Three quick steps.
Snap it
Snap the page or upload a photo you already have. Your browser reads the text right there, nothing leaves your device.
Tap words
Tap any word, or several at once, right on the image. Each gets its own definition based on the exact sentence it's in, not a random dictionary entry.
Own it
Saved words come back right before you'd forget them, mixed across a few quiz styles so review never feels repetitive.

What Gloss actually looks like.
Stop taking screenshots you'll never revisit.
Every word you save is sorted into new, learning, and learned automatically, with struggling words flagged so you know exactly what to focus on.
See proof you're actually improving, not just guessing.
A daily streak and a 14-day review history keep momentum visible, so showing up becomes the habit, not the chore.
Two ways to practice.
