以多種講解風格解釋程式碼,並提供複雜度分析與重構建議的 AI 程式助手
同一段程式碼可用機器人、5 歲小孩、初學者、教師、NASA 程式設計師等風格講解,結果可直接複製。
分析演算法複雜度,找出沉重迴圈、昂貴操作以及難以維護或執行緩慢的程式碼。
在保持專案對外行為不變的情況下,改寫雜亂程式碼以提升可讀性與結構。
掃描程式碼中隱藏的缺陷與安全問題,並在上線前提供改進建議。
DiffDuo is a free online diff checker that compares two texts, files or code snippets directly in your browser. It shows removed lines in red, added lines in green and highlights the exact words that changed, in either a side-by-side split view or a git diff-style unified view.
Read changes in two columns side by side, or switch to a single-column unified diff in the same format as git diff and patch files.
Darker highlights mark the exact words and characters that changed inside a modified line, not just the lines that differ.
The comparison runs entirely in your browser, so confidential code, contracts and config files never leave your device.
Ignore whitespace, indentation and capitalisation differences, and control how much unchanged context is shown around each change.
