Adobe InDesign: For fixed-layout and designed digital publications where typographic and layout control matters more than interactivity

Interactive EPUB authoring that also exports native mobile apps and hosted libraries
As of 31 August 2026, Kotobee is free to use. An Egyptian authoring tool for interactive ebooks with video, 3D objects and quizzes, which can export the same book as an EPUB, a web app, a desktop app or a native iOS and Android application. Softwr lists it under Publishing. Kotobee is available on Windows, macOS, Web, iOS.
Overview
Kotobee Author produces interactive ebooks built on EPUB 3, with embedded video and audio, 3D models, question banks, self-assessment quizzes, book-in-book embedding and interactive widgets. The same project exports as a standard EPUB, a web application, a Windows or macOS desktop application, or a native iOS and Android app. Kotobee Cloud and Kotobee Library provide hosting, user management and DRM controls for organisations that want to deliver books to a known population rather than sell them publicly. The export to a native mobile app is the capability that decides purchases. For an education publisher, a training department or a ministry curriculum programme, the distribution channel is often a branded app that learners install, not a retailer listing, and building that app conventionally means commissioning developers. Kotobee turns the book into the app. That matters most in markets where the education sector distributes directly to institutions and where regional retail ebook channels are weak, which is where the company has built its business. The corresponding limit is that interactivity does not survive mainstream retail. Kindle in particular will not render the widgets, video and interactive assessments that justify using Kotobee at all, so a book built this way is designed for a controlled channel and degrades badly if you later decide to sell it through ordinary retailers. There is also no print workflow: this is a screen-first tool, and anyone needing a paperback interior needs different software. Publishing native apps means holding Apple and Google developer accounts and passing store review yourself, which is a recurring administrative burden the software does not remove.
The honest half
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Kotobee.
Cross-shopped
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Each answer names the page it came from, so you can check it rather than take our word for it.
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.
No. It generates the application; you supply the developer accounts and go through Apple and Google review yourself, including every subsequent update.
No. It is built for education, training and reference material where interactivity and controlled access are the point.

Softwr does not host reviews and shows no star rating for Kotobee, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
