Deterministic engines calculate. AI explains only the signed result.
Deterministic engines, validated against NIST and IUPAC standards.
All 118 elements with NIST-validated atomic weights, electron configurations, and spectral data.
pH, stoichiometry, gas laws, thermodynamics, molarity, and more with step-by-step solutions.
Interactive 3D visualization with CPK coloring, rotation controls, and VSEPR geometry.
Drag-and-drop atoms with real-time stability validation and 3D preview.
22 functional groups, 40 named reactions with mechanisms, and reaction predictor.
IR interpreter, NMR analyzer (¹H & ¹³C), and mass spectrometry tools.
Balance chemical equations with systematic matrix reduction and verification.
Generate Lewis dot structures with formal charge analysis and resonance forms.
Explore the full workbench: nuclear chemistry, lab safety, electron configuration, and more.
AI can hallucinate. VerChem signs every answer so you can audit the chain of trust.
Every number is produced by a deterministic algorithm — no stochastic LLM sampling. The same input always yields the same output.
Each result is sealed with an HMAC-SHA256 signature bound to the calculation inputs, engine version, and timestamp. Tamper-evident by design.
AI only narrates around the signed numbers — it never generates the result itself. If the explanation drifts, the signature still validates the math.
