Enter the title, pick a genre (literary fiction, thriller, romance, sci-fi, fantasy, self-help, business, memoir), set the mood (dramatic, mysterious, whimsical, bold), optionally describe the plot, and the AI generates a 2:3 portrait book cover via SDXL in under 15 seconds.
Yes — each cover costs ~1,000 tokens from your daily free pool (2,500 guest, 10,000 signed-up). No watermark on downloads. No subscription, no credit card, no trial limits.
Default output is 1024x1536 PNG (2:3 ratio). This upscales cleanly to Kindle 1600x2560, IngramSpark 6x9 inch 300 DPI, and most paperback trim sizes. For KDP-compliant PDFs, export through Canva, Affinity Publisher, or Book Brush.
Currently the generator produces the front cover only. Use the generated front art as the visual anchor, then extend the spine color and back blurb layout in Affinity Publisher, Canva, or KDP Cover Creator for the full dust jacket.
Yes. SDXL outputs are royalty-free with no attribution required. Upload as-is to KDP, Draft2Digital, IngramSpark, Smashwords, or any self-publishing platform. Upscale with /image/upscaler/ if you need more than 300 DPI for large-trim hardcovers.
Canva ($12.99/mo) and BookBrush ($9-24/mo) give you templates + clip-art libraries. Free.ai generates original artwork from SDXL per title — unique, not a template your rival also used. Combine: generate the art here, typeset the title in BookBrush if you need precise kerning.
Yes — the Genre chip primes SDXL with genre-native visual cues (dark grit for thrillers, painterly florals for romance, neon cityscapes for sci-fi). Pair with the Mood chip for fine-tuning. Self-help and business pick clean typography + minimal iconography.
SDXL can render short text at reasonable fidelity but is not a typesetter. For publishing-grade title typography, generate the art without forced text, then add your title in Affinity, Canva, or Adobe Express where you control kerning, tracking, and color.
Sci-fi, fantasy, thriller, romance, and horror have the strongest SDXL training priors — expect cinematic, high-impact results. Literary fiction and memoir need a tighter prompt — describe the mood + key imagery for best output. Try 3-5 variations per title.
Yes. Regenerate with the same inputs to get variations on the same style, or tweak the Mood or Genre chips for a fresh direction. Each regenerate costs ~1,000 tokens — the daily pool covers dozens of iterations.
Yes — covers you generate on Free.ai are yours to publish commercially, sell, print, and distribute without attribution. The SDXL model license (stability.ai/license) covers commercial use for individual authors and small publishers.
Yes — POST to /v1/image/generate/ with your prompt and tool=design-book-cover. Series authors, self-publishers, and indie presses use it to batch-produce consistent-style covers. Full Python, Node, cURL examples at /api/.
