Show HN: Classic philosophy books made easy using AI

I like reading old books, but I often struggle with them because of the archaic language they use. I thought that LLMs might be a way to improve this, so I started working on AItheneum. It's a library of classic philosophy books enhanced with LLMs.

So far it has three features:

- Reading level: It displays the original text alongside two simplified versions ("medium" and "easy" levels).

- Explain: Highlight a section of the text, and you can ask it to explain that extract for you.

- Search: Search for specific themes within the book (e.g., "religion," "purpose of life") and get relevant sections highlighted.

I've only added the First part of Thus Spoke Zarathustra, and I'm working on adding more sections of it and more books. But I thought others might find it interesting as it is right now.

Some of the translations and explanations are not that accurate, and the search feature is a bit confusing. But I'm working on it, and I'd love to hear your feedback.
