Reviewers mostly praise Heptabase for visual thinking: they use it to map ideas, study, research, brainstorm, write, and organize knowledge in a way that feels intuitive and helps connect concepts. Several say it stands out from tools like Notion, Obsidian, Roam, and Logseq because it needs less setup and better supports complex thought. Regular updates and a responsive team also come up often. The main reservations are friction in daily use, rough UI/UX, weak to-do handling for some workflows, and notably mixed reports on performance, especially on large whiteboards.
