Connect your AI

Use your own Grok, ChatGPT, Claude or Gemini. Your questions go from this browser straight to your AI and back. TheoreticalPhysics.ai never sees them, and your key stays in this browser.

The easy way: the AI you already have

Keep talking to your AI on its own site (ChatGPT, Grok, Claude or Gemini, free or paid). The free AI Record add-on for Chrome writes every question and answer into your AI Record, word for word. No key and no other bill.

Optional: ask from this page with a key

What is a key, and what does it cost?

A key lets this page talk to your AI for you. You make it on the AI company’s own site with “Get a key”, then paste it here once. Each company charges for its use directly to you, usually a few cents per question; TheoreticalPhysics.ai charges nothing for it. A monthly chat plan such as ChatGPT Plus or SuperGrok is separate from a key; if that is what you have, you do not need a key: use the add-on above. A key is an extra, never required. Under 18? Ask a parent or your school; AI companies have age rules for keys.
