See exactly what changed between two versions
When two documents look almost identical, spotting the one line that moved or the clause that was quietly reworded is slow and error-prone by eye. This diff checker does it for you: paste the original and the changed version, and it highlights every addition and removal, line by line. It compares the text entirely in your browser, so nothing is uploaded.
How to compare
- Paste both versions: the original on one side, the edited text on the other.
- Compare: added lines are marked in green and removed lines in red, so the changes stand out at a glance.
- Review the result: scan straight to what moved instead of re-reading the whole thing.
What it is good for
Line-by-line comparison suits a lot of everyday jobs: checking what an editor changed in a draft, comparing two versions of a contract or terms of service, reviewing a code snippet, or confirming that a copied list matches the original. Because it works on plain text, it does not care where the content came from.
Private and part of a wider toolkit
Both versions stay on your device, which matters for contracts, code and anything sensitive. When you have found the differences you can clean things up with the other Etoolio text tools: remove duplicate lines, count words, or convert Markdown to HTML, all free and all in your browser.
