MolView – SMILES Preview is a Visual Studio Code extension that renders SMILES (Simplified Molecular Input Line Entry System) strings as molecular structure diagrams on hover. This means that you don’t have to copy-paste structures into a chemical drawing package to check them.
Powered by RDKit.js – the industry-standard chemistry toolkit for professional-quality molecular visualizations.
More details are here
- The extension uses pattern matching to detect SMILES strings
- Invalid SMILES are silently ignored (no error messages)
- Text abbreviations in reaction SMILES are not supported
- Large molecules (>100 atoms) may render slowly on first load
