Curio vs. Heptabase

Both let you think visually on a canvas, but they’re built for different jobs. Heptabase is a card-and-whiteboard knowledge base for research and learning. Curio is a mature native Mac project notebook that also manages the work. Here’s the honest comparison.

What is Curio?

Curio is a native Mac notebook built around freeform idea spaces — canvases where notes, mind maps, lists, tables, kanban boards, images, and documents all live side by side. Your projects are files on your Mac, not pages in someone else’s cloud.

What is Heptabase?

Heptabase is a visual knowledge base built for research and learning. You capture ideas as Markdown cards and arrange them spatially on whiteboards, linking them into a connected web of knowledge with tags, backlinks, PDF annotation, and a journal. It runs on Mac, Windows, Linux, mobile, and the web, syncing through your account.

Choose Curio if…

  • You want a mature, native Mac app that’s been refined for over 25 years.
  • You need project management beyond thinking: tasks with dates, checklists, statuses, kanban boards, and a built-in Organizer.
  • You want your work in local files with no mandatory sync account — private, offline, and yours.
  • You want notes your way: rich text with real formatting and Markdown, both native.
  • You want links that carry meaning — wikilinks and backlinks plus typed references like Evidence and Rebuttal that capture why two notes are connected.
  • You want mind maps, lists, tables, and images as figures alongside your notes on one canvas.
  • You want a CLI and MCP support, so AI agents can work alongside you.

Choose Heptabase if…

  • You do deep research or learning and want a card-based visual knowledge base.
  • You want whiteboards that link directly into a connected web of notes with backlinks and tags.
  • You annotate PDFs and pull highlights out as cards.
  • You want a daily journal woven into your cards and whiteboards.
  • You need it on Windows, Linux, a tablet, or the web, with everything syncing across devices.
