Two offers, nothing else: the CovaSyn licence for your team (3-month pilot, then 6 or 12 months, cloud or self-hosted) and publicly bookable workshops whose price is 100 percent creditable towards a later contract.
14 to 41 percent without CovaSyn, 76 to 92 percent with CovaSyn. Measured on MolecularIQ, a benchmark we did not design (ICLR 2026, Klambauer Lab, Institut fuer Machine Learning, JKU Linz).

Deeper analysis
Independent benchmark · ICLR 2026
AI alone scores 14 to 41 % on chemistry. With CovaSyn: 76 to 92 %. Measured on the independent, peer-reviewed MolecularIQ benchmark (ICLR 2026) that we did not design.
Full benchmark data
Sound familiar?
„I just want to know what my compound is, and I'm stuck on spectra interpretation for hours."
CovaSyn interprets NMR, MS, IR & UV/Vis automatically: identity, purity, impurities.
The interpretation you know from Mestrenova, without needing Mestrenova.
„My stability package is due and the shelf-life calc drags on for days."
Arrhenius fit, shelf-life estimate, OOS/OOT flag: a solid first pass in minutes that your analytics lead signs off.
ICH-oriented, without an external statistics contract.
„I need a synthesis route, and I'm digging through SciFinder and Reaxys."
CovaSyn proposes retrosynthesis routes right on the molecule you drew.
The route search you'd otherwise open SciFinder or Reaxys for.
„A mutagenic impurity in the process, and the (Q)SAR assessment takes weeks."
ICH-M7-oriented screening, structural alerts, Tox21 in minutes, as a precursor to your final assessment.
A first risk picture instantly, instead of waiting for weeks.
One platform
Draw like in ChemDraw or ACD. Interpret spectra like in Mestrenova. Plan synthesis without SciFinder or Reaxys. Stability, tox, formulation, properties: all on the same molecule, in the same window, in seconds.
