Text Diff Checker

Paste two versions of a text and instantly see every added, removed and unchanged line — with character-level highlighting, word mode and one-click copy.

Modified text Version B
Unchanged Removed Added Inline + / - shows character changes

📋 Line diff

Compares your texts line by line with a clean side-by-side style list. Removed lines in red, added lines in green, unchanged in grey.

🔎 Character highlight

Changed lines also show inline red and green highlights for the exact characters and words that differ.

⚖ Flexible matching

Ignore whitespace or letter case to focus on meaningful changes — ideal for code reviews and document edits.

📤 Copy anywhere

Copy the full diff as plain text with + / - markers, or download it as a .txt file for sharing.
