An excellent tool that significantly simplifies the work
It's an excellent tool that significantly simplifies the work of a self-publisher, especially when it comes to a novice or someone with less experience, but also for those who are competent in other areas and find the research phase more complex. The overview offered and the suggestions provided represent a solid foundation from which to start building the business.

PubliShark.AI left me speechless! It's everything you need
PubliShark.AI left me speechless! It's everything... everything you need and that was objectively missing! Simple, intuitive, perfectly effective and clear... very pleasant interface, fast, fluid and clear... I really enjoyed using it, interest, enthusiasm and surprise... desire to keep reading! I was very tired at the end of the day and despite this I found the results engaging, simple and clear! I'm one of those people who go into overload in front of too much data, noisy interfaces and redundant content... I also really appreciated the fact that all the results were explained exhaustively and effectively, in a way suitable for any level of publisher.
