How it works

A walkthrough, end to end.

  1. 1

    Drag one or several markdown (.md or .markdown) files onto the drop zone, or press ⌘O to browse. Files load instantly — they're parsed in your browser using the marked library.

  2. 2

    Use the sidebar to reorder files (drag handles), rename them, or remove ones you don't need. The order in the sidebar is the reading order in the preview pane.

  3. 3

    Pick a reading theme — Dark, Sepia, Light or Dim — to match your environment. Word count and reading time are shown live in the header.

  4. 4

    Scroll through your files as one continuous document. Use the scroll progress bar at the top of the header to track how far you've read.

Use cases

What you can do with this.

Preview README files before pushing

Drop your README.md and confirm headings, code blocks and tables render the way GitHub will show them — without the commit-and-refresh dance.

Read documentation across multiple .md files

Drop an entire docs folder onto the drop zone. Reorder files in the sidebar to match your intended reading order, then scroll through everything as one continuous, themed document.

Convert markdown to PDF

Open the preview in your reading theme of choice, hit ⌘P (Ctrl+P), and Save as PDF — the print stylesheet generates clean, printable output without the editor chrome.

Sepia / dim mode for long-form reading

Reading 20-page specs in pure-dark hurts after a while. Sepia and Dim modes are tuned for hours-long sessions — easier on the eyes than dark and lighter than full white.

Compare drafts side-by-side

Drop the old and new versions of a markdown file. Use the sidebar to switch between them quickly without losing scroll position in the preview pane.

Read GitHub gists without GitHub's chrome

Download the .md from a gist, drop it into the preview, and read it cleanly — no header noise, no comments rail, just the rendered prose with reading-time and word count.

FAQ

Frequently asked.

  • Never. Files are read with the FileReader API and rendered locally with the marked + DOMPurify libraries. Nothing is uploaded.

  • GitHub Flavored Markdown — headings, lists, tables, fenced code blocks, task lists, links, blockquotes, images, and inline HTML (sanitized).

  • Use your browser's Print dialog (⌘P / Ctrl+P) and save as PDF — the preview pane is print-styled. A dedicated export button is on the roadmap.

  • Dark for late-night reading, Sepia for long-form prose, Light for daylight or sharing screenshots, Dim for low-eye-strain reading without going pure dark.

  • Yes — code blocks are rendered with proper monospace font, padding and a subtle border. Language-specific token highlighting is on the roadmap.

  • Because most real markdown reading is multi-file: book chapters, documentation sites, blog drafts. Reading them as one continuous flow beats opening N tabs.
