A few useful details
Does this compare meaning or just text?
It compares lines of text, including whitespace. It does not assess meaning, correctness, or whether a change is an improvement.
Does it merge the two versions?
No. It produces a readable comparison. You decide which changes to keep in your original document.
Can I compare large documents?
This tool is for small documents, with up to 1,000 lines across both inputs. The size and line limits keep the comparison responsive in your browser.
