What our authors say
Real authors already publishing winning niches every week.
“I've been on the Pro plan for 3 months and launched 4 books already in the top of their category. The perimenopause signal came 3 weeks before the niche got saturated.”
María G.
KDP Author · Madrid
“The radar spotted GLP-1 journals when there was zero competition in Spanish. I published in 2 weeks and I'm still #1 for that keyword.”
Carlos R.
Self-Publisher · Bogotá
“The profitability score saves me hours of manual validation. I used to spend days figuring out if a niche was worth it — now I see it at a glance.”
Laura P.
Author · Buenos Aires
“The US market insights are incredibly accurate. I've been riding the ADHD + Perimenopause wave since week one. Revenue is up 340% this quarter.”
James K.
KDP Author · London
“I hesitated about the price at first, but I recovered the investment in the first month with a gut health book the radar flagged as a GOLD signal.”
Sofía M.
Author · Mexico City
“The BookTok data alone is worth the subscription. I spotted the sourdough journaling trend 4 weeks early. First-mover advantage is real.”
