before you ask.we already answered.
Six honest answers to the questions chemists send first.
Yes. Prompts and structures are encrypted at rest, never used to train shared models, and exportable on demand. Delete everything from one screen, any time.
Every structure passes through RDKit for parsing and atom balance, OPSIN for name ↔ structure round-trip, and Semantic Scholar for citation checks. Anything that fails is re-prompted, never shipped.
Anytime. Free stays free. Paid tiers cancel mid-cycle with no penalty. Your workflows and notebook stay accessible on Free after downgrade.
Generic LLMs hallucinate structures and invent papers. moll refuses to ship an answer that does not pass the critic gate. Same effort from you, very different floor.
Yes — JSON, CDXML, MOL, SDF, PDF, or a one-click ZIP. Your data, your hard drive. Even on Free.
Lab Plus generates Gaussian, ORCA, and Psi4 input files from any drawn structure with sensible defaults you can override.
