Pauling runs docking, MD, ADMET, and binding-energy validation on cloud infrastructure through natural language -- no installation, no per-seat licenses, scaling to millions of compounds. Cresset Flare is a modern comp chem suite with strong FEP and lead-optimization tools, but it's per-seat licensed desktop software with no native cloud scaling.
| Category | Pauling | Cresset Flare |
|---|---|---|
| Free energy perturbation | Not yet available | FEP -- well-validated for lead optimization congeneric series |
| Docking | UniDock (GPU-accelerated Vina) -- scales to 10M+ compounds | Lead Finder -- accurate but limited to desktop-scale throughput |
| Electrostatic surface modeling | Not available | Cresset field technology -- unique electrostatic/hydrophobic field comparisons |
| Interface | Conversational AI -- natural language | Desktop GUI -- modern and well-designed, but traditional |
| Cloud scaling | Auto-scales to hundreds of workers on Google Cloud Dataflow | Desktop-bound; no native cloud parallelization |
| Cost model | Pay-per-compute, no license fees | Per-seat licensing; Flare + modules priced separately |
| MD simulations | GROMACS with auto ligand parameterization (ACPYPE), checkpoint save/resume, MM-PBSA | Limited -- basic minimization; not a full MD platform |
| ADMET profiling | Integrated into every workflow | Not a core capability; relies on external tools |
| Lead optimization tools | Docking, MD, ADMET, binding energy validation as an integrated pipeline | Purpose-built for lead opt -- activity cliffs, SAR analysis, field-based alignment |
| Pocket detection | P2Rank (ML-based, automatic) | Active site detection available but less automated |
| File format handling | Automatic conversion (PDB, SDF, MOL2, SMILES, CIF, PDBQT) | Handles standard formats; some manual prep required |
| Structure validation | MolProbity + PoseBusters (automatic QC) | Visual inspection; no automated pose QC pipeline |
