免費線上文字差異和比較工具
使用視覺差異可以更快地比較兩個版本的程式碼、設定檔或文件。 Dokall 突出顯示字元、單字或行層級的新增和刪除，以便您可以立即發現變更。
開發人員使用文字差異工具進行程式碼審查、配置審核和合併衝突解決。貼上兩個版本，選擇比較模式，然後查看突出顯示的輸出 - 所有這些都在瀏覽器中本地處理。
Frequently Asked Questions
What is a text diff?
A text diff compares two versions of text and highlights what was added, removed, or changed. Green typically means additions, red means deletions. Diffs are used in code reviews, document editing, and version control systems like Git.
What is the difference between line, word, and character diff?
Line diff compares entire lines - best for code and structured text. Word diff highlights changed words within lines - useful for prose and documents. Character diff shows every single character change - most granular, best for spotting typos and small edits.
Can I compare code with this tool?
Yes. Paste the original and modified code into the two panels. Use line-level diff for structural changes or character-level diff for spotting single-character bugs. For large files, dedicated tools like git diff are more practical, but this works well for snippets and config files.
Is my text sent to a server?
No. Dokall compares text entirely in your browser. Neither version is uploaded or stored. This makes it safe for comparing confidential code, configs, or documents.
How is this different from Git diff?
Git diff compares file versions tracked in a repository and shows changes between commits or branches. Dokall's text diff compares any two pasted text blocks without version control. Use Dokall for quick ad-hoc comparisons; use Git diff for tracked codebases.
