About DiffScope
DiffScope is a focused diff tool: paste an original and a modified version of any text, and it shows you exactly what changed — line by line and word by word — in a split or unified view. It is built for code review, resolving merge conflicts, comparing configuration and tracking edits in documents.
Every comparison runs entirely in your browser. There are no accounts, no ads and no analytics that sell your behaviour. The text you paste — including source code under NDA, secrets and personal data — never leaves your device.
It is built and maintained by Interhive OÜ, a small studio in Tallinn that makes tiny, dependable web tools.
What it does
- Line-level diff
Compare two texts line by line with added, removed and modified lines colour-coded like Git.
- Word highlighting
Inside a modified line, see the exact words and characters that changed.
- Split & unified
Read changes side by side or inline with context, and switch instantly.
- Ignore whitespace
Hide formatting-only noise so only meaningful changes remain.
- Export patches
Copy the diff or download a standard .patch file to share or apply.
- Change navigation
Jump between changes and see a summary of added, removed and changed counts.
