Sign up (it's free — no credit card needed). You get 5 free covers. Click "New Cover" in your dashboard, enter your book details and trim size, type a prompt describing the look you want, then click Generate. Your full-wrap PDF is ready in under 60 seconds.

A full-wrap cover includes the front cover, spine, and back cover as one continuous print-ready image — exactly what KDP requires for paperback upload. All three panels are calculated from your trim size and page count automatically.

All major Amazon KDP trim sizes: 5×8, 5.5×8.5, 6×9, 6.14×9.21, 7×10, 8×10, 8.5×11 — for both paperback and hardcover. We calculate spine width automatically based on your page count and paper type.

None at all. Just type a description of what you want (e.g. "dark psychological thriller, red smoke, abandoned city"). The AI handles the design, typography, layout, and dimension math.

Yes. When viewing a cover in History, click "Regenerate" to open the generator pre-filled with all your original settings. Change only what you want (e.g. swap the font style or change the background color in the prompt) and generate again. The rest stays the same.

In your prompt, specify the color: e.g. "dark blue background with red smoke" or "midnight blue background, gold typography". You can also re-open the generator from History with your existing settings and adjust just the prompt.

Six styles are available: Bold Modern (Helvetica Bold), Classic Serif (Times Roman Bold), Elegant Italic (Times Roman Bold Italic), Serif Light (Times Roman Italic), Modern Slanted (Helvetica Bold Oblique), and Typewriter (Courier Bold). Select one in Step 2 of the generator.

Yes. In Step 2 of the generator, there is a "Review Quote" field. Enter the quote text and the attribution (reviewer name / publication). It appears in gold italic on the back cover.

Yes. Enter your ISBN-13 in Step 2 and the barcode is generated and placed in the KDP-required position on the back cover. KDP also adds its own barcode if you leave the space blank, so this is optional.

AI image generation is probabilistic — the same prompt can produce different results each time. If you're not happy with the image, regenerate with a more specific prompt (add colors, mood, specific objects). Our prompt enhancer automatically improves your description before sending it to the image model.

Our engine uses Amazon's exact published formulas for dimensions, spine width, and bleed. Every export is validated before download. The vast majority of users upload successfully on the first try.
