What this does
A standard diff over the two inputs, with additions and removals marked inline.
Limits
- Plain text only. No syntax awareness and no three-way merge.
Is this private?
Yes, and you can check rather than take our word for it. Open your browser's network tab and run the tool: your file never appears in it, because there is no server to send it to. The whole site is static files.
