About the Text Compare

Text Compare highlights the differences between two blocks of text line by line, so you can instantly see what was added, removed, or changed. It works like a lightweight diff viewer right in your browser.

Everything runs client-side โ€” your text never leaves your device, which makes it safe for comparing config files, contracts, code snippets, or any sensitive content.

Common use cases

  • Spotting changes between two versions of a document or config file
  • Reviewing edits before committing code
  • Comparing API responses or log outputs
  • Proofreading two drafts of an article or email

How to use the Text Compare

  1. Paste your original text into the first input box.
  2. Paste the text you want to compare into the second box.
  3. Review the highlighted additions and deletions in the diff output.
  4. Copy or adjust the text and re-compare as needed.

Frequently asked questions

Is my text uploaded to a server?

No. The comparison happens entirely in your browser, so nothing is sent or stored anywhere.

Can it compare large files?

Yes, it handles large blocks of text, though very large inputs may render more slowly depending on your device.

Does it compare character by character or line by line?

It compares line by line and highlights which lines differ between the two inputs.
