Each card gives the format, the work involved, price evidence from the snapshot or from the marketplace's own rules, where it sells, and whether Inkfluence AI can make it. We make Inkfluence AI, so we have marked plainly the 4 formats it does not make or only partly makes.
1. Ebooks and practical guides
Inkfluence makes it A PDF or EPUB that teaches one thing or solves one problem: a how-to, a beginner guide, a recipe collection, a travel guide. The oldest digital product and still the simplest to make and explain.
- Effort:
- A weekend to a few weeks of writing and editing, plus a cover.
- Price evidence:
- Gumroad snapshot: median $29.99, middle half $19.99 to $52.48 (36 USD-priced ebooks). Kindle: the 70% royalty band is $2.99 to $12.99.
- Where it sells:
- Gumroad, Payhip, Etsy, your own site, and Kindle.
- Inkfluence AI:
- Writes the chapters from your idea; PDF on every plan, EPUB and Word on paid plans or credits. See the AI ebook generator.
2. Kindle ebooks and paperbacks on Amazon
Inkfluence makes it The same book sold through Amazon KDP as a Kindle ebook and a print-on-demand paperback. Amazon prints each copy when it sells, so there is no stock to buy.
- Effort:
- As for an ebook, plus a print interior at your trim size and a wrap cover with a spine.
- Price evidence:
- Kindle 70% band $2.99 to $12.99. A paperback's minimum price is its printing cost divided by the royalty rate; a 200-page black-ink book costs $3.40 to print.
- Where it sells:
- Amazon KDP, plus wide distribution through other retailers.
- Inkfluence AI:
- A KDP package: interior PDF, wrap cover with spine, EPUB and a cover image, on paid plans or credits. See the KDP self-publishing guide.
3. Workbooks and worksheets
Inkfluence makes it Exercises, prompts and space to write: a self-help workbook, a business planning workbook, a set of maths worksheets. Buyers pay for the doing, not just the reading.
- Effort:
- A weekend for a short workbook; longer if every page is designed.
- Price evidence:
- Gumroad: median $19 (22 workbooks). TPT: workbooks median $12.25, worksheets median $7.23.
- Where it sells:
- Etsy, Gumroad, Teachers Pay Teachers for classroom material, Amazon as a paperback.
- Inkfluence AI:
- A workbook format with exercises; ruled answer lines and write-in boxes print in the PDF. See the workbook generator.
4. Guided journals and day challenges
Inkfluence makes it Prompts with room to answer, often over a set number of days: a 30-day gratitude journal, a grief journal, a 21-day habit challenge.
- Effort:
- A day or two to write the prompts; design is where the time goes.
- Price evidence:
- Gumroad: median $15, middle half $9 to $30.50 (28 journals).
- Where it sells:
- Etsy (printable), Gumroad, Amazon as a paperback.
- Inkfluence AI:
- Written as a workbook or a day-by-day challenge with answer lines. See the journal generator.
5. Printable and digital planners
Not Inkfluence Calendars, trackers and planning pages to print, or hyperlinked PDFs for tablet apps. A crowded format where design and a clear niche (teachers, nurses, homeschoolers) decide sales.
- Effort:
- Days to weeks of layout work; hyperlinked planners take longer.
- Price evidence:
- Gumroad: median $19.49, middle half $11.99 to $27.75 (28 planners).
- Where it sells:
- Etsy above all, then Gumroad and Payhip.

6. Coloring pages and coloring books
Inkfluence makes it Line art to colour, sold as printable page packs or as printed coloring books. Children's, adult detailed, and bold-and-easy styles each have their own buyers.
- Effort:

7. Children's picture books
Inkfluence makes it An illustrated story for young children, sold as a printed book or a PDF. Characters that look the same on every page are the hard part.
- Effort:
- Writing is short; illustration, layout and print setup take most of the work.
- Price evidence:
- Mostly sold in print on Amazon. Colour printing on KDP costs more than black ink, which sets the floor on price (standard colour, 72 to 600 pages: $1.00 + $0.0255 a page).
- Where it sells:
- Amazon KDP paperbacks, Etsy as a PDF, gift and personalised-book shops.
