User reviews

The 'KDP Spy by Book Bolt' Chrome extension has mixed reviews. Many users report functionality only after pinning the extension and using Amazon US site, while others note it disappears or causes the page to refresh, disrupting use. It provides valuable keyword and category data useful for KDP research and saves time, but is hindered by bugs, compatibility issues (especially outside amazon.com and in browsers like Opera), and conflicts with VPNs or security software. Users appreciate the concept but desire fixes to make the extension stable and reliable.

Pros

When used on Amazon US and after pinning the extension, it works as intended for some users.
The extension provides useful keyword and category information useful for KDP research.
Some users find it saves time and appreciate the fast results compared to manual research.
Support and steps provided by the developers or community helped certain users to get it working.
The keyword tab functionality works for some users even if search has issues.

Cons

Extension causes Amazon page to refresh after clicking the start/search button, which closes the extension popup prematurely.
Does not work properly on Amazon sites other than amazon.com, such as amazon.co.uk, or in some browsers like Opera, leading to failure or redirection to install page.
Many users experience the extension disappearing or becoming unresponsive shortly after activation.
VPNs and threat protection software interfere with the extension's functionality, causing it to malfunction or close unexpectedly.
General bugs and glitches make the extension unreliable, with repeated reports of it not working despite reinstalling and troubleshooting.

Recent reviews

Same thing is happening to me as other reviews I've read. Does not work at all, amazon (US) refreshes the page. I've reinstalled, cleared cache, and pinned it. And unpinned, and pinned again. Nothing. Must be a glitch?

Not happy with this new version. I waited to write the review until after I had worked with it some. Absolutely terrible.

Be*****, 2025-04-21

It works perfectly for me. I read the steps and reviews, so I made sure to pin the extension and I am using Amazon from the US as suggested.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

KDP Spy by Book Bolt requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
