An example structure
A sample file from the viewer, from the same sources the AI uses: PubChem, the Protein Data Bank, the Crystallography Open Database or a textbook lattice.
Watch how it works
How it works
- 1. Describe it or add a photoType what you want in plain words, with sizes if you know them, or add a photo as a reference. Describe an object or a person.
- 2. The AI builds and checks itThe AI writes an OpenSCAD program for an object, or sets up the character generator for a person. It looks at six rendered views of the result and fixes what is wrong, up to five builds per message.
- 3. Refine and exportThe model opens in the viewer at real size. Ask for changes in the chat, move the sliders, then download it or pick a format from the Export menu.
Why make it with AI here
- Common, IUPAC, drug and trade names all work, because known compounds are looked up in PubChem.
- Modified and new molecules, specific isomers and charge states are built from SMILES and checked for formula, R/S and E/Z labels, strain and atom clashes.
- The AI compares a 2D drawing of each result with your request and corrects the structure if it does not match.
Prompts to try
Click one to open it in the AI panel, then change the sizes to suit.
Getting the molecule out
- Download the SDF from the version list in the AI panel; a molecule built from SMILES keeps its SMILES in the file.
- Open the SDF in Avogadro, PyMOL, ChimeraX or another chemistry program.
- For a 3D model, open the Export menu and choose GLB, STL, OBJ or USDZ, or save a PNG of the view.
A molecule built from SMILES is a computed model: the lowest-energy conformer the tool found, which can differ from the shape in a crystal or bound to a protein. PubChem's 3D conformers are computed models as well.
Best export formats: GLB, STL, OBJ, PNG

Good to know
Small molecules only, up to about 600 atoms with hydrogens. Metal complexes cannot be built from SMILES; ask for them as crystals, which come from the Crystallography Open Database.
Cost and privacy
You use your own Anthropic or OpenAI API key. It is stored only in your browser and sent only to that provider, which bills you directly: a model typically costs $0.05 to $0.30 at Standard quality and up to about $1 at Detailed, and Innerscene charges nothing. Your key and prompts are not sent to Innerscene; we record anonymous usage statistics such as the steps used, the model chosen, token counts, a cost estimate and whether a model was made.
