Made for readers who annotate.

Most documents die in a downloads folder. We wanted a quieter place to open them, mark them up, and hand them back — without installing anything or losing our notes to a proprietary format.

Marginal is a small tool built by people who read a lot: whitepapers, contracts, syllabi, long-form reporting. It runs in the browser, syncs to the cloud when you sign in, and keeps your annotations portable.

We're in preview. Every early user gets Pro features, and the feedback you send shapes what ships.
