About TextDiff

Compare two texts and see every change instantly, computed locally in your browser.

• Line mode: classic added/removed lines with an LCS diff
• Word mode: inline highlights of the exact words that changed
• Options: ignore case, ignore whitespace, trim line edges
• Live stats: added / removed counts and a similarity percentage
• Save snapshots, reload or delete them anytime; copy the result as a patch-style text

在中英界面下逐行或逐词对比两段文本，标红删除、标绿新增，实时显示相似度。支持忽略大小写/空白、保存对比快照、一键复制结果。所有计算全部在本机完成，文本永不上传。
