FAQ

What do the different colors mean?

The colors show the differences. Green is for text that has been added, red is for text that has been removed, and yellow is for lines that have been changed.

What is "side-by-side" vs "inline" view?

The side-by-side view shows the two texts next to each other. The inline view combines them into one and uses colors to show the changes. You can switch between them to see what works best for you.

Can I compare files?

Yes, you can upload two text files to compare them. The tool will show you the differences in the same way it does for pasted text. This is good for comparing different versions of a document or code.
