Online Text Diff Checker — Compare Two Texts Side by Side
Paste two pieces of text and see what changed with word or line diff modes, side-by-side controls, whitespace options, and patch export.
Best For
Use Text Diff when you need to clean, review, transform, or analyze writing directly in the browser. The page is designed around a focused workflow: bring in the draft, note, transcript, or block of text, make the adjustment or check, then copy, export, or reuse the cleaned text in your document, CMS, or workflow.
Most work happens locally in your browser, which keeps files and text on your device and makes quick repeat checks practical. Review the output, then copy, export, or reuse the cleaned text in your document, CMS, or workflow.
