Frequently Asked Questions
How does the text diff checker work?
Paste or type two versions of text and the tool compares them line-by-line, highlighting additions, deletions and changed lines in different colors.
Is my text sent to a server?
No. The comparison runs entirely in your browser, so your text stays private.
Can I use it for code comparison?
Yes. It works great for code files, configs, JSON, and any plain text — just paste both versions side by side.
