About the Text Diff Viewer
The Text Diff Viewer compares two pieces of text and highlights exactly what changed — what was added, removed, or modified between them. Instead of squinting line by line, you see the differences called out clearly.
Comparing versions is a constant need: two drafts of a document, two revisions of code, or a before-and-after of any text. A visual diff makes the changes obvious, so you can review edits, catch unintended changes, and understand what someone modified.
Comparison runs in your browser, so your text never leaves your device. That keeps drafts and code private while you diff them, with no upload or account.
How to use the Text Diff Viewer
- Paste the original text into the first input.
- Paste the changed text into the second input.
- Run the comparison.
- Review the highlighted additions, deletions, and changes.
- Use the highlighted diff to verify or merge the edits.
Common use cases
- Comparing two drafts of a document to see what changed.
- Reviewing edits someone made to your text.
- Spotting differences between two versions of a code snippet.
- Confirming that only intended changes were made.
Frequently asked questions
What kinds of differences does it show?
It highlights added, removed, and changed content between the two texts, so you can see precisely what differs rather than guessing.
Can I compare code as well as prose?
Yes. The diff works on any text, including code snippets, configuration, and documents. For side-by-side code comparison, the Code Diff Viewer is tailored to that.
Is there a length limit?
You can compare sizable blocks of text; very large inputs depend on your device’s resources since processing is local.
Is my text uploaded anywhere?
No. The comparison happens in your browser, so your text never leaves your device.
Does it merge the changes for me?
It highlights the differences so you can review and merge manually; it does not auto-merge, which keeps you in control of the final text.
