Book covers · Movie posters · One studio

Covers that sell the story before page one.

CoverSlay is a cover creator that lives entirely in your browser — nothing to download, nothing to install. Design a front cover, and CoverSlay builds the full print wrap around it: spine width calculated from your page count, bleed included, 300 DPI out the door. Making a film instead? PosterSlay is built right in.

  • ✓ KDP & IngramSpark sizes
  • ✓ Full wrap + spine math
  • ✓ Poster billing blocks
  • ✓ Runs 100% online

Exports at 300 DPI with bleed
Start here — type your details, we’ll put them on the cover Works for books & posters. Change a word and the cover updates live.

Leave blank on a regular book. On a poster it sits above the billing block, like a real one-sheet.

Auto-place is on: title up top where eyes land first, subtitle under it, cast in the middle, author anchored at the base — balanced for the artwork you picked.

✦ Start from my story — describe it, get 3 cover concepts

Tell us what your book or movie is about in 2–3 sentences. CoverSlay reads the mood and genre words, matches them against the built-in art and template library, auto-places your title and author / cast, and lays out three concepts for you to approve or pass on.

Honest note: this story matching still runs over the built-in library shown on this page — no AI call is made here. For real AI art, use “Generate with AI” in the Background art panel: signed-in testers get live AI-generated backgrounds there now.

See it living on real objects

This is your current design, not a sample. Change a title, a color or the artwork above and every scene below updates instantly — the way Book Brush shows a book in the real world, built into CoverSlay.

On a phone — the ebook view most readers meet first, in the Kindle and Books apps.

The download composites your live design into the scene you are looking at, at 1600 px — ready for ads, launch posts and your store page.

Template library

Start from a design that already knows its genre.

Every template drops straight into the editor — words, fonts, colors and all — and stays fully editable. Faith and film are first-class citizens here, not an afterthought category. The ✦ AI Library is painted in-house for CoverSlay, and every paid plan includes the commercial license to sell what you build with it.

Why CoverSlay

Built for the two mistakes that cost authors money.

Most cover tools are graphic toys: pretty fronts, wrong files. Covers get rejected by KDP, spines come back the wrong width, and posters ship without a billing block. CoverSlay is built print-first.

1 · The wrap is calculated, not guessed

Tell CoverSlay your trim size, page count and paper, and the spine is computed from the printer's own paper thickness — then the full wrap is drawn to scale around your front cover, bleed included. What you approve on screen is the file the printer receives.

240 pages · cream paper · 6 × 9 trim → spine 0.600″ · full wrap 12.600 × 9.000″ · with bleed 12.850 × 9.250″ · export 3,855 × 2,775 px at 300 DPI

2 · Posters are a first-class product

PosterSlay lives inside the same studio: theatrical one-sheet sizes, a real billing block, festival laurels, and release lines. Filmmakers are not an upsell — they are half the house.

3 · Faith-first templates

Christian nonfiction, testimony, spiritual warfare, church and ministry design — a library built by people who publish in this world, instead of a romance-and-thriller catalog with a cross pasted on.

4 · Your art, or art made for you

Upload your own artwork, start from the curated library, or — at launch — describe the scene and generate a background that exists on exactly one cover: yours.

Questions, answered straight

Before you pay for anything, read this.

CoverSlay is in preview: the studio above is free to try, nothing is on sale yet, and there are no accounts or checkout on this page. These are the honest answers that will apply at launch, in plain language.

Will KDP and IngramSpark accept these covers?

Yes — print exports are built to their specs, not eyeballed. Pick Paperback or Hardcover and CoverSlay calculates the full wrap from your trim size, page count and paper: spine width from the printer's own paper thickness, 0.125″ bleed on every side, exported as a print-ready PDF at 300 DPI. Ebook covers export at exactly 1600 × 2560 px, the size Kindle asks for.

One honest last step is still yours: run the printer's own previewer before you publish. It takes a minute, and printers occasionally update their templates — the previewer is the final word.

Do I own my covers? Can I sell with them?

Yes. A cover or poster you finish and export is yours to sell with — on your books, your film, your ads, your store pages and your printed posters. No royalty, no extra license fee, no asking us first.

That includes AI background art generated for you at launch: art made from your description, for your cover, is yours to use commercially the same way. And anything you upload — a photo, a painting, your own artwork — stays your property, full stop. Just don't upload art you don't have the rights to use.

Does the AI write my title text?

No — and that's deliberate. At launch, AI paints background art only. Your title, author name, tagline and billing block are real typography that you type and control, set in real fonts at print resolution.

That's why nothing garbles. Image generators that try to draw words produce melted, misspelled letters; your name on your own cover should be spelled exactly the way you typed it, sharp enough for a bookstore shelf.

What formats do I get?

PNG, JPEG, PDF and TIFF, at print resolution. PDF is the file you upload to KDP or IngramSpark for print. PNG is best for screens, mockups and launch graphics. JPEG is the smaller, share-anywhere file. TIFF is the uncompressed, max-quality file printers and designers ask for.

Print book exports run at 300 DPI with bleed included. Posters export at theatrical sizes (27 × 40″ and down) at 150 DPI, the poster standard.

What happens if I run out of AI generations?

AI generation pauses. Nothing else stops. Your projects, your designs and your exports keep working — you can keep designing with the template library and your own uploaded art, and download everything as usual.

When paid plans launch, you can wait for your plan's generations to refresh next period, or pick up a generation pack. Pack generations sit in their own bucket and never expire.

How do refunds work?

Plainly: this preview is free, so there is nothing to refund yet. At launch, if a paid plan or pack isn't right, ask within 14 days of the charge and — as long as your paid generations are completely unused — you get a full refund. Once any paid generation has been used, that charge isn't refundable, and there are no partial refunds.

A refund ends the paid access it bought, right away. Files you already exported stay on your computer and stay yours to use. The full policy is in the Refund Policy linked in the footer.
