Put two Markdown revisions side by side and see what changed
Rereading a rewritten document rarely tells you what actually moved. Place the two revisions next to each other, let the changed lines show up in colour, and pull across only the changes you want to keep.
How to write it
The earlier revision
## Getting started

2. Write the bodyThis is the baseline. It can be a file you already have, or the document you are currently editing.
The rewritten revision
## Getting started
1. Open the page (no sign-up)
2. Write the body
3. Take it out as MarkdownHere line 1 gained a qualifier and line 3 is new. The comparison leaves the untouched lines alone and marks only those two places.
What this editor gives you
Only the changes stand out
The two revisions sit side by side with additions and deletions in distinct colours. Unchanged lines stay aligned, so your eye does not lose its place.
Pull a change across
Choose which changes to take while you read the comparison. There is no need to retype anything by hand.
The text is not uploaded
The comparison runs in the browser. Nothing reaches a server until you pick a place to save.
Frequently asked questions
How do I load the two documents?
Compare the document open in the editor against a downloaded file or one stored in GitHub or Google Drive. Two pasted passages work just as well.
Is the compared text sent to a server?
No. The comparison happens in the browser, and by default the only storage used is your browser's local storage.
Can I compare something other than Markdown?
Any line-based text can be compared. The result is displayed as Markdown, so text that reads as Markdown is the easiest to follow.
