Curio vs. Obsidian

Two local-first thinking tools that keep your work on your own machine — but built very differently. Curio is a native Mac notebook with a freeform visual canvas at its core. Obsidian is a Markdown vault you extend with plugins. 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 Obsidian?

Obsidian is a knowledge base that works on top of a local folder of plain-text Markdown files. It’s known for bidirectional links, a graph view, and a huge community-plugin ecosystem you assemble into your own workflow. It runs on Windows, Mac, Linux, and mobile.

Choose Curio if…

  • You want a freeform canvas as the core experience — not a Canvas view bolted onto a text editor.
  • You want rich text with real formatting as a first-class option, not Markdown only.
  • You want bi-directional links that carry meaning — wikilinks and backlinks plus typed references like Evidence and Rebuttal that capture why notes are connected.
  • You want mind maps, kanban boards, tables, and images together as figures on one canvas, without hunting for plugins.
  • You manage real projects: tasks with dates, checklists, statuses, and a built-in Organizer to see it all.
  • You’d rather have a polished native Mac app out of the box than tinker to assemble a setup.
  • You want a CLI and MCP support, so AI agents can work alongside you.

Choose Obsidian if…

  • You want a plain-text Markdown vault that stays readable in any editor, forever.
  • You rely on a huge community-plugin ecosystem to shape the app around your workflow.
  • You want the graph view to navigate a large web of interlinked notes.
  • You need Windows, Linux, or mobile — not just a Mac.
  • You enjoy tinkering and building your own setup from parts.
  • You want a tool that’s free to use, paying only for add-ons like sync if you need them.
