Description

A lightweight tool to mask parts of images directly in the Editor. Works on Mobile & Web!

Simple Mask solves the problem of "clutter" when creating image occlusions. Instead of generating dozens of new notes for a single image, it lets you draw masks directly onto your existing pictures.

It is non-destructive: it never modifies your original image file. Instead, it saves the masks as lightweight code hidden behind the image.

Key Features

📱 Works Everywhere: Because Simple Mask uses standard code, your masks work perfectly on AnkiDroid, AnkiMobile (iOS), and AnkiWeb.
👆 Hide All, Reveal One: Tap a specific mask to peek behind it.
🔓 Instant Reveal: Simply press the standard Show Answer button to make all masks disappear at once.
🎨 Flexible Shapes: Draw Rectangles, Circles, Triangles, and Hexagons in multiple colors.

How to Use
