Introducing Nellie 3.0: The highest quality bestselling book generation model yet

I love their stories they’re so fun and cozy, like you’re just hanging out with a friend who happens to tell the best tales ever. Totally recommend if you want a little happiness in your day.

Izzy

That's crazy and kind of scary

Heath

I really didn't think it would be able to generate mangas like that. The art actually looks like it was drawn by a studio and goes exactly with what's written on the page.

Kori Patterson

Used it to write up investing & economics courses. Actually gets the info right & is really up to date, lays out the course perfectly like a teacher walking you through a class.

Grant Hughes

Makes great books for me to read at night before going to bed. It's like a private author all to yourself.

Camilia

I use it to write relaxing books. I really like the art style and depth it gives the characters.

Livia

Weaves together engaging storytelling with deep insight, creating a story that is both thought-provoking and inspiring. Their words stay with you long after you turn the last page. 🙂

Stephanie

I read a lot of books and this really fills an empty spot in the shelf for me. Any time I have an idea or a thought for a book I throw it into it and am seriously impressed by the results. I could use this thing all day.

Kaitlyn Garcia

Makes complex ideas clear and practical. Their textbooks don’t just sit on my phone, they actually get used by my friends, and I trust them as go-to resources.

Felix Becker

It writes great books that have surprisingly interesting plots, it made me question who's writing it at first because it really sounds like a real person!
