Bright Spots, Dimmed. In Any App.

Preview, Mail, Safari, Pages — SuperDimmer works across your whole Mac. When a white document or page clashes with a dark workspace, it dims only that bright region. Your IDE, terminals, and dark UI stay exactly as they are.

White document · type here · dark mode cannot restyle this

This is a pure white page beside a dark IDE. Drag the amber bar — only this page dims. Close the window to park it as a desktop icon, then drop it in the Projects folder.

Works the same in Preview, Mail, Safari, Pages, and every other app.

Seven powerful features working together. Intelligent dimming, workspace management, and eye comfort—all automated.

SuperDimmer features: bright-region isolation, active window focus, color temperature, auto-hide

Per-Region Brightness Detection

Works inside any window, in any app. SuperDimmer finds regions that are starkly brighter than their surroundings and softens only those areas — so a white PDF, email, or webpage can sit next to a dark IDE without washing out the whole screen.

👻 Auto-Hide Inactive Apps

Apps you haven't touched for 5+ minutes? Hidden automatically (like pressing ⌘H). Keeps your workspace clean. Configure the delay or exclude specific apps.

Super Spaces HUD Compact Mode

Super Spaces HUD

Revolutionary floating HUD for managing macOS Spaces. Switch between desktops with keyboard shortcuts (Cmd+1-9), add notes to each Space, and see all your workspaces in a beautiful overview grid. Visual indicators show visit order and recent activity.

Progressive Dimming Visualization

Progressive Dimming

Windows progressively dim based on when you last used them, creating a clear visual hierarchy. Current window bright, recently used slightly dimmed, inactive windows fade further. Your workspace naturally guides your attention.

Idle-Aware Timers

Smart timer pause when you step away. Auto-hide, auto-minimize, and progressive dimming all pause during inactivity. Return to find everything exactly as you left it—no unwanted changes while you're away.

Every Feature You Need

Multi-Display Support

Works across all your monitors. Each display is analyzed and dimmed independently.

Configurable Grid Precision

Idle Detection

All timers pause automatically when you step away. No unwanted auto-hide or dimming changes while you're idle. Everything stays exactly as you left it.

Per-Space Notes

Add persistent notes to each macOS Space. Remember what you're working on, track tasks, or leave yourself reminders. Notes sync across restarts.

How SuperDimmer Actually Works

Not a whole-screen dimmer. It watches every window, finds the bright regions that clash with your workspace, and softens only those areas.

1

Looks inside every window

Preview, Mail, Safari, Pages, Slack, Chrome — wherever you work. SuperDimmer is not tied to one app or document type.

2

Finds disruptive brightness

It identifies regions whose brightness stands out sharply against neighboring content — the white PDF page, the email body, the article pane you can’t restyle.

3

Dims only that region

A precise overlay covers the bright area. Chrome, toolbars, and already-dark UI stay clear so your layout and contrast remain readable.

4

Runs quietly in the menu bar

Install once, grant Screen Recording for analysis, set your threshold, and leave it on. Comfort follows you from app to app.
