Setup & how it works

Get an API key at aistudio.google.com/apikey, paste it into Settings. It's kept only in this browser.
Pick a save folder (Chrome/Edge desktop). Point it at your Google Drive for Desktop folder (e.g. G:\My Drive\AI Images) and Drive uploads each image to the cloud automatically. On other browsers, choose "Download each image" instead.
Paste your numbered list and press Start. It generates each item in order, saves it, waits a randomized cooldown, and moves on. Progress is remembered — reload or come back later and it skips what's done.

Safety-blocked prompts and errors are logged and skipped so a long run never gets stuck. If you hit the daily quota it stops cleanly; run again later to resume.
