Text diff checker: frequently asked questions
Is my text uploaded?
No. The comparison runs in your browser, so confidential documents stay on your device.
Can it compare word by word?
This version compares whole lines. Put each sentence on its own line for a finer comparison.
What does a text diff show?
Additions, deletions and changes between two versions of text.
Can I compare code?
Yes. It compares any plain text.
Does it ignore whitespace?
Trailing whitespace and line endings can create differences; normalise them if needed.
Can I compare Word documents?
Paste the text; formatting is not compared.
Does it support Arabic?
Yes. Arabic text is compared correctly.
How do I compare contract versions?
Paste the old and new text to see every change; check legal changes with a lawyer.
Is there a size limit?
Very long documents may be slow on older phones.
Does it support Arabic text?
Yes. Text is processed as Unicode, so Arabic and other scripts are handled correctly.
