Heptabase, founded in 2021, organizes notes around a visual whiteboard rather than a linear document or folder structure, letting a user spatially arrange, connect, and cluster related ideas the way someone might physically arrange index cards on a table when working through a complex research project or literature review.
That whiteboard-first navigation suits work that's inherently non-linear: mapping how dozens of sources relate to each other, tracing an argument's structure across multiple documents, or planning a complex project where the relationships between pieces matter as much as the pieces themselves, rather than a basic chronological or hierarchical note structure.
There's no free tier; pricing starts around $9 a month. For a researcher, student, or anyone working through genuinely complex, interconnected material where spatial arrangement helps thinking, Heptabase's visual whiteboard approach to note connection is built specifically for that kind of work rather than simpler, linear note-taking.
