Real Cheminformatics

Find a functional substitute for any ingredient

Banned ingredient? Expensive? Unavailable? The system analyses molecular structure and ranks substitutes with scientific reasoning — built on RDKit Tanimoto + Lipinski + molecular-weight balancing.

Ranked substitutes

Enter an ingredient on the left to see substitutes here.

How it works: The system converts your input to a Morgan ECFP4 molecular fingerprint, computes Tanimoto similarity against every ingredient in our database, then ranks substitutes by: structural similarity (60%) + molecular weight closeness (25%) + Lipinski match (15%). Each result comes with auto-generated scientific reasoning.
