How long can the text be?
It can process text within your browser's memory limits. Normal documents and small to medium code files work fine.
How are differences displayed?
Additions are shown in green, deletions in red. You can switch between character, word, and line granularity.
Is the text sent to a server?
No. All processing is done within the browser. Nothing is ever sent to an external server.
Can I use it to compare code?
Yes. It can be used to compare any type of text — code, JSON, documents, emails, and more.
