Paste your original and modified text into the two panels, choose comparison mode (lines, words, or characters), and click Compare. Additions are highlighted in green, removals in red.
Can I compare by words instead of lines?▼
Yes. You can compare by lines, words, or individual characters. Word-level comparison is useful for finding small changes in paragraphs.
Is my text stored or uploaded?▼
No. All comparison happens locally in your browser. Your text is never sent to any server.
What types of text can I compare?▼
You can compare any text — code, essays, legal documents, configuration files, or any plain text content.
