What the average indie author spends on marketing

You wrote the book. But books only reach people who find them.

Podcast listeners are a completely different audience from book buyers. Most authors never reach them because production is expensive, time-consuming, and technical.

Audio production is expensive

Professional narration runs $200–$2,000 per finished hour. A single book can cost $7,000+ to produce as an audiobook, and then you're splitting royalties on top of that.

Marketing eats your writing time

Authors are expected to post daily on social media, run ad campaigns, and build email lists, all while writing the next book. Most can't sustain it.

Ads are a gamble

Amazon ads, Facebook ads, Google ads. Authors spend hundreds per month with no guarantee of a return. Most break even at best.

Podcast listeners are a different audience

584 million people listen to podcasts. Most of them aren't browsing Amazon for books. Without a podcast, you're invisible to them.

From manuscript to podcast in five steps

You provide the book and a short voice sample. We handle the rest.

01

Send us your book

PDF, ePub, Word, any format. We segment the content into logical episodes aligned with your chapters and ideas.

02

Send us a voice sample

We need about 30 minutes of clean audio to build a high-fidelity clone of your voice. This can be an existing recording, a podcast interview, or a fresh read-through we guide you on.

03

We generate the scripts

Your book's content is transformed into podcast scripts built for how people actually listen.

04

Produce the episode

Audio is generated in your cloned voice with a dedicated host to introduce and close each episode. Show notes are created for every episode.

05

You review, we publish

Nothing goes live without your approval. Once you sign off, we deliver files ready for Spotify, Apple Podcasts, and every major platform.

Named Testimonial
Having spent over 30 years helping executives and teams expand their collaborative performance, I wrote Full Contact Performance to make my work more accessible to everyone. A book is powerful, but it's only one format. Bryson made it easy to turn my book into a short weekly podcast series narrated in my own voice, for a fraction of what traditional audio production would cost. He has created a simple and intuitive system requiring no technical expertise on my part that lets me review and adjust each script so it really sounds like me. Bryson's Castify platform has given my book a second life in a format people can take with them wherever they go. Every author should have Castify in their corner!

Common questions

Yes. We use professional-grade voice cloning trained on about 30 minutes of your audio, which captures your unique tone, rhythm, and speech patterns. You approve everything before it goes live. If it doesn't sound right, we adjust until it does.

The main time investment is upfront: uploading your book and providing about 30 minutes of voice audio (which can be an existing recording). After that, you just review each episode as it's delivered. Most authors spend 5–10 minutes per episode on review.

A typical nonfiction book yields 20–40+ podcast episodes. Once you've covered the full book, we can create bonus content: reader Q&A episodes, current events tie-ins, companion content, and more.

100%. You retain full ownership of your book content and every generated episode. Castify is a service provider. We have no claim to your intellectual property.

Major platforms including Spotify and Apple Podcasts currently allow AI-generated voice content with proper disclosure. We include appropriate disclosures in every episode's metadata.

Yes. No long-term contract. Cancel before your next billing cycle and you're done. All episodes already produced are yours to keep.
