Some people think in sentences. Others think in boxes, arrows, piles and pictures pinned to a wall. If that second group sounds like you, hello, friend! A blank document can feel like the wrong room to think in, and the right app hands you a canvas instead.
First, find your family
Most visual thinking apps belong to one of three families. Knowing which one you want saves a lot of trial and error (and a lot of half-finished boards in apps you forgot you downloaded).
- Open canvases put no rules on you. Drop things anywhere, connect them if you like, move them later. They're perfect for the messy, early "what even is this?" stage.
- Mind maps start from one central idea and branch outward. The structure does some of the thinking for you, which is lovely when your ideas have a natural hierarchy.
- Boards hold cards, images and notes you can rearrange. They suit research, reference gathering and mood boards, where the pieces come from lots of places.
No family is better than the others. Here's a quick way to tell which one is yours: picture a completely empty page. If it feels like freedom, you'll probably love an open canvas. If it feels like a wall, a mind map's central bubble gives you somewhere to start. And if your first instinct is to go and collect things, you're a board person.
Open canvases: room to spread out
Freeform
Apple's Freeform comes with your Mac, so it's the easiest place to start. A board is an endless canvas for sticky notes, text, shapes, lines and arrows, diagrams, tables, images, PDFs, links and freehand sketches. Boards sync through iCloud and can be shared with other people to work on together.
Perfect for: anyone who wants to try visual thinking without installing a thing, and anyone planning with friends, family or teammates who also use Apple devices.
Favorite feature: scenes. When a board gets big, a scene saves a view of one area so you can jump straight back to it, or step through them like slides. To make one, zoom and scroll until the area you want fills the screen, click the Scene Navigator button, choose Show Scenes, then click Add Scene. When you're ready to share, File > Export Scenes as PDF turns your scenes into a tidy little document.
Getting-started tip: you don't have to build everything inside Freeform. Drag a file onto your board straight from the Finder or another app, and it joins the rest of your thinking.
Scapple
Scapple comes from Literature & Latte, the makers of Scrivener, and it's the least fussy tool here. Double-click anywhere to write a note. Drag one note onto another to connect them. There's no central topic and no hierarchy to respect, which makes it ideal for the early, messy stage of an idea.
Perfect for: writers, planners and anyone whose brainstorms look like a scatter of words and phrases. Writers can drag notes straight into Scrivener when the thinking turns into drafting.
Getting-started tip: once your notes pile up, stack related ones into columns and add background shapes behind them to group them. Suddenly your scatter has neighborhoods! When you're happy with it, you can export or print the whole thing. Scapple runs on Mac and Windows, and there's a free trial for both.
Mind maps: when ideas branch
Xmind
Xmind is a long-running mind mapping app with a native Mac version, plus web and mobile versions. Beyond the classic map, it can show the same ideas as a logic chart, timeline, fishbone diagram, org chart or tree table, which helps when a map outgrows its shape. ZEN mode hides everything except the map, and Pitch mode turns a finished map into a presentation.
Perfect for: people who think in branches and outlines, and anyone who needs to turn a brainstorm into a plan they can present.
Getting-started tip: learn two keys and you can map as fast as you think. Press Tab to add a subtopic and ↵ to add a sibling topic. That's it! Keep your hands on the keyboard for the first ten minutes and get everything out, then go back and rearrange. There's a free version if you want to find out whether branching suits you.
Boards for research and projects
Heptabase
Heptabase is built for learning and research. Notes are cards, and cards live on whiteboards where you arrange them in space and draw connections between them. The same card can sit on several whiteboards without being copied, so one idea can belong to more than one line of thinking. You can also highlight and annotate PDFs inside the app, right next to your notes.
Perfect for: students, researchers and happy deep-divers who read a lot and want their understanding to build up over time instead of scattering across folders.
Good to know: Heptabase also has daily journals, a web clipper for saving pages as you browse, and integrations with Readwise and Zotero, so the highlights and sources you already collect can flow in. A friendly first project: one whiteboard for one question you're curious about, and a card for each thing you learn.
