The short version

Each has a real cost: Kindle purchased e-books are DRM-protected and tied to an Amazon account by default, so a Kindle library is not portable to another platform's app without stripping protection through third party tools.; 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.
They diverge on capability: Kindle covers E-book reading, Kotobee covers Interactive EPUB 3.

Where each one falls short

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

Kindle

Purchased e-books are DRM-protected and tied to an Amazon account by default, so a Kindle library is not portable to another platform's app without stripping protection through third party tools.
Kindle Unlimited only includes a rotating subset of titles, not the full Kindle Store, so many popular or newly released books still require a separate purchase even with an active subscription.
Public library e-book lending through Kindle depends on library systems like Libby/OverDrive integration working correctly, and syncing issues between library loans and the Kindle app are a recurring user complaint.
Amazon can and has remotely removed purchased content from user accounts in rare disputed-rights cases, which is a real, if uncommon, risk of the DRM-locked model.
Reading on a phone or tablet inside the app lacks the e-ink glare-free reading experience of a dedicated Kindle device, which is a different purchase entirely.

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.

Answered from the vendors’ own pages

Kindle: Is the Kindle app free?

Yes, the app itself is free; you pay for individual e-book and audiobook purchases, or optionally subscribe to Kindle Unlimited.

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.

Kindle: Can I read Kindle books on a non-Amazon device?

Somewhat; Kindle apps exist for most major platforms, but the books remain DRM-locked to your Amazon account rather than being a portable file format.

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.

Kindle: Is this the same as Kindle Direct Publishing?

No, Kindle Direct Publishing is the separate author-facing platform for publishing and selling books; this is the consumer reading app.

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.
