> Free guest chemistry learning in Tamil and English from Edunivra Private Limited, under Kalviyogi and 369 Tesla. The public student release has no account or subscription requirement.

Canonical origin: https://neetiitlab.com/chemistry/lab/
The student app includes guided lessons, virtual experiments, an educational workbench, atoms/molecules/crystal models and all 118 element profiles. Some activities use diagrams and numerical models; supported workspaces use 3D graphics. Scientific and Tamil content review remain pending. It is not an official examination-board resource, a complete syllabus guarantee, or an instruction to conduct chemical experiments without supervision.
