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.
Reflect is a networked note-taking application built around backlinks, so every note can connect to related notes and build up a personal knowledge graph over time. It includes an AI assistant powered by large language models for tasks like transcription, outline generation, and grammar correction, plus end-to-end encryption for privacy.
