s evolution: we permanently restructured our product tiering to make our headline presentation tools 100% free forever. No watermarks, no stroke limits, and no time-bombed trial lockouts on essential tools.
- Free Presentation Essentials: The complete SHARA Radial Wheel, Pen drawing, Laser pointer, Eraser, Straight Arrow, and the basic Cursor Halo are completely free forever for every user.
- Clear Pro Creative Depth: Reserved SHARA Pro for advanced creative capabilities: Translucent Marker (highlighter), geometric shapes (rectangles, circles, lines), 4-slot instant color switching (Alt+1–4), Live Magnifier Lens, and Keystroke Visualizer Tutor.
- Straight-Line Snap: Hold Shift while drawing to snap perfectly straight arrows and technical guide lines.
- Zero Paywall Traps: Fixed free color leaks and ensured free users never encounter sudden paywall popups while using their core tools.
The Ctrl+Space Radial Wheel Menu: Clutter-Free Presentation
SHARA’s major transformation. We asked ourselves: why do annotation apps force presenters to keep a bulky floating bar on screen that covers their content and breaks their eye contact with the audience? Version 4.0 replaced clutter with the signature Ctrl+Space Radial Wheel.
- Zero-Clutter Radial Architecture: Hold Ctrl+Space and your complete toolkit appears directly at your mouse pointer across six slices: Magnifier, Draw, Color, Erase, Shape, and Screen. Select a tool and release. It leaves nothing on screen.
- Flick vs. Latch Modes: Hold and flick for sub-second muscle memory tool selection, or tap to latch the wheel open when teaching interactively.
- Outer Color Ring: Rapidly switch between colors and line widths directly within the natural sweep of your cursor.
Screen Inking Engine & 144Hz Direct Composition
Traditional desktop overlays suffer from micro-stutter when the CPU is loaded during gaming, compilation, or video rendering. In v3.0, we introduced direct screen drawing alongside a hardware-accelerated compositor visual engine.
- Screen Drawing Engine (The Pen Tool): Draw directly over any active Windows application, presentation deck, or video with custom ink colors and stroke thickness.
- Direct Composition Visual Engine: Cursor halo and drawing motions are bound directly to the Windows Desktop Window Manager compositor, delivering buttery-smooth 60Hz, 120Hz, and 144Hz+ tracking with zero CPU lag.
- High-Capacity Stroke Buffer: Expanded real-time stroke buffer to 2,500 strokes with instant undo and canvas clearing.
- Dynamic Border Styles: Dashed and dotted animated halo borders with kinetic tilt physics and perspective warping.
Tutor Keystroke Visualizer, Picture-in-Picture Magnifier & Laser Pointer
SHARA expanded from cursor tracking into a comprehensive live presentation utility, giving teachers, video creators, and remote teams the tools to explain technical ideas clearly.
- Tutor Pill (Live Keystroke Visualizer): Displays shortcut chords and typed commands cleanly at the bottom of the screen with customizable fade delays.
- Automated Privacy Shield: Automatically suppresses keystroke display whenever focus enters a password field, ensuring sensitive credentials never appear on stream.
- Picture-in-Picture Magnifier Lens: Real-time magnified disc following the cursor with customizable zoom factors.
- Spotlight Dimmer: Dims the surrounding desktop while keeping a circular spotlight on your active demonstration area.
- Laser Pointer: High-visibility laser trail with customizable persistence for screen guidance.
- Native Master Hotkey: Low-latency global input hooks that prevent hotkey collisions with system shortcuts.
The Genesis: A Pure, High-Speed Cursor Highlighter for Windows
Where it all began. SHARA was conceived and packaged for the Microsoft Store as a dedicated Windows utility with one pure focus: solve the frustration of losing your mouse pointer during presentations, tutorials, and multi-monitor workflows.
- High-Contrast Cursor Halo: A vibrant, translucent focus halo following the mouse pointer across all Windows applications with customizable geometry (circles, squircles, rhombus) and border styling.
- Tactile Click Cues: Distinct visual ripple effects for left and right mouse clicks so tutorial viewers never miss an action.
- Privacy First: Packaged via the Microsoft Store with zero analytics, zero network tracking, and zero advertising.
