AI Book Cover Generator: The Complete Guide for Authors
AI book cover generation refers to using artificial intelligence tools to create professional-quality book cover art for fiction, non-fiction, and academic publications. AI-generated book covers reduce design costs from $300-2,500 to the cost of a subscription month, and provide concept variations in minutes rather than weeks.

Key Takeaways
-
GLMImage is the best AI for book covers requiring text — 91.16% on the CVTG-2K benchmark for titles and author names in both English and Chinese, which usually eliminates manual typography work.
-
Genre-specific prompting is essential—romance, thriller, sci-fi, and non-fiction each have distinct visual codes that must be specified in prompts for market-appropriate covers.
-
Successful AI book covers follow a 50/50 rule of thumb: half image generation, half refinement in design software. Professional authors use AI for concept and imagery, then refine typography, layout, and color grading.

Frequently Asked Questions
What is an AI book cover generator?
A text-to-image tool aimed at cover art: it generates the illustration and — with models like GLM-Image — the title and author text in the image, so you get a complete front cover in one step.
Do I still need a designer?
For a commercial release, a designer pass helps with thumbnail legibility and series consistency. Many indie authors publish AI covers directly, especially in genre fiction.
What size should I generate?
Aim for at least 2,560 × 1,600 pixels — Amazon KDP's recommended ebook cover size — in portrait orientation.
Can AI handle the title text in Chinese?
Yes — GLM-Image renders Chinese and English titles accurately (91.16% on the CVTG-2K benchmark), which matters for translated editions.
