Frequently asked questions
Does the checker compare line by line?
It preserves common text at the start and end, then labels changed middle lines as removed or added.
Are spaces considered differences?
Yes. Text is compared exactly, including whitespace and capitalization.
Can I compare long documents?
Yes, but the output is a simple line-based comparison rather than a character-level document diff.
Can I use this on a phone?
Yes. The two input panes stack on narrow screens and remain editable by touch.
Are either versions uploaded?
No. Both texts are compared locally in your browser.
