How does the text diff compare works?

It splits text lines and performs a Longest Common Subsequence (LCS) search to identify exact insert, delete, and modify blocks.

Is there a file size limit for word counting?

Because processing runs in-browser, it is limited by your device memory. It easily handles text documents up to 5MB.