Curio
Curio is a Mac-only notebook organized around idea spaces: freeform pages where mind maps, lists, tables, index cards, pinboards, Kanban boards, images and PDFs sit side by side. Projects are local files on your Mac rather than pages in someone else's cloud.
Perfect for: people who want the whole project, from first sketch to task list, in one place.
Getting-started tip: use the Organizer's sections to give each phase of a project its own idea space (research, sketches, to-dos), then lean on tags, dates and priorities to keep track of what's next. The free edition covers five idea spaces, which is plenty for a first real project.
Mood boards: thinking in images
Milanote
Milanote is made for creative projects. Drag in images, notes, links, color swatches, videos and files, then arrange them into boards. You can invite people to edit, comment or just view, which makes it a natural fit for client work. There's a Mac desktop app as well as web and mobile versions, so you can catch an idea on your phone and place it on a board later.
Perfect for: designers, filmmakers, stylists and anyone who pitches ideas visually.
Getting-started tip: skip the blank board and start from a template. Milanote has templates for mood boards, creative briefs, storyboards and brainstorming. Add its web clipper to your browser too, and you can save links or content from the web in a single click while you browse.
PureRef
PureRef does one job, and does it beautifully: it holds reference images. Drag them in from Finder or straight from the browser, then scale, arrange, align and add quick notes on a single board. It runs on Mac, Windows and Linux.
Perfect for: illustrators, painters, 3D artists and designers who work from references.
Favorite feature: set PureRef to always stay on top, and your references float above your design or drawing app while you work. Bonus trick: toggle desaturation to see your references in grayscale, which makes light and dark values much easier to judge.
Which one fits how you think
| If you... | Try | A great first board |
|---|---|---|
| Want something already on your Mac | Freeform | A weekend plan or a room layout |
| Brainstorm in scattered words and phrases | Scapple | Every idea for your next piece of writing |
| Think in branches and outlines | Xmind | A project broken into phases |
| Study, research or build up knowledge over time | Heptabase | One question, one card per source |
| Want a whole project in one local file | Curio | A small project, from sketch to task list |
| Collect images to share with a client | Milanote | A mood board for a new brief |
| Need references beside your design app | PureRef | A reference sheet for today's drawing |
Try it: a one-week visual thinking test
Visual tools are easy to collect and just as easy to abandon. Here's a gentle plan for finding the one that sticks:
- Day 1: pick one. Use the table above and choose a single app. Just one!
- Day 2: bring a real project. Practice boards don't teach you much. Use something you actually need to think through this week.
- Day 3: dump everything in. Notes, images, links, half-thoughts. Don't organize yet.
- Day 4: arrange. Now move things around. Group, connect, stack. This is where visual thinking really starts to click.
- Day 5: use it to decide something. A plan, a direction, a first draft. A good board helps you land somewhere.
- Days 6 and 7: check in. Did you open it without being reminded? Did it help? If yes, wonderful. If not, try a different family next week.
When a plain document still wins
We love a good canvas, but it isn't always the answer. If your thinking is already mostly linear (a step-by-step process, a long argument, an email), a regular document is often faster. Boards can also become a very pretty way to procrastinate: rearranging cards feels productive even when nothing is getting decided.
A handy rule of thumb: use a visual tool to figure things out, then move the result somewhere simple once you know what you think. The board did its job, and it's still there whenever you want to go back.
One practical note: thinking visually tends to mean a lot of open windows. The board, the brief, a few browser windows of references and the file you're actually making. If finding the right one starts to break your concentration, Canopy CMD shows every window from the apps in its roster, including browsers, Figma, Obsidian and Finder, as a live preview while you hold ⌥ Tab. This one is ours.
Quick answers
Which of these can I try for free?
Freeform comes with your Mac. Xmind has a free version, Curio has a free edition that covers five idea spaces, and Scapple has a free trial on Mac and Windows.
Is a mind map or an open canvas better for brainstorming?
Neither wins every time. If a blank page sparks ideas for you, start with a canvas like Freeform or Scapple. If you need a starting point, a mind map's central topic gives you one.
Can I use more than one?
Of course! A thinking tool and a reference tool pair nicely, like Scapple for words and PureRef for pictures. Just add the second one after the first has earned its spot.
