Heptabase is a visual thinking and note-taking tool that organizes knowledge on infinite whiteboards. Users create notes (cards) that can be arranged spatially on whiteboards, tagged, linked, and grouped to reflect how concepts relate to each other. AI features help search across cards, suggest connections, and synthesize information from multiple notes. Academic researchers, students, writers, and complex thinkers use Heptabase to map out the relationships between ideas visually. The spatial arrangement of cards on whiteboards allows for non-hierarchical organization that reflects conceptual proximity rather than folder structure. A researcher can have a whiteboard for each project with related cards clustered by theme. Heptabase is built by a team of researchers and academics and reflects deep thinking about how knowledge actually organizes in human minds. The tool is particularly popular in academic circles for literature review, thesis planning, and research synthesis. The whiteboard interface makes it easier to see the shape of a research area rather than just listing sources.

What the community says

Heptabase has earned a devoted following in academic and research communities, with users consistently describing the visual whiteboard organization as superior for complex research. Reddit's r/PKMS regularly recommends it for academic use cases. The main criticism is that it's primarily designed for organizing existing notes rather than capturing on the fly.
