Heptabase is the best place to think spatially about your notes; Pith is where your reading turns into a cited wiki you can hand to a client.
Heptabase is a visual note-taking tool: cards on infinite whiteboards, PDF annotations that become cards, mind maps, and bi-directional links, all offline-first with strong local data ownership. It is superb for deep, exploratory thinking you arrange by hand. Pith works differently — you bookmark what you read and it auto-builds a cited wiki and per-client briefings, every claim linked to a saved source, with an MCP server so AI assistants can query it. Heptabase is a canvas for your mind; Pith is an auto-built, source-grounded knowledge layer for client work.

When Pith wins
You need shareable, cited output
Pith turns your reading into a wiki and briefings where every claim links to its source, ready to hand to a client. Heptabase produces a personal visual canvas that is powerful for you but not a source-grounded deliverable.
You want AI to query your knowledge
Pith ships an MCP server, so assistants like Claude can search your reading memory and answer with citations. Heptabase has no MCP server for external assistants, so your cards stay inside the app.
EU data residency matters
Pith hosts data in Frankfurt, which is decisive for DACH consultancies and GDPR-sensitive clients. Heptabase syncs through its own servers and does not advertise EU-specific residency, and currently does not offer end-to-end encryption.
Where Heptabase wins
You think visually and want local-first ownership
Heptabase is genuinely best-in-class for spatial thinking — infinite whiteboards, mind maps, PDF-annotation-to-cards, and deep-research workflows. It is offline-first with daily local markdown/JSON backups and optional self-hosting, so if you value a visual canvas and strong local data ownership, Heptabase wins clearly.
FAQ
Is Pith a visual whiteboard like Heptabase?
No. Heptabase is built around infinite whiteboards and spatial card arrangement; Pith produces a structured, cited wiki. They suit different mental models — visual exploration versus source-grounded output.
Does Heptabase auto-build a wiki from my reading?
No. In Heptabase you create and arrange cards yourself, including turning PDF highlights into cards. Pith auto-assembles a wiki from what you bookmark, with each claim linked to a saved source.
Does Heptabase have an MCP server?
Not for external AI assistants. Heptabase focuses on its own visual app rather than exposing your data over MCP. Pith provides an MCP server so tools like Claude can query your reading memory and cite sources.
Where is my data stored?
Pith hosts in Frankfurt, in the EU, which matters for DACH and GDPR-sensitive teams. Heptabase syncs via its own servers with daily local backups, but does not advertise EU residency and currently lacks end-to-end encryption.
Which tool is better offline?
Heptabase is offline-first and local-first — you can fully read and edit without a connection, with daily local backups. Pith is a cloud SaaS, so Heptabase clearly wins for offline and local data ownership.
Can Heptabase produce per-client briefings?
Not as a built-in feature. You could build a whiteboard per client manually, but Pith auto-generates briefings per client with citations behind each point, which is a core Pith workflow.
How does pricing compare?
Heptabase is around $8.99/month billed annually, with a one-time lifetime plan near $659. Pith is a SaaS subscription priced around an auto-built, EU-hosted, source-grounded knowledge layer rather than a personal canvas.
Can I use both together?
Yes. Some people think visually in Heptabase and use Pith to turn their actual reading into a cited, shareable wiki and briefings. They overlap less than they complement — canvas for exploration, Pith for source-grounded deliverables.
