SUBSTØR, a Molecular Substitution OS

Field notes

The page describes a four-stage process that begins with an ingredient, molecular structure, or SMILES representation and ends with ranked alternatives carrying scores and rationales. Its examples span cosmetic retinol and bakuchiol, polymer substitutions, battery-related materials, and steel grades. The public demonstration is explicitly illustrative: candidates and scores are pre-computed, while real projects are said to run on users' own structures. A visible implementation note leaves the current scope of regulatory-framework coverage unresolved.
