Documentation updates, README changes, and blog drafts go through multiple revisions. Tracking what changed between versions -- a rewritten paragraph, a broken link, a removed section -- is tedious when you are staring at raw Markdown. When a PR touches docs, you need to review content changes with the same rigor as code changes. Missing or incorrect documentation erodes trust and creates support burden.

Frequently Asked Questions

Can PowerDiff compare README files from different branches?

Yes. Copy the README content from two branches and paste them into PowerDiff to see every change in headings, links, code blocks, and prose. This is useful for reviewing documentation PRs outside of GitHub.

Does it highlight Markdown syntax like headers and links?

Yes. PowerDiff provides Markdown syntax highlighting through the Monaco editor. Headers, links, bold/italic text, code blocks, and lists are all visually distinct, making it easy to review structural changes.

Can I compare blog post drafts in Markdown?

Absolutely. Paste two versions of your blog post to see exactly what content was added, removed, or rewritten. This is perfect for editorial review workflows and tracking changes across revisions.

Is my documentation content kept private?

Yes. PowerDiff runs entirely in your browser. Your Markdown content, internal documentation, and unpublished drafts are never sent to any server.
