What it does

Built for people who work with text

Developers copying docs. Writers saving articles. Researchers feeding AI tools. CleanMark handles the messy part.

⚡

One-Click Extract

Uses Readability.js (same as Firefox Reader View) to strip ads, navbars, scripts, and noise. Just the content.

📝

Proper Markdown

Headings, bold, italic, lists, code blocks - all converted correctly. Not just plaintext with # symbols.

👀

Live Preview

Side-by-side editor shows raw markdown and rendered preview. Edit before you copy.

🔒

100% Private

Everything runs locally in your browser. Zero data sent anywhere. No analytics, no tracking, no servers.

FAQ

Common questions

CleanMark uses Mozilla's Readability.js - the same algorithm Firefox uses for Reader View. It identifies the main content and strips away everything else (ads, navigation, popups, scripts), then converts the clean HTML to markdown.

Yes. You get 3 extracts every day with all features. The counter resets at midnight. For most casual users, this is enough. PRO just removes the daily limit.

100%. CleanMark runs entirely in your browser. No data is sent to any server. We don't track usage, collect analytics, or store your content. The extension doesn't even have network permissions.

It works on most content-heavy sites - articles, blogs, docs, news. Some heavily JavaScript-rendered SPAs or login-gated pages may not extract perfectly.

After purchasing, you'll receive a license key via email from Gumroad. Open CleanMark, click "Upgrade", then "I have a license key", paste it, and click Activate. That's it.

Refunds are handled case-by-case for technical issues. We recommend trying the free tier first to make sure it works for your use case. See our refund policy for details.
