When two versions of something look almost identical, finding what actually changed by eye is painful. A text compare (diff) tool highlights every added and removed line for you in seconds.
How to compare two texts (step by step)
- Open the Text Compare tool.
- Paste the original on the left and the changed version on the right.
- Click Compare, additions and removals are highlighted, with a count of each.
How to read it: lines highlighted in the accent color were added; lines in red were removed; unchanged lines stay plain.
When a diff saves the day
- Document revisions, see exactly what an editor changed.
- Code review, compare two versions of a function.
- Contracts, catch a quietly altered clause.
- Config files, spot the one line that broke something.
Tips
- Compare line by line, keep matching content on the same lines for the clearest diff.
- Trim noise, remove irrelevant sections first to focus on real changes.
