Deckle for MAC
Free, open-source menu bar app that lays a subtle paper-grain texture over your whole screen to make long reading and writing sessions feel like paper.
Deckle Overview
Deckle is a free, open-source menu bar app that lays a subtle paper-grain texture over your entire Mac screen. The idea is to make long reading and writing sessions feel more like paper than glass. You pick a paper, set how strong it is, and keep working: the overlay is fully click-through, so every window underneath stays usable. It comes with 26 built-in papers, from a plain dimming veil with no grain to warm, tinted, dark and fiber-heavy finishes, and you can save up to eight named desk setups such as Read, Write or Unwind.
For people who want their own look, Paper Mill previews a new paper on your real desktop while you tune its tint, wash, weave, blotch, fibers and roughness, and shows estimates of contrast and blue-channel reduction as design guidance. Deckle is not a calibrated blue-light filter, and the developer says so plainly; it is a matte texture overlay. Version 2.0.0 adds Echo, an animated companion in the menu, and optional paper-cut desktop pets: Miso the cat and Tide the fish. Deckle is made by the independent studio Kelvanic and released under the MIT license. It needs macOS 13 or later, runs natively on Apple Silicon and Intel Macs, and release builds are signed and notarized by Apple.

Deckle FAQ
Is Deckle free?
Yes. Deckle is free and open source under the MIT license.
What does Deckle do?
It lays a subtle paper-grain texture over your whole screen from the menu bar, so long reading and writing sessions feel more like paper than glass. The overlay is click-through, so you can keep working normally underneath it.
Is Deckle a blue-light filter?
No. The developer describes it as a matte texture overlay, not a calibrated blue-light filter. Paper Mill shows estimated blue-channel reduction and contrast only as design guidance, not as a medical claim.
How many papers does Deckle include?
It comes with 26 built-in papers, grouped as quiet reading, papers, warm, tinted, dark and fiber-forward. You can also create your own in Paper Mill and export or import them as files.
Can I turn the texture off quickly?
Yes. Option-Command-P toggles the paper from any app, and you can snooze it for 15 minutes, 30 minutes, 1 hour or 2 hours. Compare original shows your bare screen for a moment without changing your settings.
Can Deckle stay off in certain apps?
Yes. Per-app rules let you show the paper everywhere, hide it while chosen apps are in front, or show it only while they are in front. Each display can also be included or excluded.
Will the texture show up in my screenshots?
Deckle can optionally hide the texture from macOS screenshots and recordings while it stays visible to you. macOS gives no guaranteed opt-out, so some screen-sharing and recording apps may still capture it.
Which macOS version does Deckle need?
Deckle needs macOS 13 or later and runs natively on both Apple Silicon and Intel Macs.
Is Deckle signed by Apple?
Yes. Release builds are signed with a Developer ID and notarized by Apple, so they open without a Gatekeeper warning. Deckle can also check GitHub for new versions and offer to update itself.
