使用方法

  1. Paste the original text into the left panel and the modified text into the right panel。
  2. Toggle options to ignore whitespace, ignore case, or trim lines before comparing。
  3. Read the unified diff view: lines prefixed with + are additions, - are removals, and unmarked lines are unchanged。
  4. Check the stats bar for the total count of added and removed lines。
  5. All diffing runs entirely in your browser — nothing is sent anywhere。

範例

  • Pasting "hello world" on the left and "hello earth" on the right shows one removed line and one added line with the changed word highlighted。
  • Enabling ignore-case means "Hello" and "hello" are treated as identical and produce no diff output。
