What this tool does
Text Diff Checker compares original and changed text using line or word mode, then highlights additions, removals, and unchanged parts.
How it works
Paste both versions, choose line or word diff, and review the summary plus highlighted output. No text leaves the browser.
Useful for
- Comparing two drafts.
- Checking edited instructions.
- Reviewing small config or copy changes.
Limitations
The diff is designed for practical review, not a full version-control replacement for huge files or semantic code comparison.
Questions before the button mashing
Does it support word diff?
Yes, the word mode gives a practical token-level comparison for smaller passages.
Can I copy the full diff?
You can copy the summary, which is usually the useful part to share.
