Audiobook Production and Distribution

How the BookBird Author Score works

Built for self-published authors, from facts anyone can check: each vendor’s own pages, read on October 7, 2026, and US Google search volumes (Google Ads data via DataForSEO). Nobody pays to be listed, and no score is adjusted by hand. We did not test the apps by writing a book in them; the score measures what they do for an author, what they cost and how widely they are used.

• Author jobs, 50 points. Each category has a list of jobs an author needs that kind of software to do. A job counts only when the vendor’s own pages say the product does it; a job they do not mention earns nothing, and the product page says which ones.
  • Audiobook production: human narrators, aI narration, distribution to stores, royalty share or pay up front, non-exclusive option and royalty rate stated.
• Cost, 25 points. What one year costs a single author on the cheapest plan with a USD price. A one-time licence is spread over 3 years. A free plan, or a platform that takes no upfront fee, earns all 25; the dearest product in the category keeps 5.
• Adoption, 25 points. How many people in the US search Google for the product by name each month: 20 points on a log scale against the most searched product in the category, and 5 for the trend, comparing the last three months with the first three of the year.

The score is the points earned divided by the points that could be checked, on a 10-point scale. A part with no data (no USD price, no search volume) is left out rather than guessed. How long a product has existed is not scored: few vendors state it. Review sites are not used: for most of these products the profiles rate the whole company or hold a handful of reviews.
