What is this Tool?
Diff Viewer is a powerful text comparison tool that helps you track changes between two versions of text or code. It highlights additions, deletions, and modifications using industry-standard colors (Green for added, Red for removed).
Whether you are a developer reviewing code, a writer checking drafts, or a student comparing notes, this tool visualizes every single character difference instantly.
How to use
- Input Data: Paste your original text on the left and the modified version on the right.
- Analyze: The tool automatically computes the differences. Scroll through the result to see exactly what changed.
- Switch Views: Use Split View to see files side-by-side (like GitHub) or Unified View to see changes inline (like `git diff`).
Why do you need it?
- For Developers: Debug code regressions by comparing a working version with a broken one. Spot subtle typos that human eyes might miss.
- For Writers: Compare a revised contract or article against the original to ensure only approved changes were made.
- No Uploads: We respect your intellectual property. Your sensitive code/contracts are processed 100% in your browser and never sent to any server.
FAQ
Q. Is personal information safe?
Yes. We use a local JavaScript-based diff engine. Your data remains in your browser's memory and is discarded as soon as you close the tab.
Q. What does 'Split' vs 'Unified' mean?
Split view shows two parallel columns, which is great for comparing entire files. Unified view mixes lines together, which is often more compact for reading small changes.
