Local-first · zero install

A Markdown editor that runs in your browser

Open a folder and edit the .md files inside it. Every change saves to the real file, not an export, not a sync.

One .md file, three modes
Local-first

Every note is a real file you own

Once you pick a local folder, NoteLoom reads and writes the Markdown files inside it directly. The same .md opens identically in Obsidian, Typora, VS Code, or any other editor.

  • Plain .md files, CommonMark and GFM compatible.
  • Pair with iCloud, Dropbox, or Git. No extra sync to set up.
  • Ownership is yours. Stop using NoteLoom and every file stays put.

Three-mode editor

Three ways to see one file

Source, edit, and read: three equal modes, switch between them anytime.

Source

Every Markdown mark in full, with no hidden characters. Best for tables, code blocks, and frontmatter.

Edit

Bold, lists, and tables render inline while you type. The line under the cursor falls back to source.

Read

A clean read-only view, the way the note will look when it is done. Full CommonMark, GFM, and KaTeX.

It grows into a knowledge base

Start with one file. As your notes stack up, NoteLoom links them together, so your knowledge connects instead of scattering.

Links and backlinks

Type [[ and pick a note from autocomplete. Every note tracks who links back to it, and turns plain-text mentions into real links with one click.

Publish

Share a note as a page

Right-click a note or a folder and publish it as a public link. Whoever opens the link just reads it, with no install and no account. What goes out is a read-only copy; your original file never leaves your disk.

Update it anytime to refresh the page, or unpublish to take it down. Your local note is never touched.
