The claim
Make AI colouring books and journals in minutes, sell on Amazon.
A perennial TikTok/YouTube 'KDP hustle' topic with steady but not rising buzz.

What the evidence shows
Adult colouring is a real, steady market, and some sellers with carefully made, niche-specific series do earn. But low-content books are badly oversaturated, unedited AI line art draws bad reviews (broken lines, odd anatomy), and the three-per-day cap and disclosure rules still apply. Success looks like building a catalogue over time with manual clean-up and often Amazon ads, not quick wins.
Realistic earnings: Typically £0–£50 a month in year one, spread across a catalogue of 20+ books; single titles rarely sell.
Limitations
Earnings ranges are typical outcomes for a beginner, drawn from the sources; some people do far better or worse. Platform rules change often, so check the latest policy before you start.
Works for some, not most.
