Markdown became the place you think: clean, portable, often shared with an AI.
But the moment another person needs in, you’re back to cloud lock-in, heavy
apps, or ‘collaboration’ that quietly stops being markdown. Marcia keeps your
notes as plain .md files on your own machine, and lets other people write in
them alongside you.
Your notes, now with other people
Local-first by default
Your notes live on your own machine and open instantly, before the network gets
a say. Close the laptop, drop the wifi, the work is still right there, still
yours.
Real markdown, all the way down
What you write stays plain, portable text, not proprietary blocks you’ll fight
to export later. Switch between raw and rendered freely, and open it anywhere,
in anything.
Collaboration that feels immediate
See who’s in the note and watch edits land as they happen. Share, set access,
write together without giving up the offline, on-device part.
Light web, real desktop
The desktop app keeps a folder of .md files in sync on your disk and stays
fast. On a borrowed computer? The web client loads light, nothing to install.
