Overview

Product summary

Review the store description, core capabilities, and common use cases.

Version 2.0.7: Upgrade to Manifest V3

Version 2.0.4: Bug-fixes and updated style.

As well as being a great general purpose screen dimmer, Visor's overlays and point of focus feature may be assistive to users with visual perceptual difficulties such as Dyslexia, Scotopic Sensitivity Syndrome and Visual Stress.

Whilst research shows results vary from person to person, some users may find that the use of overlays can help with fluency, eye-strain, concentration and comprehension whilst reading.

In addition to the traditional overlay method, Visor also employs a point of focus feature, designed to further reduce visual confusions and the tendency to skip lines.

This horizontal focal point tracks your mouse, giving full focus to the content being read, whilst reducing the visual noise of the surrounding page.

Es muy útil para personas que se no se logran concentrar fácil, como yo. Ayuda a enfocar la vista en determinado punto de lo que se quiera leer, la verdad es que me sorprendí con lo bien que funciona.

It works great but not on pdfs opened in the browser. The extension still kinda works but the highlighted portion doesn't move with my cursor, this problem only happens with pdfs and embedded documents.

The visor follows your mouse it cannot be set at one height. Annoying. Other than that it was great idea.

AI product read

Screen dimmer and reading aid that overlays a customizable colored tint on web pages with a mouse-tracking horizontal focus band

Helps users with visual perceptual difficulties (dyslexia, scotopic sensitivity syndrome, visual stress) reduce eye strain and improve reading fluency, concentration, and comprehension by dimming surrounding content and highlighting the area being read

User clicks the extension icon to activate. The popup appears with sliders for Red, Green, Blue (overlay color), Alpha (overlay opacity), and Focus (height of the clear reading band). The overlay tints the entire page, and a transparent horizontal band follows the mouse cursor, dimming everything except the line being read. Settings are saved automatically and persist. Clicking the close button on the popup removes the overlay from the current tab.

Target users: Users with dyslexia or visual perceptual difficulties / Users with scotopic sensitivity syndrome or visual stress / People experiencing eye strain from screen reading / Anyone wanting to reduce visual noise while reading online

Two image assets (visor-plus.png, visor-plus-large.png) exist in the assets folder but are not referenced in any source code — their purpose is unclear but they do not affect functionality.
The extension must be reactivated on each page load as stated in the store description (no persistent content script injection).

Monetization

No paid features detected

The extension has no payment UI, no billing APIs, no license checks, no feature gating, and no subscription logic. The 'upgrade' keyword hits are all from the third-party Material Design Lite library's CSS class names (e.g., .is-upgraded, .browserupgrade), not related to paid upgrades. The 'license' hits are Apache 2.0 license headers in the same third-party library. Two unused image assets (visor-plus.png, visor-plus-large.png) exist in the assets folder but are not referenced in any source code — they may be leftover or planned assets, but no code gates features behind them. All features (overlay color, alpha, focus tracking) are available to all users without any payment.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension is entirely local and self-contained. It uses chrome.storage.local for persisting user preferences, chrome.scripting for injecting overlay CSS/JS into web pages, and chrome.runtime for internal messaging. There is no authentication, no account creation, no network calls to external services, and no login UI of any kind.
