How it works
One workspace from idea to export. You review and approve every page.
Plan the book
Pick a theme, audience, page size and one of four monochrome style presets.
Generate pages
Use an administrator-approved image model with your own OpenRouter key. Jobs run in a queue with retries.
Check and fix
Automated checks flag gray pixels, heavy black areas, low contrast and cut-off art. Crop, threshold and fit to page.
Assemble and export
Add title and copyright pages, reorder, preview, and export PDF/PNG/ZIP with a preflight report.
Four monochrome styles, each with its own rules
A solid silhouette with white details is not the same as an outline page. Each preset has its own prompt template and quality criteria. The images below are hand-made vector illustrations of each style, not AI output.
Solid black silhouette shapes containing white fillable detail areas. Different from outline pages: large areas are filled black.
Uniform black outlines on a white background. Classic coloring-page style with open white regions to color.
Detailed black-and-white ornamental artwork with fine decorative linework for experienced colorists.
Bold geometric or repeating decorative patterns with strong black/white contrast.
Built for monochrome, not adapted to it
General image tools drift toward gray shading, color tints and cropped subjects. Monochrome Studio AI uses style-specific prompts and checks so your pages stay black and white, centered and printable.

Frequently asked questions
Do I need my own AI API key?
Yes. Generation uses your own OpenRouter API key. Usage is billed by OpenRouter according to their pricing and terms. We never use a hidden fallback key.
Will my book be approved by Amazon KDP or sell on Etsy?
We cannot guarantee approval or sales. The app helps you prepare files and runs heuristic checks, but you must review every page and verify current platform requirements.
Who owns the generated images?
Rights in AI-generated content depend on your AI provider's terms and the law where you live. Access to this app does not grant copyright or exclusivity.
How do I get an account?
Accounts are created automatically after a verified purchase. You will receive an activation email to set your password.
Can I export my data?
Yes. Your images, PDFs and a JSON export of your account data are always available from your account.
