Text Diff Checker
Paste an original and an edited version to see additions and removals highlighted line by line.
About this tool
When you've edited a document, contract, or piece of code and want to know exactly what changed, eyeballing two versions side by side is slow and unreliable. This tool compares an original and edited version line by line and highlights additions and removals.
How to use it
- Paste the original text into the left box.
- Paste the edited version into the right box.
- Click compare to see line-by-line additions and removals highlighted.
Tips
- This compares whole lines, so a small change to a long line will still flag that entire line as changed — split into shorter lines for finer-grained diffs.
- Great for catching accidental deletions when merging two versions of the same document.
- Works well for comparing two drafts of an email, essay, or short config file.
FAQ
Does it show word-level differences within a line?
