What is Compare Text?
A text diff tool: paste the original and changed versions to see exactly what was added or removed, with counts.
How it works
The diff library computes line-level changes, and changed hunks can be expanded to word or character granularity for finer detail.

Examples
Spotting changes in drafts
Paste two versions of a document side by side and see the differences highlighted — at word or line granularity.
Common mistakes
Whitespace-only differences
Trailing spaces and line-ending changes can flood a diff with noise. A whitespace-ignore toggle filters those out.
Frequently asked questions
What diff algorithm is used?
A Myers-style line diff with word-level refinement for precise, readable highlights.
Can I export the comparison?
Yes — copy the unified-style diff text for sharing or tools.
