Online Text Diff Checker
Compare two blocks of text instantly. Powered by Google's diff-match-patch algorithm for precise, semantic highlighting of additions and deletions.
Why Use NoteRich Text Diff Checker?
Semantic Algorithm Powered
Built on Google's robust diff-match-patch library, this tool performs semantic cleanup before rendering. It groups scattered character changes into readable word or sentence chunks, preventing messy and confusing character-level noise.
Clear Visual Feedback
Additions are highlighted in green, and deletions are struck through in red. Get a quick summary of exactly how many characters were added or removed at a glance.
Seamless HTML Export
Export the comparison results directly as an HTML snippet with inline styles. Save it into your NoteRich workspace to maintain the exact visual highlighting of additions and deletions in your notes.
