Example
Input (left vs right)
Left: first line second line third line Right: first line second line modified third line
Output (line-based diff)
first line - second line + second line modified third line
Note
Default is line-based diff. Even small changes within a line show as `-` then `+`. Toggle between split (side-by-side) and unified (inline) views.
Usage / FAQ
When to use
- Compare two versions of a config file, log, or email quickly
- Place two AI outputs side by side and inspect differences
- Self-review your own changes before a code review
- Verify translation consistency between drafts
- Toggle split vs unified view depending on what's easier to read
FAQ
- Q.Are whitespace and newlines counted as differences?
- A.Yes. Line-based diff means trailing spaces and CRLF vs LF show up. Trim the input first if you want them ignored.
- Q.Can I get a word- or character-level diff?
- A.This tool uses line granularity. For finer diffs, compare a single line, or use json-diff for structured JSON values.
- Q.What about very large texts?
- A.Thousands of lines work fine. Multi-megabyte input is not recommended since processing happens in the browser.
