How to compare two texts and find the differences
Two versions of the release notes, a regenerated config against the old copy, a contract clause that feels different — paste both texts and the changes light up: what was removed, what was added, and what stayed exactly the same.
Step by step
Open the text diff tool
Start the free comparator — both texts stay on your device.
Paste the original text
Drop the before version into the first field.
Paste the revised text
Drop the after version into the second field.
Choose word or line mode
Word mode suits prose and small wording edits; line mode suits lists, logs, and configuration where a whole row is the meaningful unit.
Review the highlighted diff
Removed and added segments are highlighted with counts for each; copy a simple prefixed change listing to share the result.
Tips that save a second try
The comparison is exact, including case and whitespace — “Draft” and “draft” count as a change.
Moved text shows up as a removal plus an addition; the copied listing is a readable change list, not a unified-diff patch.
Very long or heavily line-broken documents can exceed the comparison matrix (2,000,000 token cells) — split the text or use a dedicated diff program for those.
Common questions
Is the comparison case-sensitive?
Yes. For example, “Draft” and “draft” are treated as different tokens and appear as a removal and an addition.
When should I choose line mode instead of word mode?
Use line mode for lists, logs, or configuration where a whole row is the meaningful unit. Use word mode for prose and small wording edits.
