Free Online Text Diff Tool
Compare two text documents to see exactly what changed. Our diff checker highlights the differences word-by-word, making it easy to spot additions and deletions between versions of an essay, code snippet, or article.
How to Use It
Paste your original text on the left and the edited version on the right — added and removed words are highlighted instantly. Switch between an inline merged view or a side-by-side view, both with line numbers, using the toggle above the result.
Example
Comparing "The quick brown fox" with "The quick red fox jumps" highlights "brown" as removed and "red" and "jumps" as added.
Common Use Cases
- Comparing two drafts of an essay or article to see what was edited.
- Spotting changes between two versions of a code snippet or config file.
FAQs
Does it compare whole words or individual characters?
The comparison highlights differences at the word level, making changes easier to read than a character-by-character diff.
What's the difference between inline and side-by-side view?
Inline view merges both texts into one numbered passage with removals struck through and additions highlighted. Side-by-side view lists the original and modified text in two numbered columns, similar to a code review diff, so you can see each version's line numbers independently.
