Book Cover Generator
Creating AI-powered cover art from your manuscript
Generating a cover brief
Open the Export modal from the Publish section, then click the Book Cover button. Click Generate Cover Brief. The AI analyzes your manuscript data and produces a creative brief with mood, color palette, imagery description, composition suggestions, genre conventions, and typography direction.
The brief panel is collapsible and shows all elements of the creative direction. Review it to ensure the AI understood your story's visual identity before generating images.
Generating and selecting cover concepts
Click Generate Cover Concepts to create three cover art variations from the current brief. Image generation takes a moment since each concept is generated individually. The concepts appear in a grid once complete.
Click Approve on the concept that best fits your vision. You can regenerate concepts at any time if none of the options work. Approving a concept unlocks the finalization phase.
Cover art is generated without text or lettering. Title and author name are composited separately so you have full control over typography.
How covers are used in export
When you export an EPUB, Bookshaper checks for an approved cover with a saved final image. If found, it embeds the cover as the first page of the EPUB and registers it as the cover image in the package metadata. E-readers display this image as the book thumbnail.
Cover images are stored in your project's assets/covers/ directory. The final composited cover is saved as final-cover.png at 1600×2560 resolution, suitable for ebook distribution.
In BYOK mode, cover generation requires an OpenAI API key for image generation, even if you use a different provider for text analysis. Add your OpenAI key in Settings.
