Online text diffing with real-time highlighting and bi-directional editing, for code reviews and document comparison.
How to Use
Paste the original text
Put the first version into the left editor pane β type it in, or paste it from a file.
Paste the version to compare
The right pane holds the text you want to check against the original. Both panes stay editable, so you can correct a line on the spot.

Frequently Asked Questions
- What does the comparison detect?
- It compares the two panes line by line and highlights inserted, deleted and modified lines. It reports differences β it does not merge the texts or resolve conflicts for you.
- Is the text I paste sent to a server?
- No. The comparison runs inside your browser using an editor component that loads with the page. Nothing you paste is uploaded or stored.
- Can I keep editing while comparing?
- Yes. Both panes remain editable and the highlighted differences update as you type, so you can fix one side and see the effect immediately.
- Is there a size limit?
- The tool sets no limit of its own. Very large documents are bounded only by the memory your browser has available, and highlighting can get slower on files of many thousands of lines.
