MD Smarter – Markdown Viewer & Editor

MD Smarter turns Chrome into a clean, fast Markdown reader and editor. Open .md files from your computer, from any URL, or straight from a GitHub page — then read them beautifully, edit with live preview, and export to Word or PDF. Got a README from GitHub, notes from an AI tool, or docs from a teammate? Just click the MD Smarter icon. ━━━━━━━━━━━━━━━━━━━━ OPEN FROM ANYWHERE ━━━━━━━━━━━━━━━━━━━━ • Open local files (.md, .markdown, .txt) with one click, or drag & drop them onto the page • Paste any link to a Markdown file — GitHub file links are converted to raw automatically • On a GitHub .md page or a raw .md tab, click the toolbar icon to open it instantly • Local file:// tabs are supported too (after enabling "Allow access to file URLs") ━━━━━━━━━━━━━━━━━━━━ READ COMFORTABLY ━━━━━━━━━━━━━━━━━━━━ • GitHub-flavored Markdown: headings, tables, task lists, quotes, links and images • Syntax highlighting for code blocks • Outline sidebar — jump to any section, with the current section highlighted as you scroll • Light, dark, or follow-system theme ━━━━━━━━━━━━━━━━━━━━ EDIT AND SAVE ━━━━━━━━━━━━━━━━━━━━ • Three views: Read, Edit and Split (live preview side by side) • Save changes straight back to the original local file with Cmd/Ctrl+S • Online files can be saved as a new .md file on your computer • Unsaved-changes indicator and a reminder before you close the tab ━━━━━━━━━━━━━━━━━━━━ EXPORT TO WORD OR PDF ━━━━━━━━━━━━━━━━━━━━ • Word (.docx): keeps headings, bold/italic, links, lists, tables, code blocks, quotes and images • PDF: clean, print-ready A4 pages with no toolbars • Works for both local and online files ━━━━━━━━━━━━━━━━━━━━ PRIVATE BY DESIGN ━━━━━━━━━━━━━━━━━━━━ • Everything happens locally in your browser • No account, no analytics, no tracking, no servers • Website access is requested only when you open a link from a new site — and only for that site • All rendered content is sanitized to block malicious scripts ━━━━━━━━━━━━━━━━━━━━ FREE ━━━━━━━━━━━━━━━━━━━━ All features are free. If MD Smarter saves you time, you can support development from the ☕ Support page — Buy Me a Coffee for global users, Alipay for users in mainland China. Entirely optional.
