Compare two text snippets side by side
A diff checker compares two text snippets and highlights the differences between them. It shows what was added, removed, or unchanged, similar to how Git shows changes between commits. This is invaluable for code review, document revision, and content comparison.
Unlike basic diff tools that only show line-level changes, our diff checker provides character-level precision. Changed lines are highlighted with a lighter background, while the exact differing characters within those lines are shown in a darker shade.
This makes it easy to spot exactly what changed — a single character, a word, or a complete rewrite.
Paste your original text in the left panel and your modified text in the right panel. The diff appears below, with red highlighting for removed content and green for added content.
Navigate between diff chunks using the ▲ and ▼ buttons on the right side, or use the ↑ and ↓ arrow keys on your keyboard. Click the arrows next to each changed line to accept or reject individual changes.
