dian puts vocabulary where you already look.
Add the widget to your home screen or lock screen, and a new word
appears — with its meaning, and its translation in up to three
languages of your choosing, side by side. No app to open. No lesson
to finish. Just a word, glanced at between other things.
Ten languages are available: Japanese, Korean, Mandarin Chinese,
Spanish, French, Vietnamese, Thai, Indonesian, Filipino, and Burmese.
Pick up to three at once — see how the same idea sits differently
across scripts and sounds.
dian doesn't gamify. No streaks, no quizzes, no notifications
nagging you back. It's a companion for people who already read, who
are already curious, and who'd rather let a language arrive quietly
than chase it with an app.
Every word includes a definition, an example sentence, and audio in
every language shown — tap once to hear it said properly. Dark mode
is done properly too, not just inverted.
The starter tier is free: one foreign language, common-tier
vocabulary, every theme and every translation feature included.
Upgrading unlocks up to three languages at once, the full
difficulty range, from common words to genuinely rare ones, and full audio for foreign examples.
