Markdown viewer for Mac Markdown,

Does your AI write
hundreds of Markdown files?

Plans, specs, research notes, handoffs. Coding agents write them faster than you can open them. Keep Pagewide beside the terminal and read each one as it lands.

  1. 1

    Open the project folder

    New files appear in the sidebar the moment your agent writes them. Open pages update in place, at your scroll position.

  2. 2

    Read, don't edit

    No cursor to nudge and no raw syntax. Pagewide never writes to your files, so it never trips up the agent. Wide comparison tables fit the window.

  3. 3

    Follow the references

    "Per 03_ §4.2" becomes a link. Point at it to preview the section, click to open it right there.

Works with Claude Code, Codex, Cursor, or anything else that writes Markdown. CLAUDE.md, AGENTS.md and plan files show up rendered, not raw.

Features

Made for reading.
Nothing in the way.

No editor pane, no raw syntax, no cursor. Write in whatever you like; Pagewide shows the result the moment you save.

Tables that never scroll sideways.

Wide tables span the page and wrap every cell, so you read the whole row at once. Long links and code break where they must, and nothing pushes the page wider. How it works.

Notes that link themselves.

Write "see 04_ §2.3" the way you always do. With a folder open, Pagewide turns file shorthand and section numbers into links: point at one to preview the section, click to open it right there. When several files match, pick the right one in the preview. Nothing to set up. How references work.

Full width

No narrow reading column. Text and tables use the whole window, with margins you can tune.

Live reload

Save in any editor and the page updates in place. You stay exactly where you were.

Open a folder

A project's Markdown as a tree in the sidebar. It updates as files come and go.

Tabs your way

A tab bar on top, or a list in the sidebar. Drag to reorder, ⌘1 to ⌘9 to jump.

Eight themes

GitHub, Serif, Sepia, Night and more, switched instantly. Add your own CSS too.

Find, zoom, print

⌘F to find, ⌘= to zoom, and Save as PDF that keeps your theme's type.

Safe by design

Markdown can't run scripts, load frames or send forms. Read-only, always.

Any text file

Open any text file read-only: Markdown is rendered; code, data and plain text files are shown exactly as written.

Folders & Tabs

Your whole folder,
one window.

Open a folder with ⇧⌘O and its Markdown appears as a tree. Click a file to open it in a tab. The tree follows along, and live-updates when files are added or renamed. Need two files at once? Put them side by side in one tab.

Peek

Point at the sidebar button to slide the sidebar over the page. Click it to keep it open.

With the sidebar hidden, a narrow strip of lettered tiles shows each open file

Letter tiles

Hide the sidebar and every open file stays one click away, as a tile with its first letter.

Two files side by side in one tab, a plan on the left and the rollout it links to on the right

Split view

Right-click a tab and choose Show in Split View to read it beside the one you're on, with a divider you can drag. Split Tab puts them back in tabs of their own.

  • ⇧⌘O Open folder
  • ⌃⌘S Show or hide the sidebar
  • ⌘1…⌘9 Jump to a tab
  • ⌃⇥ Next tab
  • ⌘W Close tab
  • ⌥⌘] Next theme

Themes

Eight looks.
One keystroke.

Pick one from View › Theme, or step through them with ⌥⌘]. Your place on the page stays put. Every theme follows light and dark mode, except Night, which is always dark.

FAQ

Questions about Pagewide.

Can I edit Markdown in Pagewide?

No, and that's on purpose. Pagewide is a viewer. Keep writing in the editor you like; Pagewide reloads the page the moment you save.

Which Macs does it run on?

Any Mac with macOS 12 Monterey or later. It's a universal app, native on both Apple silicon and Intel.

Is it an Electron app?

No. It's built with Apple's AppKit and WebKit, which is why it's under 2 MB and opens instantly.

Which files can it open?

Any text file, read-only. Markdown is rendered, in all its usual spellings (.md, .markdown, .mdown, .mkd, R Markdown .rmd, Quarto .qmd), with YAML front matter as a quiet block at the top. Code, data and plain text files (.py, .json, .yml, .csv, .log, .txt and the rest) are shown exactly as written. Images, PDFs and other binary files stay in Finder.

Can I change how it looks?

Yes. Pick one of eight themes, add your own stylesheets to the themes folder, or put small tweaks in a custom.css that applies on top of every theme. Press ⌘R to see your changes.

Does it send any data anywhere?

No. There's no account, no analytics and no tracking. The only time Pagewide touches the network is to show images that your Markdown links to.

How do I make it the default for .md files?

In Finder, select any .md file and press ⌘I. Under "Open with", choose Pagewide, then click "Change All…".

Your Markdown deserves the whole window.
