Paste the original and revised text to find changes in wording, numbers or paragraphs. Replacements appear as a deletion followed by an addition. Formatting and document layout are not compared. This English version accepts pasted text; file uploads are available on the Vietnamese version.
Frequently asked questions
What is the limit?
Up to 50,000 characters per side, with additional limits on comparison complexity. Split very different documents into smaller sections if needed.
What does ignoring whitespace do?
It normalizes whitespace within matching tokens; in line mode it also trims line edges. It does not guarantee that adding or removing a whole whitespace token is ignored.
Are my texts uploaded?
No. Comparison runs in a worker on your device. Text is inserted as text, not rendered as HTML.
