Foam is a free, open-source note-taking application that uses a graph database to store notes as a network of interconnected ideas. It's designed to help users create a knowledge graph, where each note is a node that can be linked to other notes, creating a web of relationships between ideas.
Notion is a single space where you can think, write, and plan. Capture thoughts, manage projects, or even run an entire company.
Free for individuals; paid plans start at $10/user/month for teams.
