ConceptViz
ConceptViz is narrowly built for one job: turning a text description into a correctly labeled science figure, which is faster than dragging shapes in a general diagramming tool when the content is technical. It has moved upmarket since launch: the entry plan is now about $250 a year, document-driven figure sets need Pro, and the API sits on the $1,500-a-year Max plan.
Pros
- Exports to editable SVG, not just a flat image
- Free start lets you try it without a card
- Agent refines a figure over conversation and, on Pro, plans sets of related figures from your documents
Cons
- Free start is only 2 image credits valid for 7 days
- Scope is specifically science figures, not general-purpose drawing
- API access is reserved for the most expensive Max plan
- SVG and PPTX exports cost extra credits on top of generation
