JustJot.ai vs Heptabase

Visual thinking on a whiteboard — and an AI that reads every card you've placed.

Heptabase is a visual note-taking app built around a spatial whiteboard: drag cards onto a canvas, link them visually, and see how ideas connect in 2D. It is genuinely powerful for researchers and students building conceptual maps. JustJot.ai takes the same content-first philosophy and adds grounded AI chat with citations, deep-research reports, AI study artifacts, and a publishing surface — so the ideas you map on a canvas can reach an audience, go behind a paywall, or become a cited resource.

Frequently asked questions

Does Heptabase have an AI chat feature?

Heptabase ships an AI assistant that can summarise and answer questions about a whiteboard. It is not deeply grounded in your full library with source citations. JustJot.ai's grounded chat lets you select any source set — a single card, a whole space, or your entire library — and returns answers with inline citation chips linking back to the exact passage.

Can I publish my Heptabase whiteboards?

Heptabase does not offer public publishing or audience monetization. JustJot.ai makes every node a live SEO-indexed page, supports per-section paywalls, and builds an owned subscriber list — so the research you map in a whiteboard can become a published piece that generates revenue.

I love the Heptabase whiteboard. Does JustJot.ai have that?

JustJot.ai has a Spaces graph view for linked nodes but does not replicate Heptabase's spatial drag-and-drop whiteboard canvas. If the primary workflow is visual spatial mapping of ideas, Heptabase is the stronger choice for that specific surface. JustJot.ai is the better fit when grounded AI, citations, study artifacts, and publishing are also on the list.
