Your Gemini API key

Bring your own key. It is not bundled with CBT Realm and this app does not save it. Your browser sends it directly to Google when you check the connection or analyse a PDF. Restrict the key to the Gemini API and this website's domain. Gemini usage limits or charges depend on your Google account; get a parent or guardian's help before enabling billing. Avoid entering the key on a shared or public computer.
