Is my Markdown uploaded to a server?

No. The diff is calculated entirely in your browser. Your Markdown never leaves the device, which keeps drafts and sensitive content private.

Which views does the Markdown comparison support?

You get a rendered diff, a side-by-side rendered preview, and a word-level source diff. You can also export an HTML report or copy a unified patch.

Can I export the Markdown comparison?

Yes. Export a standalone HTML report with the styling, copy a unified patch, or download the differences as a Markdown file with ins/del markers.

How to compare Markdown

Paste or open your Markdown

Paste two Markdown documents or open .md files from your device. The comparison runs entirely in your browser.

Compare the views

Click Compare and switch between a rendered preview, a side-by-side view, and a word-level source diff to see changes the way you prefer.

Review and export

Scan added and removed passages, then copy the diff or export a Markdown report. Ignore whitespace and case to focus on real content changes.

What you can compare

Use it for READMEs, documentation, changelogs, blog drafts, specifications, or any Markdown. Switch between a rendered diff, a side-by-side preview, and a source-level diff to review changes at the level that fits the edit.

Rendered, side-by-side, or source

The rendered view shows the visual difference as you would read it. The side-by-side view compares the two rendered previews panel by panel. The source view shows the raw Markdown changes at word level, so formatting tweaks and wording edits are both easy to spot.

Flexible inputs

Type or paste directly, open .md files from disk, or paste from your clipboard. Ignore whitespace and case to focus on real content changes, and use the previous/next navigator to move through edits quickly.
