ConceptViz

ConceptViz makes scientific diagrams for classrooms and research. It is an AI diagram generator for STEM education that turns a topic into a 4K image you can use in lessons, papers or posters.

The free plan gives you a one-time bonus of 3 diagram credits, covers all subjects and allows classroom use, but you generate one diagram at a time and history is kept for 7 days.

Free images are not cleared for commercial work.

Paid plans start with Standard at $10 a month for 80 credits, no watermark, a commercial use license, batch generation and a priority queue.

Pro costs $20 a month for 160 credits, bigger batches, 24-hour priority support, 90-day history and early access to new features.

There is also a limited-time $199 Lifetime Deal with all Pro features, 1,500 one-time credits, up to 5 diagrams at once and 180-day history.

Teachers who only need a handful of figures can stay on the free plan.

Anyone producing diagrams regularly will hit the credit limits quickly.
