This could be a useful tool for non native speakers. It’s not always easy to understand figurative speak in a foreign language for example. It doesn’t replace the original book. Books shouldn’t be gatekept.

I checked out Ulysses by James Joyce and it just says

"Had brekkie, bit of a walk, wanked off on the beach, got bladdered with a bunch of prozzies while me wife cucked me and back home in time for brekkie again"

I love when they invent new problems to sell you the solution.

I would have used the hell out of this in high school for those boring books I don't remember anything about anymore

I might actually do this for Moby Dick. Fuck Melville's writing.

"He must have looked up at the sky - which was kinda different - and then admired his new lawn."

If it actually has quality output this could be great for jargon filled non fiction works that are impenetrably dense for people outside of the field, like in law or science.

Didn't J.K. Rowling do this with Harry Potter? She wrote the first book with simple words and slowly upped the difficulty every installment. Being a teacher for developmentally disabled kids, she knew that some of the books they were being forced to read were like throwing new swimmers into the deepend.
