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 mode, Edit mode, and Reading view.
Requires the desktop version of Chrome, Edge, or Arc.
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
.mdfiles 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
.mdfiles 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. |
| Edit 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. |
Where NoteLoom fits (clearing up common mix-ups)
So there is no confusion, here is what NoteLoom works on:
| What it works on | Details |
|---|---|
| Markdown files | It opens the .md and .markdown files in the folder you point it at. Getting Word documents or PDFs into Markdown is a separate step. |
| Keyword search | Search matches the words you type, CJK text included, across the folder you opened. |
| The folder on your disk | Local-first: your notes stay in the folder you opened and are still there after you close the tab. To reach them from another machine, put that folder in iCloud, Dropbox, or Git. |
| One person's notes | A personal local knowledge base, on the machine you are on. |
| Your browser | It runs in Chrome, Edge, and Arc. |
Who NoteLoom is for
- People who, because they use AI, have ended up with a
.mdfile (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
.mdfiles 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.
