Is the Seedream prompt builder free?

Yes. It runs in your browser, needs no account and keeps your recent prompts only on your device.

Does it generate images?

No. It writes the prompt. Paste it into any app that offers Seedream 5 Pro — or another image model — to generate the picture.

Why does it add whole sentences instead of keywords?

Seedream reads natural language, so a clear sentence per idea (light, lens, palette) gives it more to work with than a list of tags.
