MarginNote vs Roam Research

MarginNote is a study and knowledge-management app for Mac and iPad, positioned as a place 'where deep reading leaves a trace.' It integrates PDF/EPUB annotation, mind mapping, and an FSRS-based spaced-repetition flashcard system so that highlights and notes automatically become study cards across multiple linked formats.

Roam Research is a web‑based note‑taking platform built around bi‑directional links and a graph view, allowing users to create a web of interconnected ideas. Its daily notes page encourages a habit of capturing thoughts as they happen, while the query language lets you retrieve information across the entire knowledge base. Designed for researchers, writers, and knowledge workers, Roam supports markdown, collaborative editing, and real‑time syncing across devices. The platform’s open API enables custom integrations and automation, extending its capabilities beyond personal use.
