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. **價格與方案:** DiffDuo is completely free: no sign-up, no account, no limit on the number of comparisons and no ads. Comparison runs locally in your browser. - **Split and unified views:** 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. - **Word-level highlighting:** Darker highlights mark the exact words and characters that changed inside a modified line, not just the lines that differ. - **Local, private processing:** The comparison runs entirely in your browser, so confidential code, contracts and config files never leave your device. - **Whitespace and case tolerance:** Ignore whitespace, indentation and capitalisation differences, and control how much unchanged context is shown around each change. - **Large-file handling:** Compares plain-text files up to 50 MB in a background thread, so pages with hundreds of thousands of lines do not freeze the UI. **優勢:** Runs fully in the browser, so sensitive text and code are never uploaded; Free with no sign-up, no usage limits and no advertising; Word-level highlighting makes edits inside a line easy to spot; Unified view matches git diff and patch format, including hunk headers **限制:** Limited to plain-text comparison, with no semantic or AI-based code review; No account, saved history or team collaboration features; Requires JavaScript to be enabled in the browser; No desktop or command-line client, so it is a manual copy-and-paste workflow [Profile (Markdown)](https://openaitools.app/tw/tool/diffduo.md) ## Knowt Knowt is a free study platform and the most popular Quizlet alternative, combining flashcards, note-taking, and AI study tools.
