What they did
Before ordering inventory, the author asked Claude Code to read the 1-star reviews of a best-selling product.
How it went
He reports Claude found the pattern: 'The product dies around day 30. The return window closes at day 30.' The run cost $0.0477 with pay-as-you-go API usage.
We only report what the source says. Results are self-reported unless noted.
Worth knowing
The headline claim that this replaced a $359/mo seller suite is the author's framing.
Copy-paste prompt
Starter prompt (written by us)
Here are all the 1-star and 2-star reviews for [ASIN] with their dates and any 'used for X days' mentions: [paste]. Find failure patterns, especially WHEN the product fails (days or weeks of use) and HOW. Count how many reviews support each pattern and quote short supporting snippets with review dates. Tell me whether the timing lines up with Amazon's return window.
