The problem it solves

Turning a book into an audiobook usually means hours of manual narration or expensive freelance voice work. Finding chapter breaks and splitting text into readable chunks is tedious and easy to get wrong. You want listenable audio files organized by book, not one giant unmanageable recording.

Who it fits

Authors, publishers, or content creators who want an audiobook version of a written PDF without recording it themselves.

How it works

  1. You upload a book PDF through a simple upload form
  2. The system extracts the full text from the file
  3. AI detects chapter breaks and splits the text into natural, sentence-safe chunks
  4. Each chunk is converted into narrated audio using OpenAI
  5. The finished audio files are saved into a Google Drive folder named for the book
What you get

Audiobook chapters ready to review

You get your book automatically split into chapters and narrated into audio files, organized and saved to Google Drive for easy listening.

What you get

A set of organized MP3 audio files for each chapter, saved in a dedicated Google Drive folder.

What you need

A Google Drive account and an OpenAI API key.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
