“Sindo Hane” has published more than 100 novels since April 2025

I recently received a tip about an author known as Sindo Hane who has been enormously productive this spring, publishing more than 100 novels at Amazon, all available to read through Kindle Unlimited. (The easiest way to quickly scan all of Hane’s work is through this Goodreads page.)

Sindo Hane is most certainly a pen name for either an individual or a group of people who are populating Amazon with low-quality, AI-generated genre fiction. At first, most of the novels were clocking in at 70–80 pages; more recently published novels are about double the length. Some are labeled as “illustrated,” but that stretches the definition of the term. All are torturous to read. The covers and titles are formulaic and clearly trope- and keyword-driven, e.g., The Shroud of Blackwood ManorMurder in Lavender TimeThe Chronos Deception, and so on.

The books are getting scant attention from anyone, but if enrolled in KU, I guess there’s potential for a few pennies earned per book, and if one has thousands of titles available (Sindo Hane is well on their way to doing just that), then maybe it becomes worth it? This content-farming model has been around for a long time, only now it’s AI powered. Sindo Hane has no online presence aside from an X account, @sindohanemys.

I am very curious to see if and when Amazon draws any kind of line for such activity.

For the heck of it, I bought (for free) When the Village Clock Lied, by Sindo Hane. I then ran the prologue through 3 AI detectors (Pangram, GPTZero and ZeroGPT). The results:

  • Pangram “We are strongly confident that the document contains AI-generated writing (99.9%).”
  • GPTZero: “We are highly confident this text was AI generated (100%).”
  • ZeroGPT: “Your Text is AI/GPT Generated (96.64%).”

I don’t trust these detectors when their scores are +/- 70%, but three different findings near 100% is uncontestable.

There’s no point in raising this with customer service… and everyone else working for Amazon is anonymous. I suppose I can try PR.
