A report, not another tool
You do not receive a login, credits or a dashboard to figure out yourself. Kokunari collects the marketplace data, validates the competitors, analyzes the written reviews and delivers the completed report through a shareable link.
What you receive
Each section explains the evidence in plain English and finishes with practical recommendations for your product and Amazon listing.
See why people buy, what they value, what disappoints them and which questions remain unanswered.
Identify repeated problems that can be solved through the product, packaging, instructions or expectations.
Compare the products, customer feedback and listing promises shoppers see before making their choice.
Turn the findings into a concrete message hierarchy for your title, images, A+ content and campaigns.
Sample report content
The report separates interesting observations from actions worth taking. In this example, setup doubts and unclear fit expectations matter more than adding another feature claim.

Operator judgment behind the AI
I started selling on Amazon at 21 and spent more than seven years building products, listings and an Amazon-focused agency.
I have seen brands add more keywords, more features and more creative without answering the one question that matters: what is stopping the customer from choosing this product? The Kokunari report was built to answer that question with evidence—and turn the answer into action.
