Heptabase
Visual note-taking and knowledge management app with infinite whiteboards, AI chat, and a card-based system for deep research.
Heptabase is a knowledge management app designed around visual thinking. Unlike traditional linear note-taking apps, Heptabase organizes information as cards on infinite whiteboards, making it easy to see connections between ideas spatially. AI Chat lets users ask questions across their entire note library and get answers grounded in their own content. The tool supports PDF annotation, bi-directional linking, and a journal system, making it well-suited for researchers, students, and knowledge workers building a personal second brain. Heptabase has grown significantly since its 2022 launch, particularly in academic and research communities.
