Figviz

Hi Fazier! We built Figviz because making a clean, labeled science diagram usually means an hour in a generic drawing tool. With Figviz you describe a concept (or drop in a PDF) and get an accurate, labeled figure in seconds — biology, chemistry, physics, and K-12 math — ready to export as a print-ready PNG for worksheets, slides, or papers. There are also 150+ free diagram tools, interactive concept pages, and a simple API. Free to start with 3 credits, no subscription. We'd love feedback from teachers and students!

Science education workflow friction removed. Teachers spend hours creating accurate cell diagrams, reaction mechanisms, lab setups - all outside their area of focus. Non-art educators stuck either hiring graphics help or settling for rough sketches that confuse students. Figviz eliminates that expertise barrier. Students can now generate accurate figures for reports and presentations instead of copying images from textbooks. Free tier removes adoption friction for classrooms with tight budgets.

figviz has great potential and offers some useful features, but I encountered a few issues that could be improved. Please contact me so I can share detailed feedback and suggest the changes I'd like to see. WhatsApp: https://wa.me/447307349530 Telegram: t.me/rforrank

This looks really useful for education. Clean, accurate diagrams take a lot of time to create. I'd be interested to see how well it handles more complex biology or chemistry diagrams from longer PDFs.

Turning a PDF into a labeled STEM diagram could save teachers a lot of prep time, especially for worksheets. How do you validate scientific accuracy on more complex reaction mechanisms or free-body diagrams before export?

Turning a PDF into a labeled STEM diagram could save substantial preparation time. It would be especially useful if each generated label could link back to the source page or passage in the PDF. How do you validate scientific accuracy for complex reaction mechanisms and free-body diagrams before export?

Impressive scope for teachers. The hard part with AI diagrams is confidently wrong output (a mislabeled reaction mechanism is worse than no diagram), so I am curious how you handle verification before a teacher prints it. Also, is SVG export planned? Print-ready worksheets often need vector rather than PNG.

The accuracy angle matters more here than in any other AI image niche. A wrong label on a cell diagram is worse than no diagram, because a teacher will print it and 30 kids will learn it wrong. How do you verify correctness on the science side, is there a review layer or curated templates behind the generation? Also the developer API is a nice surprise, generating labeled free-body diagrams from text could be great for physics content pipelines. The pay-as-you-go pricing without subscription fits how teachers actually buy things.

The pay-as-you-go model fits teachers better than another subscription. One workflow I’d love to see is a reusable class style/template: lock terminology, label density, colors, and difficulty level, then generate a consistent set of diagrams for a whole unit. Does the current API support those constraints, or is each output styled independently?

Would love to know which AI model you guys use for it?

I think it’s absolutely crucial that this diagram is free.

Science education workflow solved. Most STEM teachers spend hours hunting for accurate, labeled diagrams or drawing them manually - and getting the cell anatomy or chemical notation exactly right takes multiple passes. Figviz eliminates that entire research and illustration phase. Just describe what you need and get print-ready diagrams in seconds. The API angle is clever too - edtech teams building course platforms can finally offer dynamic visual generation instead of licensing static image libraries. For homeschooling parents trying to teach complex concepts, this removes the barrier of not being able to draw. Real win for making science teaching less about diagram management and more about actual learning.
