DigMyGem

Open-source language reader

Every word you learn becomes a gem.

Read anything in the language you are learning. Each word you save starts as rough stone and, review by review, is cut into a real gemstone.

A saved word turns from rough stone into a cut gem, one stage at a time.

Read what you would read anyway.

No canned lessons. Open a news article, a novel, a PDF, subtitles, a YouTube transcript or a Reddit thread in the language you are learning. Tap any word to see what it means, and keep it.

A Spanish passage in the reader. Tapping a word shows its meaning: pescador, fisherman; muelle, pier; gaviotas, seagulls.

112 real gemstones to collect.

Every gem is a real mineral, from agate to zoisite. Its page in the Gem Wiki stays a numbered silhouette until one of your words reaches Brilliant. Then its artwork, story and facts are yours.

Practice that plays like a game.

The words you saved come back as games. Every right answer banks visible progress toward the word’s gem, and FSRS decides when the word returns, so nothing is repeated for its own sake.

A word earns progress with each right answer in a different game, and FSRS schedules its next review in four days.
