Lixing Wubi Keyboard
Read full descriptionHide full description
Lixing Wubi Keyboard is a fully offline Wubi (五笔字型) input method powered by a self-developed on-device engine. It supports three Wubi schemes—86, 98, and New Century. It requires no network permission and tracks, collects, or uploads no data at all. Three Wubi Schemes, Switch Anytime 86, 98, and New Century each ship with their own dictionary. Switch in Settings and your candidate ranking follows immediately—no need to adopt someone else's coding habits. 26-Key and 9-Key Layouts Beyond the full keyboard there is a 9-key Wubi layout: a 3×3 grid that makes one-handed typing on a phone far steadier. Each layout keeps its own key positions, candidate bar, and haptics. Smart Sentence Input A built-in language model assembles whole sentences as you type—more accurate, fewer duplicate codes, smoother input. No more disassembling long chat messages character by character. Picked the wrong segment inside a long sentence? Fix that segment directly instead of retyping the whole thing. Smart Wubi Guidance Valid next keystrokes are highlighted while invalid ones fade out, so you can always find the next key at a glance. Great for beginners. Dedicated Number Pad A separate number and symbol panel with the same key-by-key layout as mainstream Pinyin keyboards, so you never have to switch apps to do the books. Type an expression or a unit and it hands you the result. Semantic Candidates Type "tomorrow" and get the date, "3pm" and get the time, "12000" and get 12K, "12+34" and get 46. Domain Lexicons 16 vertical packs—emoji, chat, campus, legal, and more—switchable on demand. Professional and emerging vocabulary becomes typeable the moment you enable it, without disturbing your everyday candidates. Million-Word Dictionary Everyday chat, work, and life vocabulary is fully covered: common words, idioms, names and places, internet slang—whole-sentence candidates form in one pass. Keyboard Themes 6 built-in themes—Dark and Classic Gray (free), plus Liquid Glass, Rainbow, Sexy, and Peach. Every key recolors live when you switch, WYSIWYG. Slide Input & Swipe-Up Popups Full QWERTY layout with continuous slide input and dual-label number/letter keys. Long-press a letter and swipe up to open a punctuation or emoji panel in a grid. Font Size & Learned Lexicon Key label size, candidate text size, and candidate bar height are all adjustable to fit any screen and reading habit. The keyboard learns the characters and words you actually use—and Settings shows you exactly what it learned. Absolute Privacy Unlike other keyboards that demand "Full Access", Lixing Wubi needs no such permission—the keyboard extension has zero network access and is system-isolated, eliminating data leakage at the root. One-Time Purchase A single purchase unlocks every feature and all Pro themes forever. No ads, no tracking, no data collection. An optional yearly subscription is offered purely as a voluntary support plan—it never locks any feature.
