Why I built Margin
Here is the problem I kept running into. I spend a lot of my work day inside a browser, and every time a thought showed up, a task, a link to read later, something someone said on a call, I would open some separate notes app, jot it down, and then basically never see it again. The note would drift into a pile somewhere and get lost.
One day it reminded me of school. That habit of scribbling in the margins. That is the whole idea behind Margin. Your notes live on the one page you open all day long, your new tab. Open a tab and yesterday's thought is right there in front of you, grouped into sections and laid out as cards.
It runs fully on your device. No account, no sign in, no analytics, no servers. Nothing leaves your machine unless you export it yourself.
