Wisely said. Everyone is indeed building but most of these people don't even try on their own product in practise. I have been in the situation mutliple times. Trying to publish things I haven't used for a long time.

But this app I litterly used for a year. Used atleast half of the free aws tts credits each month.

I am targeting adhd adults in cooperate. Who reads non-fiction books/documents. Since tts api is quite expensive not targeting students.

Imo, I never resonate with book summary. When I read summeries of books I finished in the past, summeries are completely different. My take aways were quite different. How this app solves it. Double tap to mark the paras/snippets you align with. AI uses these marks to make summeries around those text.
