What is the BookBloom Chrome Extension?

The BookBloom Chrome Extension is available in the Chrome Web Store, bringing BookBloom's browser-assisted KDP workflow into supported Amazon and KDP pages.

The extension adds on-page estimates and shortcuts, then hands supported detected fields to BookBloom web tools when you choose to open them. It is designed to reduce repetitive copying rather than replace Amazon or KDP reporting.

Key Features

Instant BSR to Sales Estimates

On supported Amazon product pages, the extension detects BSR and shows a modelled daily-sales range. Amazon does not publish a direct BSR-to-sales conversion, so the result is an estimate rather than reported sales data.

One-Click Compliance Checks

Send detected KDP metadata to BookBloom's compliance checker to review common policy-sensitive terms and metadata risks before publishing.

Auto-Prefilled Calculators

Supported fields such as BSR, price, format, marketplace, and page count can be detected and sent to a BookBloom calculator when you explicitly choose a prefilled handoff.

Privacy-First Design

We know privacy is important to authors. That's why the BookBloom extension is built with a privacy-first approach:

  • Local by default - On-page analysis, settings, counters, and BSR history remain in your browser
  • Explicit handoff - Detected values are sent to BookBloom.io only when you choose to open a prefilled BookBloom web tool
  • Limited host access - Content scripts run only on the Amazon storefronts and KDP domain declared in the manifest

What's Next?

BookBloom continues to refine the extension based on product testing and user feedback. Potential future improvements include:

  • Real-time compliance warnings while typing in KDP fields
  • Competitor analysis directly on Amazon search results
  • Historical BSR tracking for books you're watching
  • Batch analysis for multiple books at once

Join the Community

BookBloom is built for independent KDP authors who want faster research and metadata-review workflows. The extension puts those browser-assisted tools on the supported Amazon and KDP pages where they are useful.

Install the extension if the current workflow is useful to you, and share feedback on the features you would most like us to improve next.
