Compare two texts side by side and highlight differences instantly. Perfect for document comparison, version control, and content review.
Enter or paste both versions of your text to compare them side by side.
Text difference checkers compare two versions of text and highlight changes. Writers use them to track edits, developers review code changes, and teams verify document updates. The tool scans both inputs line by line, marks additions in green, removals in red, and keeps unchanged content neutral.
How it works: the algorithm splits text into lines, compares each line position, and flags mismatches. When lines differ, it shows the original with a minus prefix and the modified with a plus prefix. Identical lines display without markers. This visual approach makes version tracking simple for essays, contracts, and code reviews.
Practical uses include proofreading drafts, tracking document revisions, comparing configuration files, and reviewing collaborative edits. The side by side view helps spot typos, verify updates, and confirm changes before publishing. Students compare essay versions, editors review article changes, and developers check configuration updates.
