Lumen first gets the site to show its own dark theme, whether that theme is driven by JavaScript or only by CSS. If the page is still light, it inverts it and puts photos and video back to their real colors. Inversion keeps the original contrast, so anything readable in light stays readable in dark.

Order

Site's own dark theme first, inversion only as a fallback

Fallback

invert(1) hue-rotate(180°) contrast(0.9), with the exact inverse on media

Modes

Auto, Dark or Off, remembered per site

Steady keeps movies from whispering one minute and shouting the next. It lifts quiet dialog, tames explosions and leaves silence alone. It works on the tab's audio, so it also works on Netflix and other protected players.

Measured

A 34 dB swing in becomes 1.9 dB out on a dialog–explosion–dialog scene

Timing

Turns down in ~0.15 s, back up in ~1.2 s

Control

One comfort slider, from Quiet to Very loud

Hush stops videos and audio that start playing with sound on their own, on every site. Muted background videos keep playing, and anything you start yourself plays. Once you've started something on a page, its playlist carries on.

Stops

Autoplay with sound, and videos that unmute themselves

Allows

Silent autoplay, anything you click or key, and the playlist after it

Shows

A count on the toolbar icon of what it stopped on this page

Glide scrolls at a steady reading pace, whether the page scrolls the window or a panel inside a web app like Gmail or Notion. At the end of an infinite feed it waits for more to load before stopping. Cinema mode lays every image and video out in one full-screen strip.

Speed

10–900 px/s, the same on 60 Hz and 120 Hz screens

Stops

At the end of the page, or when you press Esc

Cinema

Tuned for Reddit, 9gag, Tumblr, Pinterest and Imgur; a generic scanner everywhere else

Murmur plays rain, ocean waves and brown, pink or white noise to work, study or wind down to. The sound is generated in your browser, so there's nothing to download, and it keeps playing with the popup closed.

Sounds

Rain, waves, brown, pink and white noise, mixed with a slider each

Presets

Focus, Calm and Sleep

Timer

15 minutes to 90, fading out over the last 20 s
