PublishDrive

Publishing

Ebook distribution aggregator that moved from a royalty-share model to flat-fee subscription pricing, so authors now keep 100% of the store royalty rather than splitting it with the platform

The short version

  • Each has a real cost: Kotobee interactive EPUB 3 features degrade or disappear in mainstream retail readers, Kindle in particular, so a book built around widgets and quizzes cannot simply be resold through ordinary retail channels later.; PublishDrive the flat-fee model works against an author with low or unpredictable sales, since the monthly subscription is charged regardless of whether the book earns enough royalty to cover it, unlike a royalty-share model that only costs money on actual sales.
  • They diverge on capability: Kotobee covers Interactive EPUB 3, PublishDrive covers Wide distribution.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Kotobee

  • Interactive EPUB 3 features degrade or disappear in mainstream retail readers, Kindle in particular, so a book built around widgets and quizzes cannot simply be resold through ordinary retail channels later.
  • Exporting a native app does not remove the app store obligations: you need Apple and Google developer accounts, you handle review submissions, and you own every rejection and update cycle.
  • There is no print workflow at all, so a title that also needs a paperback edition requires a separate layout tool and a duplicated production process.
  • It is a small vendor with a limited partner and integration ecosystem, which is a genuine concern for an institution embedding it in a multi-year curriculum programme.
  • Cloud hosting, DRM and user management are priced separately from the authoring licence, so the recurring cost of delivery, rather than the software purchase, is what the budget has to carry.

PublishDrive

  • The flat-fee model works against an author with low or unpredictable sales, since the monthly subscription is charged regardless of whether the book earns enough royalty to cover it, unlike a royalty-share model that only costs money on actual sales.
  • The free tier gives access to only 29 of roughly 49 total channels, so testing the platform for free does not represent the full distribution reach a paid plan provides.
  • Subscription service royalties (25-60%, typically around 55%) are lower and more variable than standard retail royalties, so an author distributing heavily through subscription channels should model that lower rate specifically rather than assuming a flat 70%.
  • As an aggregator, PublishDrive sits between the author and each retailer, so account-level issues or policy changes at an individual retailer (Amazon, Kobo, Apple) can affect distribution in ways the author does not directly control.
  • Multiple books beyond the Starter plan 3-book cap require a higher tier, so an author with a larger catalogue needs to check the cost of higher plans against direct multi-retailer management before committing.

Answered from the vendors’ own pages

Kotobee: Can I sell a Kotobee book on Amazon?

You can sell a stripped-down EPUB, but the interactive content that justified the tool will not render. Treat retail as a separate, simpler edition.

PublishDrive: Does PublishDrive take a cut of royalties?

No, not on paid plans. It moved from a royalty-share model to flat-fee subscription pricing, so authors keep 100% of what each retailer or subscription service pays.

Kotobee: Does Kotobee publish the app to the stores for me?

No. It generates the application; you supply the developer accounts and go through Apple and Google review yourself, including every subsequent update.

PublishDrive: Is the free plan worth using to test the platform?

It gives access to only 29 of the roughly 49 total channels for one book, so it is a limited preview rather than the full paid-plan experience.

Kotobee: Is it suitable for a trade fiction publisher?

No. It is built for education, training and reference material where interactivity and controlled access are the point.

PublishDrive: How does it compare to Draft2Digital?

Both are wide-distribution aggregators; the key difference to check is Draft2Digital retains a small percentage-based fee model in most cases, while PublishDrive is flat-fee subscription-only on paid plans.
