What do I need for AI drawings?
An OpenAI or Gemini API key in Settings (the same key Covers uses: OpenAI under Extra tools, Covers; Gemini under AI engines). Each page is one picture from that key, paid by your provider as usual. Without a key the panel says "Add an OpenAI or Gemini key in Settings (the one Covers uses) to draw these pages." Planning the page ideas also needs an AI engine.
