KDP Niche Scorecard Generator とは？
KDP Niche Scorecard Generator is a free planning tool for self-publishers and digital product builders. It scores a book or template idea across buyer intent, giftability, competition clarity, production simplicity, and evergreen demand. The goal is to help creators pause weak ideas earlier and focus on clearer niches. It is not an Amazon ranking predictor, and no sales or ranking results are guaranteed.
