Obsidian turned a lot of people into note-taking converts with one simple idea: keep your notes as plain Markdown files on your own device, then link them to each other until they form a web instead of a pile. We built Noteweave to let you feel that exact loop right here, in your browser. Write a note in Markdown, watch it render live next to what you type, and link it to another note with double brackets. No install, no account, no signup.

How to use it
Two sample notes load the first time you open Noteweave, one of them showing basic Markdown and the other showing how two notes can link to each other. Tap the menu icon to open the notes list, tap the + button to start a new note, and use the pencil and trash icons next to any note to rename or delete it. The title field at the top names whichever note is open.
Write in plain Markdown: a line starting with # becomes a heading, **word** becomes bold, a line starting with - becomes a list item, and a line starting with > becomes a quote. Wrap a note’s title in double brackets, like [[Second brain]], to drop a link into the text. Click that link in the preview and Noteweave jumps to that note, creating it first if it does not exist yet. That’s the whole hook: write, link, and the notes start to form a web instead of a stack.
Every keystroke saves instantly. Everything you write, including which note you had open last, is stored only in this browser. Nothing is uploaded anywhere, and there are no accounts or notifications to manage.
How it compares to Obsidian
Noteweave keeps the part of Obsidian that actually drives the habit: plain Markdown editing, a live preview next to what you type, and the [[wikilink]] syntax that turns note titles into clickable jumps and creates the target note on the fly if it does not exist. That linking loop is the reason people who try Obsidian for a week end up using it for years.
What it drops is nearly everything else. There is no plugin ecosystem, so no Dataview queries, no calendar or task plugins, nothing to install or update. There is no graph view to see your whole vault as a node map. There is no Canvas mode for freeform visual boards. Sync does not exist at all: Noteweave lives in one browser on one device, while Obsidian can mirror a vault across your phone, tablet, and laptop through its paid Sync service or a self-hosted setup. There is also no folder structure, no tags, and no search across notes, since the point here is the core write-and-link loop, not vault management at scale.
So when should you get the real app? The moment you have more than a handful of notes and need folders, tags, or search to find anything. Or the moment you want the same vault open on your phone and your laptop. Or the moment a plugin like Dataview, a calendar view, or a Canvas board would genuinely change how you work. Noteweave is a fast way to feel out whether Markdown note-linking fits how your brain works. Obsidian is the tool built to hold that habit for years, across every device you own.
Get the full app
Obsidian is free for personal use, with sync and commercial licensing available as paid add-ons. If you have already decided the plugin ecosystem or the local-first design is not quite right for you, we also tested the best Obsidian alternatives, including options with built-in encrypted sync and real-time collaboration.
Frequently asked questions
Can I use Obsidian in a browser without downloading it?
Obsidian itself is a desktop and mobile app you install locally; there is no official web version. Noteweave, the tool on this page, needs no install and no account. It is our own original editor inspired by Obsidian’s write-and-link loop, and it runs entirely in your browser.
Is this the real Obsidian?
No. Noteweave is an original tool we built, inspired by the Markdown-and-wikilink workflow that makes Obsidian useful for millions of people. It is not affiliated with, endorsed by, or connected to Obsidian or Dynalist Inc. in any way. The download links above go to the official app.
Does my writing save if I close the tab?
Yes, on your device only. Every note and the one you had open last are stored in your browser’s local storage and reload exactly as you left them. Nothing is sent to a server, and nothing syncs to another browser or device.
Does it work offline?
Once the page loads, Noteweave makes no further network requests, so a dropped connection will not interrupt it. For notes that actually sync across your phone and computer, or a plugin ecosystem to extend the app, you need the real Obsidian.
Is it free?
Yes. Noteweave has no ads, no purchases, and no account requirement. Obsidian is also free for personal use, with paid tiers for its Sync and Publish services and for commercial use.
