How it works
The tool finds the longest common sequence of lines between both texts. Lines only in the original are marked as removed; lines only in the changed version are marked as added.
Example
Comparing 'a, b, c' with 'a, x, c' shows 'b' removed and 'x' added.
Frequently asked questions
Does it compare words or lines?
Lines. Changed lines appear as one removal and one addition.
Is whitespace significant?
Yes. Enable 'ignore whitespace' to trim lines before comparing.
Is there a size limit?
The product of the two line counts must not exceed 1,000,000. For example, 1,000 lines per text. Compare larger texts in smaller sections.
