What is NoteLoom

What is NoteLoom?

NoteLoom is a browser-based, local-first Markdown editor. You open it in your browser, pick a folder on your computer, and read and write the .md files inside it directly. Your notes are saved as real Markdown files on your local disk, not uploaded to any server.

In short: open NoteLoom in your browser, point it at a folder on your computer, and edit the .md files inside it directly, switching freely between source, live, and reading modes.

Requires the desktop version of Chrome, Edge, or Arc; Firefox, Safari, and mobile are not supported yet.

What NoteLoom can do

  • Works right in the browser, no install or sign-up: open the web page and you are ready to go, with no client to download and no account to create.
  • Reads and writes local .md files directly: you pick a folder on your computer, and NoteLoom edits the Markdown files inside it, saving your changes back to the original files in real time, without going through the cloud.
  • Real files you can take with you anytime: your notes are standard .md files that any Markdown editor can open; one-click export to zip is supported.
  • All the features for organizing notes are built in: a file tree, multiple tabs, a document outline, links between notes, tags, and keyword search (full-text, including CJK/Chinese).
  • Browser extension: turn web page articles or YouTube and Bilibili captions into Markdown, preview them, then save them to your local folder.

The editor has three modes, and you switch the same note between them with one click (the names below are the actual ones used in NoteLoom):

Mode What it is
source mode See and edit the raw Markdown text directly, with symbols like #, ** all shown. Good for when you want to see exactly what's there or make precise edits to the syntax.
live mode (default) Renders your content into its formatted look as you write, with only the line your cursor is on revealing its raw symbols so you can edit them. It's not a split-screen preview, it's an in-place "write and watch it transform."
reading view Renders your note into a clean, formatted look for reading (no symbols visible), read-only with no editing.

What NoteLoom is not (clearing up common misconceptions)

To avoid any confusion, here is a clear list of what NoteLoom does not currently have:

What it isn't Details
Not a file converter It opens .md and .markdown files. Word documents, PDFs, and other formats are not read; getting them into Markdown is a separate step.
Keyword search, not a query language Search matches the words you type, CJK text included, across the folder you opened.
No cloud sync Local-first; your notes are never uploaded to NoteLoom servers. For multi-device sync, just put the folder in iCloud / Dropbox / Git.
No collaboration It's a personal local knowledge base, with no real-time co-editing.
Not desktop software It's a web app you use in the Chrome, Edge, and Arc browsers; Firefox, Safari, and mobile browsers are not supported yet.

Who NoteLoom is for

  • People who, because they use AI, have ended up with a .md file (maybe for the first time) and want an app to open, read, edit, and save it.
  • People who want "notes = real files on my own disk" and don't want to be locked into some cloud database.
  • People who use Chrome, Edge, or Arc and are happy to read and edit the .md files in a local folder directly in the browser.

FAQ

What kind of files does NoteLoom open?
Files ending in .md or .markdown, anywhere inside the folder you picked, subfolders included. Files and folders whose names begin with a dot are skipped, so entries like .obsidian stay out of the tree. Everything stays a plain Markdown file that any other editor can open.
How do I open and edit a whole folder of .md files in the browser without uploading them?
Open NoteLoom in Chrome, Edge, or Arc, then mount a folder from your disk. It reads and writes the real .md files in place and saves changes straight back to the original files, with nothing uploaded and no account. It uses the browser's File System Access API, so the files never leave your computer.
Is there a free browser-based Markdown editor that opens a local folder and saves back to disk, with no account?
Yes. NoteLoom is free, runs in the browser with no install and no sign-up, and opens a folder of .md files on your disk so you can edit them in place and save back to the original files. Your notes stay as plain Markdown on your own computer.
