Plume
Opens with one double-click
Plume registers itself for .md, .markdown, .mkd and five more extensions. A second file opens in a new window of the running app — no cold start.
New Plume 1.0.1 is out
Markdown, beautifully set.
Double-click any .md file and it opens instantly — no vault,
no project, no editor chrome. Just the document, typeset the way it deserves.

Why Plume
A reader, not another editor.
Every Markdown app wants to own your notes. Plume just opens the file you clicked, renders it properly, and gets out of the way.
Reads Obsidian notes properly
Wiki links, embeds and section transclusion, callouts, ==highlights==, #tags, block ids and front-matter Properties — all rendered the way Obsidian does it.
Full GitHub-flavoured Markdown
Tables, task lists, footnotes, definition lists, emoji shortcodes, syntax highlighting, KaTeX math and Mermaid diagrams — rendered, not escaped.
Sidebar and outline
The folder tree around your file — the whole vault when the note lives in one — and an outline of every heading, with an honest reading time.
Live reload that keeps your place
Save the file in any editor and Plume updates in place — same scroll position, same spot on the page. Write in one window, read in the other.
Safe with files you did not write
Documents are sanitised, scripts never run, and links never launch programs. A note cannot make Plume pull files off other machines on your network.
Screenshots
Light or dark, it reads like a book.
Set the theme, the text size, the reading width and the typeface once. Plume remembers.
For Obsidian users
Your vault, without opening the vault.
Share a note with someone who does not run Obsidian, or just read one note without waiting for a whole workspace to load. Plume speaks the same dialect.
- Wiki links —
[[note]],[[Note#Heading|alias]], and they resolve across the vault. - Embeds and transclusion —
![[image.png|300]]and![[Note#Section]]. - Callouts —
> [!tip], including the foldable> [!warning]-kind. - Properties from front matter,
#tags,%%comments%%and^blockids. - Open in Obsidian for vault files, when you do want the full thing.
Everything else
The small things you expect.
Find in page
Ctrl+F, with next and previous and a match count — the way a browser does it.
Back and forward
Follow a link between notes and walk back out, with Alt+← or your mouse side buttons.
Print and export to PDF
On white paper, with a real PDF outline built from your headings.
Open in your editor
Jump into VS Code or Cursor if you have them, or the system text editor. Ctrl+E.
Images and code
Click an image for a lightbox; every code block gets a copy button that copies what you can see.
Keyboard first
Sidebar, text size, reload, new window, full screen — all on keys you already know.
| Action | Keys |
|---|---|
| Open file | Ctrl+O |
| Find / next / previous | Ctrl+F, Enter, Shift+Enter |

Plume Vault
Your notes, on every machine.
Plume reads the files already on your disk — that part is free, forever, and needs no account. Create one anyway and you get a vault: sync a document from your laptop and open it on your desktop, or in any browser.
100 MB, free with an account
Thousands of notes. Sign up with an email and a password — no card, no trial clock, no telemetry.
Sync from inside Plume
Sign in once under ⋯ → Plume Vault. Push the open document, or let every save go up by itself.
Yours, and private
Documents sit in private storage no one else can list. Passwords are hashed with scrypt. Nothing is indexed, shared or sold.
