文本对比：两段文本的差异一目了然

改配置、改代码、改文案，总要确认"我到底改了哪里"。这个对比工具把两段文本逐行对比，新增行绿色、删除行红色高亮，并统计增删行数，一眼看出所有变化。

典型场景

核对配置变更：线上配置和本地配置贴进去对比，找出被改的行。
代码评审：新旧版本代码对比，快速定位改动点。
文案校对：两版文案差别，绿红高亮比肉眼扫全文快得多。

特点

支持大段文本、中文内容，增删统计清晰。本地逐行比对算法，无需上传内容，适合处理敏感文本。

Text Diff: see what changed at a glance

Configs, code and copy change constantly — you always want to know "what exactly did I change". This tool compares two texts line by line, highlighting added lines green and removed lines red, with add/remove counts, so every change is obvious.

Typical cases

Config review: diff your production and local configs to find changed lines.
Code review: compare old and new versions to locate edits fast.
Copy proofing: spot the differences between two versions of a text at a glance.

Highlights

Handles large and Chinese text well, with clear counts. The diff runs locally — safe for sensitive content.
