Markdown, polished without handing it away

Markdown often contains private ideas, client work, product specs, research, and AI output. markup is built for people who want beautiful previews without making upload-to-render the default.

Secure by Default

Your Markdown, filenames, diagram definitions, and math source are not sent to external rendering servers. Anonymous rendering statistics stay off unless you explicitly turn them on.

Local Technical Rendering

A bundled local rendering engine handles Markdown, syntax highlighting, LaTeX math, Mermaid diagrams, and supported PlantUML diagrams on your device, including environments where external rendering services are unavailable.

Built for Mobile Reading

Native rendering, landscape reading mode, dark mode, and PDF export are tuned for repeated mobile use, so Markdown can move from rough text to a clean artifact without leaving your device.

When working with ChatGPT or Claude, markup is my go-to previewer. It perfectly renders the AI-generated Markdown content, making it easy to review and refine outputs before sharing with clients.

Frequently Asked Questions

Everything you need to know about markup

Can I open existing Markdown files?

Absolutely! markup can open any .md or .markdown file from your device. Just use the file picker to browse and select your documents.

Which platforms are available?

Google Play, App Store for iOS, Mac App Store, and Microsoft Store releases are planned. Store entries are shown as Coming Soon until each listing is public.

Is there cloud sync?

No, markup focuses on local processing for privacy. Your files stay on your device. You can use your preferred cloud storage service to sync files between devices.

Does markup send diagrams or math to external servers?

No. LaTeX, Mermaid, and supported PlantUML rendering are handled locally on your device. The app does not send diagram or math source to external rendering services, and it does not rely on an external PlantUML server.

What does anonymous usage analytics collect?

Only rendering statistics such as Markdown block types and counts, app version, locale, platform, and subscription plan. File contents, filenames, and personal information are not collected, and analytics stays off unless you enable it.

What makes markup different from other Markdown apps?

markup is a dedicated previewer and polishing app, not a full editor. This focus keeps the interface calm, the rendering path local, and the output tuned for reviewing and sharing Markdown.

Can I customize the appearance?

Yes! Premium users can choose from 9 body fonts, 7 code fonts, and multiple syntax highlighting themes. Free users get our beautiful default theme.
