Sensory Magnus is a modern assistive magnification and reading tool, designed to support people with a wide range of visual difficulties — on your Windows PC and out in the world with your iPhone camera.
Magnus combines powerful screen magnification with flexible colour support and natural-sounding speech — a complete accessibility toolkit in one free app.
Full screen, lens, ruler, offset ruler, and horizontal or vertical split-screen — each designed for different reading and navigation needs.
Fine-tune from 1× to 8× in 0.25 increments with high-quality smoothing. Independent horizontal and vertical scaling available.
Apply colour tints independently to the magnified area and background. Includes greyscale and inverted high-contrast modes.
High-quality human-sounding voices will read any accessible text under your mouse — in Word, Edge, PDFs, and more. Live word highlighting included. Register for early access →
Direct links to Windows settings for mouse pointer size and colour, text cursor appearance, and system text size — all from one place.
Register Magnus to run at sign-in or on startup — your accessibility settings are active before you even log in to Windows.
Switch between styles instantly with Ctrl+Shift+Tab, and adjust magnification with keyboard shortcuts at any time.
Magnifies your entire screen from 1× to 8×. The simplest and most immersive mode for all-day use.
A magnifying lens follows your mouse. Resize freely and apply contrast tinting outside to remove distractions.
A magnified horizontal band follows your cursor — ideal for reading line by line with a tint above and below.
View the full document at normal size on one half while the area under your mouse is magnified on the other.
The same split-screen concept arranged left and right — useful for wider document navigation.
Like the Ruler, but offset from the mouse so the magnified view doesn't obscure what you're pointing at.
| Shortcut | Action |
|---|---|
| Ctrl+Shift+→ | Increase magnification level |
| Ctrl+Shift+← | Decrease magnification level |
| Ctrl+Shift+Tab | Cycle through all 6 view styles |
Set independent colour overlays for the magnified area and the background outside it. Choose from a full colour wheel, adjust opacity, or switch to inverted high-contrast mode — with or without magnification.
Magnus Reader will add natural-sounding human voices to Sensory Magnus — reading any accessible text under your mouse in documents, web pages, PDFs and more. Not yet released — but coming soon.
