About 是语输入法
Sime is a fully offline Chinese Pinyin input method.
It supports full Pinyin and T9 layouts, local phrase learning, emoji, clipboard
history, quick phrases, and a local GRU sentence reranker. Input and candidate
ranking remain on the device; the app has no network permission, tracking, or
advertising SDK.
The F-Droid build does not include the optional handwriting recognizer because
its training-data redistribution terms are not suitable for F-Droid.
What's new in 0.17.2
Fix English word spacing in both Chinese and English keyboard modes.
