よくある質問
Is this a character-level or line-level diff?+
Line-level. Each changed line is highlighted as a whole; character-level diffing is a planned upgrade.
Can I use it on code?+
Yes. The tool preserves whitespace and special characters. Very large inputs may slow down in-browser.
Is my text uploaded anywhere?+
No. The comparison happens entirely in your browser.
