Best AI Image Generator for Book Covers

For book covers, Ideogram 3.0 is the top choice due to its superior text rendering (14 credits/gen). GPT Image 1.5 (18 credits) excels at following complex briefs, while FLUX.2 Pro (18 credits) delivers photorealistic scenes.

Budget-conscious creators can use Nano Banana 2 (free tier) for painterly styles. Key factors: typography clarity (Ideogram), prompt adherence (GPT), and photorealism (FLUX.2 Pro).

All FluxNote models allow commercial use with no watermark.
