SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It removes the guesswork of creating visually compelling, genre-appropriate AI cover prompts and converts your story details into production-ready prompts sized for Kindle covers.

Core Features & Use Cases

Cover-prompt generation: Produces 3-5 distinct cover concepts tailored to your manuscript’s visual essence.
Story-aware prompt synthesis: Reads project materials like themes, characters, world, and tone to generate consistent, non-cliché design directions.
Kindle-dimension optimization: Targets 1600 x 2560 (1:1.6) so prompts align with typical cover workflows.
Image-only or text-inclusive modes: Supports image-only (negative space for later title overlay) and text-inclusive (title/author baked into the generated image).

Quick Start

Run /holocron:cover for your current project to receive multiple Kindle-optimized cover prompt options for immediate image generation.

FAQPage Schema

How do I generate Kindle book cover prompts from my story materials?▼

Kindle-dimension optimization targets the 1600 x 2560 pixel ratio (1:1.6) for cover prompt generation. This specific sizing aligns your generated cover concepts with standard Kindle publishing workflows and requirements.

How do I create book cover concepts that leave space for title text?▼

To create book cover concepts with space for title text, use the image-only mode during prompt generation. This mode produces prompts designed with negative space, allowing you to overlay titles and author names later in your design workflow.

Can I generate AI cover art prompts that include the book title and author name?▼

Yes, you can generate AI cover art prompts with text inclusive of the book title and author name. By using the text-inclusive mode, the generated prompts will direct the image generator to bake the title and author text directly into the cover art.

What is the best way to get multiple concept variations for a novel cover design?▼

Story-aware prompt synthesis reads project materials like themes, characters, world, and tone to generate consistent design directions. It ensures your generated cover concepts reflect the visual essence of your manuscript without relying on clichés.
