The Text Diff Checker compares two pieces of text side by side and highlights exactly what changed — additions in green, deletions in red. Use it to compare document versions, check edits, or spot changes between any two texts.
Frequently Asked Questions
What does a text diff show?
It shows additions (text in the second version that wasn't in the first) and deletions (text in the first version that's missing from the second).
Can I compare code?
Yes — it works with any plain text including code, documents, emails or anything you can paste.
Is there a character limit?
No hard limit — but very large texts may be slow to process in the browser.
