Open source · for org-roam
Your second brain, wherever you are.
Mycelium is a fast, beautiful web app for reading, editing, linking, capturing and planning with your org-roam notes straight from your git repository or cloud storage — on your phone, tablet or any computer. No Emacs required, and nothing about your files changes that you didn’t change.
Works with GitHub, GitLab, Bitbucket, Dropbox, OneDrive and Nextcloud · Add it to your home screen on iOS and Android
Everything org-roam is good at, in your pocket.
Byte-exact edits
Changes are applied as tiny text patches to your original files. Spacing, line endings and syntax we don’t understand stay exactly as Emacs left them.
Backlinks & graph
Every id: link, alias and ROAM_REF is indexed locally, so backlinks with context, unlinked mentions and the node graph are instant.
Capture & dailies
Jot a thought into today’s daily note in two seconds, follow org-roam’s file naming, and create linked nodes as you type.
Agenda that respects org
TODO keywords per file, SCHEDULED and DEADLINE, CLOSED stamps, habits and all three repeater styles behave the way org-mode does. See it as a list, a week, a month or a board, filtered with org’s own match syntax.
Plan your day or week
Drag tasks onto a timeline, a day at a time or a whole week side by side. Effort estimates become work sessions spread over several days, all written as plain org timestamps Emacs’ own agenda shows.
Quick add, triage, review
Type “Call Sam tomorrow 3pm #work ~30m” and it becomes a proper org task. Clear your inbox one card at a time, then walk through a weekly review of what’s overdue, waiting, stuck and done.
Made for your thumb
Swipe a task right to finish it or left for the actions you choose, hold and drag to reschedule, and get reminders on your phone. Add it to your home screen and it works offline.
Your git, or your cloud
Sign in with GitHub, GitLab or Bitbucket and you commit, pull and push when you choose. Or keep notes in Dropbox, OneDrive, SharePoint or Nextcloud and they sync on their own.
Private by design
No accounts, no database of yours on our side. Tokens stay on your device and the sync server keeps nothing but the encrypted reminders you opt into.
How it works
- 1
Connect your notes
Sign in with GitHub (choosing exactly which repositories it may use), GitLab or Bitbucket, or with Dropbox, OneDrive or a WebDAV server such as Nextcloud.
- 2
Your vault is kept in your browser
Your notes are copied into the browser’s private storage and indexed: nodes, links, tags and tasks. After your first visit it opens and works with no connection.
- 3
Edit, then sync
With git, edits save to your working copy; you review the changes, commit, pull and push when you’re ready. Cloud folders sync a few seconds after each edit. Conflicts are shown side by side, never silently overwritten.
