About and disclaimer

VEX Molecule Studio is an educational tool for exploring molecules, proteins and science equations in 3D. It is built for learning and teaching, not for laboratory, safety or professional use. It contains no AI features, though AI tools helped build it.

Last updated 22 October 2026

Who made it

Molecule Studio is made by Julian Neagu, a solo founder in London, for VisionVix. It is part of the VisionVix Simulators collection of interactive 3D tools.

AI disclosure

There is no AI inside Molecule Studio. No chatbot, no AI answers and no AI model runs when you use it. Every shape, value and equation comes from fixed rules and the data sources listed below, so the same molecule always gives the same result.

The Studio was built with the help of AI tools, which assisted with writing code, drafting text and checking content. Julian reviewed the result and ran a pre-launch audit: every control was tested in a browser, and the chemistry data, equations and protein labels were fact-checked against reference sources. AI-assisted work can still contain mistakes, which is one more reason to treat the Studio as a learning aid and check important values yourself.

Educational use

Everything in the Studio is a teaching model. The models make chemistry visible and easy to play with, so some detail is simplified on purpose. Use them to build intuition, then check exact values against your textbook, your teacher or the primary sources listed below.

What the models simplify

Shapes and angles come from VSEPR theory. The badge shows the predicted shape, for example "Bent, 104.5°" for water. Real molecules can differ by a few degrees.
Library molecules use idealised coordinates with typical bond lengths. They are not measured crystal or gas-phase structures.
One structure per molecule. Ozone and sulfur dioxide are drawn as a single Lewis structure. The real molecules are resonance hybrids, which the Studio notes in the Info panel.
Bonding rules follow a simple valence model. Sulfur may take up to 6 bonds and phosphorus up to 5. Ions, formal charges and metal coordination are not modelled in full.
Bond lengths and energies are average textbook values. The real value depends on the molecule.
Atom sizes and colours follow display conventions (covalent radii and CPK/Jmol colours), not true atomic sizes or the colours of the substances.
PubChem imports use PubChem's computed 3D conformers. One conformer is one possible shape, not the only one.
Equations and graphs show the standard textbook form of each law. Conditions are stated on each card, and graphs use scaled units (for example x stands for r or t).

Not for practical use. Don't use the Studio to plan experiments, mix or handle chemicals, work out doses or make safety, medical or engineering decisions. For any real substance, follow its Safety Data Sheet and your lab's rules. The Studio is provided as is, without warranty. Results may contain errors.
