AI Protein Structure Viewer From the Protein Data Bank, free
Free. Use your own Anthropic or OpenAI key.
Also from Innerscene: Circadian Lab, a free lighting calculator for room illuminance, melanopic EML, and glare.
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
- No PDB ID is needed: the AI searches by description, compares the entries it finds by title, method and resolution, and names the one it loads.
- Chains are drawn as a cartoon, each in its own colour, with helices and strands, and bound ligands, cofactors and ions as ball and stick.
- DNA and RNA show as a tube along the backbone with the bases as sticks, and a space-filling layer is one click away.
Prompts to try
Click one to open it in the AI panel, then change the sizes to suit.
Getting the protein out
- Download the mmCIF from the version list in the AI panel, or note the PDB ID to fetch the entry elsewhere.
- For a render, AR or a 3D print, open the Export menu and choose GLB, USDZ, STL or another format.
- Save a PNG of the view, or a self-contained HTML page that opens the protein in 3D in any browser.
The mmCIF is the entry as published in the Protein Data Bank. The 3D exports are meshes of the cartoon and ligands as drawn, so a printed protein usually needs supports.
Best export formats: GLB, USDZ, STL, HTML

Good to know
Only structures that have been solved and published in the Protein Data Bank can be shown. The tool does no structure prediction, so a protein with no experimental structure cannot be made.
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.
