You can use the information provided in the report to refine your work to better meet the expectations of your targeted audience, to draw comparisons with popular authors when marketing your work, or to differentiate your work from current trends in literature.

How is my Helix Review generated?

The interior of your manuscript will be indexed and analyzed, then statistics specific to your content, use of dialog and description, vocabulary, sentence and paragraph structure, pacing, and theme treatment are compiled. Based on these statistics, your manuscript will be scientifically compared to more than 100,000 books listed in The Book Genome Project. Your personalized report displays how your content, style, setting, and approach compare with published authors in general as well as successful authors within your selected genre.

Is the Helix Review a review of my work?

The Helix Review provides valuable insight into how your manuscript and style stack up against published authors with a similar subject matter or genre. It does not, however, quantify your writing as good or bad, nor does it make specific recommendations to improve your writing or style.

Who reads my manuscript?

No carbon-based beings are involved in the process. In order to provide a completely objective report, your manuscript will be indexed, electronically analyzed, and compared with published books listed in The Book Genome Project. A personalized Helix Review for your manuscript will be automatically generated.

What is The Book Genome Project?

The Book Genome Project is an indexed repository of more than 100,000 published works by popular authors representing all genres. The Book Genome is derived through the analysis and comparison of books, based primarily on language, character, and theme. These components are mined and analyzed in order to sift, organize, categorize and ultimately separate one book from another. The fundamental goal of the project is to develop ways to intelligently understand the content and make-up of books, then to apply that knowledge so that lesser-known books and authors are more easily discovered.

Will my book become part of The Book Genome Project?

Additions to The Book Genome Project are currently limited to titles submitted by traditional publishing houses.
