Software for concept mapping#

You can draw every map in this course with a pen and a sheet of paper, and for thinking that’s often the best tool there is. The act of laying concepts out and naming the links between them is what does the learning — not the neatness of the finished picture. Software earns its place later: once a map grows past a page, when you want to rearrange it without redrawing the whole thing, or when you want to build and share it with other people.

The good news is that you don’t need anything specialised. Most general-purpose drawing and whiteboard apps handle the map types in this course perfectly well. The best tool is the one you’ll actually open, so pick from the options below and don’t agonise over it.

General visual canvases#

Best for the free-form maps in this course — spider, network, flowchart, fishbone, pictorial and mandala maps.

• Excalidraw — free and open-source, with a relaxed hand-drawn look. No account needed; good for quick maps you sketch and throw away.
• Miro and Whimsical — collaborative online whiteboards with generous free tiers and ready-made mind-map and flowchart templates. Reach for these when you want to build a map with other people.
• Obsidian Canvas — a free-form canvas built into a notes app, so your maps can link straight to your own notes and references.
• draw.io (diagrams.net) — free, no sign-up, and strong on structured diagrams and flowcharts; saves to your own drive or cloud.

Outline-driven mind maps#

If you want the classic Buzan-style radial mind map generated for you, these let you type a hierarchy and turn it into a map:

• XMind, Mindomo and Coggle — handy for note-taking and quick study maps where the structure is mostly a tree.

Formal concept maps with labelled links#

For the academic concept map proper — the Novak/Ausubel style where every connection carries a linking phrase (“causes”, “is a kind of”, “depends on”) — CmapTools, from the Institute for Human and Machine Cognition (cmap.ihmc.us ), is still free and purpose-built for exactly this. It’s the right pick when the relationships matter as much as the concepts themselves, which is common in study, teaching and assessment.

Prefer to type rather than draw?#

A whole family of tools turns plain text into diagrams — you write the structure as a few lines of markup and the tool draws it for you. Because the source is text, these maps live happily in version control: you can diff them, review changes, and regenerate the picture in seconds after an edit, instead of nudging boxes around by hand.

• Mermaid turns plain text into flowcharts and tree diagrams and is built into many Markdown editors and note apps, so a map can sit right inside the note it belongs to.
• PlantUML does the same for a wider range of diagrams — mind maps, work-breakdown trees, activity flowcharts and more — from a compact text syntax, rendered to clean SVG.

There’s one further trick worth knowing. A PlantUML activity diagram of a decision flowchart isn’t only a picture of how a decision is made — it can be compiled into executable logic. The clearlogic tool takes such a flowchart and turns it into a deterministic classifier you can actually run, so the same diagram you drew to understand a process can also enact it.

A note on AI-assisted mapping: large language models can now draft or restructure a map from your raw notes, which can save time getting a first version onto the page. Treat that as an enabling capability, not a proven learning gain — the benefit of mapping comes from you doing the selecting, organizing and connecting, so always check an AI’s draft against the source and, better still, rebuild it from memory yourself.

Which should you use?#

Don’t overthink it. A quick rule of thumb:

• Pen and paper first, for thinking a topic through.
• Excalidraw or draw.io for a fast digital map you’ll keep.
• Miro or Whimsical when you’re mapping with other people.
• CmapTools when the labelled links carry the meaning.
• Mermaid or PlantUML when you’d rather write than draw, or want maps you can keep in version control.

Exercise#

Pick one tool above and rebuild a map you drew earlier in this course. Pay attention to what the software makes easier — moving concepts around, re-linking, sharing — and what it makes slower, like the friction of an unfamiliar interface compared with a pen. Keep whichever genuinely fits the way you work, and don’t be afraid to go back to paper when you’re just thinking.
