Made with InkFoundry Studio

Covers and pages from real books made with the app for Amazon KDP: two coloring books and two short guides.

Coloring pages are cleaned to pure black and white and rebuilt at 400+ DPI for print.

How it works

Four steps, one app. Every step saves as you go, so you can stop and pick up later.

Step 1

Find a niche worth making

Enter a seed topic. InkFoundry Studio pulls live Google and Amazon search suggestions (what shoppers actually type) and has AI rank the sub-niches by demand, competition and opportunity, with product ideas and keywords.

Scores are estimates from search signals, not sales data, so treat them as a starting point.

Step 2

Make the product

  • Coloring books: AI page ideas, line art, clean black-and-white pages. Untick any you don't like and regenerate just those.
  • Info books: an outline you can edit, then chapters written one at a time.
  • POD designs: transparent 300 DPI PNGs sized for shirts, mugs, stickers, posters and totes.

Step 3

Get print-ready files

One click builds the KDP interior PDF and a wrap-around cover sized with KDP's spine formula: correct trim, bleed and embedded fonts. Covers are upscaled for print, and a print check shows any image that's too soft.

Also: Kindle ebook (EPUB), printable Letter and A4 PDFs for Etsy, and listing images.

Step 4

List it and publish

Write listing creates Etsy and KDP copy within each platform's limits: titles, descriptions, 13 Etsy tags, 7 KDP keyword boxes and categories.

KDP has no upload API, so the KDP upload helper walks you through KDP's pages in order, with a Copy button for every field and the exact settings to choose.

Questions

What do I need to run it?

Windows 10 or 11 (64-bit) and an internet connection for cloud AI and niche research. For free local image generation you also need an NVIDIA graphics card with about 8 GB or more of video memory.

How much do the AI services cost?

That depends on the provider and model you choose; you pay them directly on your own account. Images typically cost a few cents each in the cloud, and nothing with local AI. Before every big job the app shows an estimate based on published prices and your own recent jobs.

Will it make me money?

No tool can promise that, and InkFoundry Studio doesn't. It makes researching and producing good products faster; what sells depends on your niche, quality, listings and marketing. Niche scores are estimates, not sales data.

Does Amazon allow AI-generated books?

KDP accepts them, but you must tell KDP which content is AI-generated when you publish, and books must meet KDP's content guidelines. The KDP upload helper shows you what to answer. Make fewer, better books: KDP limits how many titles you can publish per day and removes low-quality content.

Does it upload to KDP for me?

No. KDP has no publishing API and doesn't allow automated uploads, so the KDP upload helper walks you through KDP's own pages with every value ready to copy and paste.

Is there a Mac version?

Not yet: InkFoundry Studio is for Windows 10 and 11.

What happens to my data?

Your projects, settings and keys stay on your computer. The app sends requests only to the AI and search services you use, directly from your PC. There's no tracking or analytics. See the privacy policy.

Can I get a refund?

Yes, within 14 days of purchase. Email inkfoundrystudio@outlook.com.
