Frequently asked questions

Is Physica free to use?

You can open and use the simulations and the tutor directly in your browser. If anything about access changes in future, it will be announced on this site.

Which classes and exams does it cover?

Class 11 and Class 12 Physics (all NCERT chapters) with simulations, and Chemistry, Botany and Zoology simulations. The AI Tutor is useful for school exams, Boards, JEE and NEET preparation.

How do I use the AI Tutor?

On the first page choose Student mode, open any simulation and switch on AI Tutor at the top. You can type or speak in English, Hinglish or Hindi, and choose the language from the 🌐 menu.

The tutor’s voice is not working or sounds robotic.

The voice comes from your own phone or browser. Turn up the volume and make sure the 🔊 button in the tutor is on. For the most natural voice, use Microsoft Edge or a recent Chrome; on phones, install a Hindi/English voice in your device’s text-to-speech settings.

The simulation is slow or blurry on a big smart board.

Press Focus on the simulation for a full-screen view. Physica automatically keeps motion smooth on large 4K boards. If it is still slow, tell us the board’s brand and model below.

Can I install Physica like an app?

Yes. Use the Install option on the first page, or your browser’s menu → “Install app” / “Add to Home screen”.

Do you store my name or chats?

The name you give the tutor, your stars and settings are saved only in your own browser. See our Privacy Policy for details.
