How it works
Compare two text blocks with readable line and inline changes.
Use it to compare two versions of plain text and locate additions, removals, and edits.
Example
Compare a configuration before and after a change to isolate modified lines.
Notes
- Desktop keeps the two inputs side by side; mobile stacks them.
- Changed lines get inline highlights while full additions and removals keep separate lanes.
- Patch export and merge flow are intentionally out of scope.
Constraints
- Compares text only; patch export and merge conflict resolution are out of scope.
- Limit: 512 KiB combined input. Nothing is uploaded or silently truncated.
Common errors
- Combined input over the limit
- Binary content
- Large generated single lines
When to use it
