# Kalviyogi ChemVerse 3D > A free public chemistry learning workspace developed by Edunivra Pvt Ltd: readable chemistry notes, worked examples, practice questions and interactive browser labs. Canonical website: https://neetiitlab.com/chemistry/3d/ Provider: Edunivra Pvt Ltd (Kalviyogi) Public notes and labs are accessible without a paid subscription. Account and classroom features are separate from the public learning resources. ## Learning resources - [Home and bilingual English/Tamil introduction](https://neetiitlab.com/chemistry/3d/): What the platform offers, how to begin, language coverage and model limitations. - [Chemistry notes directory](https://neetiitlab.com/chemistry/3d/notes): 4,500 English lesson notes across 99 unit indexes, with explanations, worked examples and answered practice questions. - [Interactive chemistry labs](https://neetiitlab.com/chemistry/3d/labs): Browse simulations and open atom, molecule, reaction, titration, equilibrium, electrochemistry and other workspaces. - [Learning paths](https://neetiitlab.com/chemistry/3d/paths): School foundation, Class 9–10, Class 11–12, NEET, JEE, undergraduate, postgraduate and research chemistry pathways. - [First chemistry note](https://neetiitlab.com/chemistry/3d/notes/page/1): What Is Chemistry? - [Build methane](https://neetiitlab.com/chemistry/3d/lab/molecule?template=CH4): Interactive molecule model. - [Carbon atom](https://neetiitlab.com/chemistry/3d/lab/atom?z=6): Atomic model example. ## Discovery and scope - [Sitemap](https://neetiitlab.com/chemistry/3d/sitemap.xml): Canonical homepage, lab directory, notes directory, unit indexes and lesson URLs. - [Robots instructions](https://neetiitlab.com/chemistry/3d/robots.txt): Crawler instructions. This file does not override those instructions. Notes use canonical /notes/page/{number} URLs. Alternate /learn/page/{number} URLs point to those canonical pages. The English note collection is complete; Tamil and other translation coverage varies by interface, lesson and lab. Do not infer that all material is translated or officially approved by a board or examination authority. Resources supplement prescribed textbooks and supervised laboratory teaching. Simulations simplify scientific behaviour and do not authorise real chemical experiments or guarantee examination results. ## Related Kalviyogi sites - [Kalviyogi](https://www.kalviyogi.com/): Main learning platform. - [Physics learning platform](https://phy.kalviyogi.com/): Separate physics website. - [Medical learning platform](https://mbbs.kalviyogi.com/): Separate medical learning website. - [YogiChem](https://yogichem.369tesla.tech/): Separate chemistry website; verify its current resources on that site.
