OpenSketch is a free diagram and figure editor for scientific workflows to use in papers, presentations and posters.
Here, you can combine scientific illustrations with editable shapes, labels and connectors, and export as formats such as SVG, PNG, PDF, PPTX and more.
The app currently comes with a set of ~1000 biomedical SVG assets (detailed & simplified illustration modes) following a coherent design theme, all created with GPT-6 Astra.
