WaveSpeed AI Chemical Structure Drawer
Browser editor for drawing molecules, calculating properties, exporting images and structure files, and viewing 3D models.
Free. 21 of 65 checklist features confirmed.
Main canvas
Default drawings
Caffeine
Paclitaxel
Cholesterol in 3D
- Hosted build identifier comes from the page's Next.js payload.
- Default canvas uses a dark background and element colors.
- Paclitaxel shows R/S labels on canvas, omitted from default SVG.
- Cholesterol SMILES-to-3D remained pending before SDF fallback.
- Default 3D view uses ball-and-stick, colored by element.
