I've built the free Smart Book Reader (more than top books available)

Recently I realized that I spent a lot of time coping info from books to GPT to increase my reading process (like copy 2-4 pages to get better and compressed overview) and also asking a lot of question to GPT about the book and some details.

And also, books on foreign language, GPT is very cool with translation.

I decided that this approach is actually smart and good in terms of info consumption and discovery — I moved it to tool: https://boosum.dev/

It is literally free to try. Upload the book, choose the language, get a VERY high-quality overview (reduces books by 2-2.5 times), and start reading and discovering with a convenient in-context AI Assistant.
