A Japanese-language study tool that photographs marked-up pages, extracts only the highlighted words, and builds Anki cards with translations, pronunciation, example sentences, and images.

Tangoru targets a very specific annoyance: the labor of turning a textbook page into a useful vocabulary deck. Its example page detects nine words and exports them as an image-enhanced .apkg file, with a free tier and a ¥780 monthly Pro plan.
