Mappy vs Obsidian Canvas: two ways to connect notes

The starting point changes the workflow

Mappy starts from connected nodes. Short labels form the structure, and expanded notes keep explanations and richer material attached to those ideas. Keyboard commands help you build branches before filling in every detail.

Obsidian Canvas is a core plugin for arranging notes, attachments, web pages, and text cards in a two-dimensional space. It can use notes from an existing vault, and saves canvases in the open JSON Canvas format.

My interpretation: a branching outline can be useful when you are building an argument from scratch; a freeform board can be useful when you are arranging material you already have. Your actual documents may favor either approach.

Be accurate about the price

Mappy is a one-time-purchase Mac app without a subscription. Obsidian's pricing page says the app is free to use, with optional paid services such as Sync and Publish. Avoid treating those optional services as a mandatory cost of using Canvas.

If a free tool already does the job, paying for Mappy needs a workflow reason, not a misleading comparison. The question is whether you prefer its connected-node editing and integrated expanded notes enough to choose it.

Try a small essay plan both ways

Take a question, three claims, two sources, and one counterargument. In a map, make claims the main branches and keep evidence below them. On a board, arrange the existing notes and sources, then connect what belongs together.

Ask which version helps you find a missing explanation. Can you tell what is evidence and what is your interpretation? Can you get from the overview to the longer writing without losing your place? These are more revealing tests than comparing how many empty cards fit on screen.

Mappy may suit someone who wants the map to be the primary document. An existing Obsidian user should weigh the benefit of staying with their current notes and established workflow.

Treat formats as a separate decision

Mappy uses .mindmap documents. Obsidian's Canvas format is different. Mappy does not claim to import .canvas files or entire Obsidian vaults. Keep the original material and test any proposed migration on copies.

If long-term interoperability is your priority, inspect the actual editable and exported formats, not just a screenshot. If getting started quickly on one personal Mac is the priority, test the capture flow. Choose for that priority openly rather than making one app win every category.
