MolTalk Demo — Molecular Drawing, 3D Visualization, Editing, and Validation in ChatGPT

This short demo shows MolTalk working inside ChatGPT as a chemistry-aware MCP plugin. The video demonstrates: drawing dodecahedrane from a natural-language request; rotating the structure in 3D and showing explicit hydrogens; modifying cyclohexane by adding an epoxide; handling an ambiguous stereochemical name by asking for clarification rather than guessing. MolTalk uses RDKit, OPSIN, and validated structure data to help AI assistants resolve, draw, inspect, modify, and export molecular structures while preserving chemical identity and stereochemistry.
