Moonstone is a browser-native Markdown PKM workspace. Wikilinks, backlinks, graph view, and the same .md vault shape you already use — no install, no extension, no admin prompt. Bring your Dropbox, OneDrive, or Google Drive folder, or start fresh in Moonstone Cloud.
Linked notes are not a filing system. They are a surface for thinking. Each [[wikilink]] is a hypothesis about how two ideas belong together.

Looking for an Obsidian web app?
Obsidian is a beloved desktop Markdown PKM tool — but there is no official Obsidian for the web, no Obsidian on Chromebook, and no Obsidian that runs inside a locked-down browser. Moonstone fills that gap without asking you to change how you already work.
You keep
.md files, wikilinks, backlinks, tagsYou drop
Moonstone is an independent product and is not made by, endorsed by, or affiliated with Obsidian. “Obsidian” is a trademark of its respective owner and is used here only to describe a compatible Markdown vault workflow.
Product tour
The editor, the sidebar, the graph, the search — all running in your browser, against a real Markdown vault. No desktop binary required.
Folders, tabs, and backlinks laid out like a proper desktop PKM tool — no install, no extension.
Source stays plain text; inactive syntax fades so the writing stays front and center.
Watch clusters emerge from wikilinks, backlinks, and tags as the vault grows.
Open a Dropbox, OneDrive, or Google Drive folder as a live Markdown vault.
Jump to any note in a keystroke. Full-text results stay local and instant.
Reusable note scaffolds with variables for title, date, and time — right from the editor.
Bring your own cloud
Bridge Mode treats the folder you already trust as the source of truth. Moonstone layers the PKM workspace on top, without copying notes to a second home. Prefer zero setup? Moonstone Cloud is one click away.
Bring your Obsidian-style Dropbox vault to the browser
Open the Markdown folder you already keep in Dropbox.
Bridge Mode reads and writes .md files directly in your Dropbox account. Cursor-based deltas mean cached vaults reopen in milliseconds.
Use Moonstone as a browser front-end to your OneDrive vault
Read and write the Markdown that lives in OneDrive or SharePoint.
Bridge Mode connects through Microsoft Graph, hydrates images through authenticated downloads, and re-uses existing folders instead of duplicating them.
Open an Obsidian-style vault out of Google Drive
Open a Drive folder of .md notes as a live Moonstone vault.
Bridge Mode pages through Drive for Markdown and attachments, streams private files as blob URLs, and re-uses existing files by ID instead of duplicating them.
Managed — zero setup
Sign in and get a vault. No provider account required.
Clerk-backed auth, per-user Supabase row-level security, canonical attachment paths, and offline-first sync. The zero-setup path.
Why Moonstone
Desktop tools are powerful but unavailable on managed corporate machines, school laptops, and shared devices. Moonstone closes that gap without asking you to give up linked thinking or Markdown ownership.
Open a serious linked-thinking vault on any Chromebook, work laptop, library PC, or shared device. No extensions, no installer, no admin prompt.
Your notes are plain .md files with readable filenames and vault-relative paths. Export is a first-class path, not a hidden escape hatch.
Wikilinks, backlinks, tags, full-text search, and graph view turn loose notes into a dense web of ideas you can actually navigate.
Connect Dropbox, OneDrive, or Google Drive and edit the Markdown you already have. Moonstone layers the workspace on top instead of forcing a migration.
Edits stay fast on flaky connections. Changes queue to IndexedDB, sync resumes when you reconnect, and manual save is always one shortcut away.
Clerk-backed auth and per-user Supabase RLS scope every vault. In Bridge Mode, note content never touches our servers.
Bridge Mode
Moonstone connects to Dropbox, OneDrive, or Google Drive and reads the Markdown there as a live vault. Notes stay provider-side. Metadata stays minimal. Migration stays optional.
Moonstone Cloud
Sign in, get a vault, start writing. Clerk-backed auth, per-user Supabase isolation, and offline-first sync so edits survive the commute.
Built for
You already think in Markdown and wikilinks. Moonstone gives you the same workflow on machines where installing software is not an option.
Skip the plugin maze. Sign in, get a vault, start writing. The defaults are chosen for writing, not configuration.
Move between a laptop, a borrowed desktop, and a phone without syncing a binary. The browser is the runtime.
Frequently asked
Short answers to the questions people ask before creating an account.
Yes. Moonstone is a browser-native Markdown workspace with the same shape as an Obsidian vault — plain .md files, wikilinks, backlinks, tags, and graph view. Bridge Mode lets Moonstone open the Dropbox, OneDrive, or Google Drive folder where your vault already lives, so you can keep working on it from any browser without installing software. Moonstone is an independent product and is not affiliated with Obsidian.
That is exactly who Moonstone is built for. It runs entirely in a modern browser tab, so it works on Chromebooks, managed corporate machines, shared library PCs, and any device where you cannot install desktop apps. There is no extension, no installer, and no admin prompt.
No. Moonstone is not made by, endorsed by, or affiliated with Obsidian. It is an independent Markdown PKM app that runs in the browser. We describe it as Obsidian-style because it is built around the same workflow patterns — Markdown files, wikilinks, backlinks, tags, and graph view — not because it reuses the Obsidian codebase.
Plain Markdown (.md) files. Attachments stay as regular images and PDFs in the vault, referenced with vault-relative paths. Export produces a folder you can open in any other Markdown editor, including Obsidian itself.
Sign in, pick Bridge Mode, and authorize the provider. Moonstone then asks you to choose a folder to treat as the vault root. From that point on, every note you edit in Moonstone is written back to that folder in your own provider account. Moonstone stores only connection metadata on our side; your notes stay with your provider.
Yes, there is a free tier that covers the full editor, wikilinks, tags, graph view, and Bridge Mode against the providers you already use. Moonstone Cloud storage upgrades are available on paid plans.
