Developing Classroom Images in Napkin
Napkin is an AI-powered visualisation tool that turns text into clear diagrams, flowcharts, mind maps, and infographics. It helps teachers, students, and professionals communicate ideas more effectively without needing graphic design skills. Users simply enter text, and Napkin automatically creates editable visuals that can be customised and shared for presentations, lessons, or reports.
Here are 5 rules for teachers starting with Napkin - to save you time and avoid the "another tech tool" trap:
- Don't start from scratch. Start from what you already teach.
Don't type prompts. Paste in what you have - your lesson notes, a definition, a paragraph from a worksheet, an exam question, student feedback. Napkin is best when it turns your existing text into a visual, not when you try to make it generate content. - Use it to make thinking visible, not just pretty.
The best use isn't decoration. It's clarification.
- A process becomes a flowchart
- A comparison becomes a Venn / matrix
- Causes/effects become arrows
- A hierarchy becomes a pyramid
Ask before you generate: "What do I want students to understand faster here?"
- Pick one visual style and stick to it.
New teachers get lost in colours and icons. Choose 1 clean style (I tell teachers: simple line, monochrome) and use it for a whole topic / term. It saves time, looks professional, and students stop noticing the design and start noticing the learning. You can always edit the icons later. - Export wrong on purpose, then fix it live.
Napkin will get it 80% right. That's perfect for class. Put the visual on the board and ask: "What's missing? What's wrong here?" Let students correct it. It turns a static diagram into a discussion and stops you spending 20 minutes perfecting it. - Build a bank, don't make one-offs.
Create a folder called "Napkin - [Your Subject]". Every time you make something useful - revision summary, process for essay writing, career pathway, classroom routine - save the PNG + the share link. In 4 weeks, you'll have 20+ visuals you can reuse for slides, handouts, Teams/Classroom posts, and revision booklets.
Starter challenge: Take one topic you teach next week that students always get confused by. Paste your 150-word explanation into Napkin and generate 2 different visuals. Use one as your starter, one as your plenary.
