Original

Modified

Compare Texts and Spot Differences Quickly

Paste two versions of a document and highlight what changed. It’s useful for proofreading, code snippets, and content reviews when you don’t want a full VCS workflow.

How It Helps

  • Proofing: Catch missed edits or unintended deletions.
  • Change review: Share a minimal diff instead of an entire file.
  • Migrations: Verify content transforms step by step.

Options

  • Ignore case and whitespace to focus on structural changes.
  • Swap sides to confirm the diff reads as intended.

Frequently asked questions

Can I diff large files?

The tool is best for snippets and moderate text sizes in the browser.

Does formatting matter?
