Frequently asked questions
Does it work for non-Markdown files?+
Best for Markdown. Plain-text files also work. Binary files don't diff usefully.
How do I share the diff?+
Copy the diff output and paste in PR comments, email, or chat.
What about word-level highlights?+
Currently line-based diff. Word-level diff is a future Pro feature.
