I first mentioned this utility back in March and I’ve been using it since then and I have to say I find it invaluable.
Clipboard-to-SMILES-Converter is a lightweight macOS app designed to simplify the conversion process between a variety of chemical notations for chemical structures, such as Images of Molecules, SMILES, SELFIES, RdKit Mols, InChI, CAS numbers, and IUPAC directly in the clipboard.
