About the Text Diff Checker

A text diff checker that compares two pieces of writing line by line and marks what was added or removed.

How to use the Text Diff Checker

  1. Paste the original text.
  2. Paste the revised text.
  3. Read the lines that differ.

What to check

The check is line by line. A small edit in a long line can mark the whole line.

Can I compare code?

Yes. Paste each version. The checker does not run the code.

Does it ignore spaces?

Spaces count. A line that only changed indentation still shows as a change.
