Why “Margin”
For centuries, the smartest readers thought in the margins.
Newton, Fermat, da Vinci: their breakthroughs weren't in the body text. They were scribbled in the margin, where reading turns into thinking. Marginalia is the oldest form of a second brain.
Then notes went digital, and the margin disappeared. Today most of us keep years of notes that quietly go to die, a graveyard we never reopen. Apple put AI in there, but it only sharpens the pen: rewrite this, summarize that, fix the grammar. It makes the tombstones prettier.
Margin brings the margin back. It doesn't polish your sentences. It thinks alongside them.
