Book Carousel Generator

4-slide square carousel · Flux header art + Gemini copy

Note on the Gemini connection: this file calls the Gemini API directly from your browser with your own key. It's built to run as a local file (or on your own host) — not inside Claude's chat preview, which blocks calls to outside APIs. Open it in a normal browser tab and it works as expected.

BFL.ai API key CORS proxy URL (optional)

Stored in this browser only. Get a key at dashboard.bfl.ai. If you see "Could not reach api.bfl.ai", set the same proxy URL you use in Prompt Studio.
