Why DictoBoard
Three things that change how you type.
Learn as you type, in any app
Instant Word Definitions
Type any English word and its Chinese definition appears instantly in the candidate bar — no app switching, no copy-paste, no interruptions. From algorithm to serendipity, build your vocabulary without breaking flow.
Your keystrokes stay on your phone
Fully Offline, Private by Default
Everything runs on-device through a local SQLite dictionary with 210,000+ words. Zero network access for the keyboard — no keystrokes, no words, no data ever leave your phone. The internet is irrelevant.

Privacy
Your keystrokes never leave your phone.
