文本对比

功能说明What It Does

文本对比工具可快速找出两段文本之间的差异，逐行高亮新增、删除与修改内容，帮助你比对代码、文档或配置文件的版本变化。

A text diff tool that spots differences between two texts, highlighting additions, deletions and edits line by line — perfect for comparing code, documents or config versions.

支持并排（Side-by-Side）与内联（Inline）两种视图，并能进行行内字符级高亮，让细微改动也无所遁形。

It offers side-by-side and inline views, plus intra-line character-level highlighting so even subtle changes stand out.

适合代码审查、合同 / 文档修订、配置变更核对等需要精确差异定位的场景。

Ideal for code review, contract/document revision and config change verification that need precise diff location.

粘贴即比对，无需上传，结果直观，是开发者与编辑的高频工具。

Paste and compare instantly with no upload; an intuitive result that makes it a go-to tool for developers and editors.

适用人群Who Should Use

开发者进行代码 review 与版本差异比对。

Developers doing code review and version comparison.

法务、编辑、产品等需要比对文档或合同修订的人群。

Legal, editorial and product people who compare document or contract revisions.

技术原理How It Works

采用逐行 + 行内字符级差异算法（如最长公共子序列）计算新增、删除与修改。

Uses line-level plus intra-line character diff algorithms (such as longest common subsequence) to compute additions, deletions and edits.

差异计算与高亮渲染均在浏览器本地完成。

Diff computation and highlight rendering both run locally in the browser.

安全与隐私Privacy & Security

两段文本仅在本地比对，不上传、不留存，可放心粘贴敏感内容。

Both texts are compared locally only, never uploaded or retained, so sensitive content is safe to paste.

使用步骤How to Use

1. 在左右两侧粘贴原始文本与修改后的文本。Paste the original and modified text into the two panes.
2. 选择并排或内联视图。Choose side-by-side or inline view.
3. 查看高亮出的新增 / 删除 / 修改行。Review highlighted additions, deletions and edits.
4. 必要时复制结果或继续调整。Copy the result or keep editing.
