Consistent AI Character Art for Audiobooks — ACX Covers That Brand Your Series

One series character. Locked. Render it across 2400x2400px ACX/Findaway Voices covers, YouTube narration sample thumbnails, and social promo art — without re-commissioning per book.

The problem

An audiobook narrator producing a 10-book series for ACX needs square cover art (2400x2400px at 72 DPI minimum, RGB) for every title. Commissioning a cover illustrator per book costs $200-400 each — that's $2,000-4,000 across a series before the narrator earns back royalties. Worse, if different illustrators handle different books, the protagonist's face drifts across the series box set. ACX listeners browsing by series cover grid notice inconsistency immediately. Narrators also need YouTube sample video thumbnails and social media promo art featuring the same character — multiplying the per-book design cost.

How audiobook narrators and producers use EZ Character

  • ACX square cover series pack

    Generate the protagonist at 2400x2400px from the locked reference for book 1. For books 2-10, generate the same character in new poses matching each book's plot — same face, fresh cover per title. 10 covers from one canonical reference, no illustrator drift.

  • YouTube sample video thumbnail

    Audiobook narrators use YouTube sample videos (5-10 minutes) to sell listeners on a book. Generate a 1280x720px thumbnail featuring the protagonist from the locked reference with room for title text overlay. Consistent character branding across a channel with 50+ sample videos.

  • Social media promo art — Instagram + Facebook

    Narrators promote new releases on Instagram (1080x1080px) and Facebook (1200x630px). Generate the character in platform-optimized crops from the locked reference. Same face on every release-day post across a 10-book series.

  • Series box set art for Audible collection pages

    When a series completes, Audible promotes it as a box set. Generate the entire cast in a group composition from each character's locked reference — all faces consistent, one polished box set cover without re-briefing a cover designer.

Which tier fits this work

Start with a Credit Pack. A 10-book audiobook series needs roughly 10 covers + 30 social media assets + YouTube thumbnails over a 2-3 year production cycle. The 3,200-credit pack ($40, credits never expire) covers the full series arc on a narrator's timeline — generate as new titles release without a monthly subscription ticking.

Frequently asked questions

Will the art meet ACX cover requirements (2400x2400px square)?
Yes. ACX requires a minimum of 2400x2400px square at 72 DPI in RGB color. Generate at 2400x2400px and you meet spec directly. ACX also requires no misleading imagery — the locked reference ensures your protagonist looks the same as described in the book, reducing rejection risk.

Can I use this for Findaway Voices and Author's Republic covers too?
Yes. Findaway Voices and Author's Republic both accept 2400x2400px square JPEG covers. Generate once, export to all three platforms. The character stays consistent whether a listener finds you on Audible, Apple Books, or Google Play Audiobooks.

Does the character art work for audiobook Facebook/Instagram ads?
Yes. Audiobook narrators run FB/IG ads targeting genre readers. Generate the character at 1200x628px (Facebook feed) and 1080x1080px (Instagram) from the locked reference. Same face across your ad creative and your ACX cover builds listener trust.

Are paid tiers safe for commercial audiobook publishing on Audible?
Yes — all paid tiers include full commercial rights. You can use generated character art on ACX/Audible covers, Findaway Voices titles, YouTube monetized sample videos, and any platform where you earn royalties. The art is yours for commercial audiobook publishing.

What if I narrate multiple pen names across different genres?
The 3,200-credit pack covers character references for 3-4 pen names. For narrators with 5+ active pen names, MAX ($60/mo) lets you generate character art for every series under every pseudonym — no credit-counting across your entire catalog.
