Is the CTR score calculated with a real AI model?

No. This score is a simple canvas heuristic that measures the brightness/saturation/edge contrast of the generated image — it is NOT a prediction model trained on millions of real YouTube performance data; it is intended for expectation management.

Are the variants (A/B/C) generated with different strategies (face-focused/text-focused/product-focused)?

No, all variants are generated from the same prompt; the only difference is the "Variation N." phrase added at the end.

Is there an expandable text/color/logo editor after generation?

No, brand color/logo can only be adjusted BEFORE generation; there is no post-generation interactive editor.

Can I download in both JPG and PNG?

No, the output is only in JPG format.

Is there a paid plan or daily quota?

No, the page is marked as "Quota: Test version — free unlimited use"; there is no Pro/paid tier or bulk generation mode.
