Show HN: ConceptViz – Generate STEM diagrams for teachers from simple prompts

1 points by zane0924 an hour ago

I built ConceptViz (https://conceptviz.app ) for teachers who spend too much time searching or drawing diagrams for science and math lessons.

You type a short description like “ray diagram for a convex lens”, “cell mitosis stages” or “series vs parallel circuit for grade 8”, and it generates clean, high-contrast, white-background diagrams that drop straight into slides, worksheets, or exams.

It’s focused on clarity and consistency rather than fancy “AI art”. You can pick an approximate grade level so the diagram is simpler or more detailed.

It’s free to try right now. I’d love feedback on:

topics where you struggle to find good diagrams

missing export options / features

any obviously wrong or confusing outputs

Happy to answer questions and hear suggestions in the comments.
