Capacities vs Roam Research

Capacities is a personal knowledge management app built around structured, typed objects (notes, people, projects, books, etc.) rather than a flat pile of documents. Users start from daily notes and create custom object types as needed, and the app automatically surfaces connections between related content instead of requiring manual backlinking for everything.

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.
