Not an art tool — a math & assembly tool. Bring your art; we compute the spine, build the exact full-wrap canvas, and export a print-ready PDF.
Rendered as crisp text by the app on a scrim banner in the upper third — never baked into the AI art (image models misspell). Leave blank to ship art-only.
Copy-paste into Gemini / Ideogram. Sized to the exact pixels you need at 300 DPI.
Design a print-ready book cover, portrait orientation, 49:74 aspect ratio. Render at exactly 1838 x 2775 px (300 DPI, full-bleed — art runs to all edges). Subject and style: [describe your niche here]. CRITICAL LAYOUT: keep the TOP THIRD of the cover a calm, low-detail zone (even tone, no busy focal points) so the title and author can be overlaid on it legibly. The app renders the title text itself — do NOT render any text, letters, words, or logos in the image. Use high-contrast, print-friendly colors that hold up in CMYK. No watermarks, no borders.
Design a print-ready full-wrap paperback cover (back cover, spine, and front cover as one continuous image), landscape orientation, 1252:925 aspect ratio. Render at exactly 3756 x 2775 px (300 DPI, full-bleed). Subject and style: [describe your niche here]. COMPOSITION: the front cover is the RIGHT third; the back cover is the LEFT third; the spine is a thin vertical strip about 50% across. Keep the spine strip simple (solid or subtle texture). Keep the lower-right of the back cover clear for a barcode. CRITICAL: keep the TOP THIRD of the FRONT (right) panel a calm, low-detail zone for the title and author overlay. The app renders the title text itself — do NOT render any text, letters, words, or logos. High-contrast, CMYK-safe colors. No watermarks, no borders.
