Heptabase

Linear note-taking tools weren't built for understanding complex topics — they were built for capturing words. Heptabase is different. It's a note-taking tool designed for visual learning and knowledge management, helping you actually make sense of complex subjects and research projects through whiteboards, mindmaps, tables, and kanban boards. It supports PDFs, audio, video, and journal formats all in one place, with real-time sync, offline access, and collaboration features for working with friends and teammates. When understanding is the goal, not just recording, Heptabase is the tool.
