Question 1

How is Lex different from Project Gutenberg for reading _ Instaread?

Accepted Answer

Lex sources public domain books from Project Gutenberg, Standard Ebooks, and the Internet Archive, but adds a modern reader (custom fonts, themes, highlights, bookmarks, dark mode), human-narrated audiobooks for the major works, native iOS and Android apps, and reading progress sync across devices. Project Gutenberg provides the raw EPUB files; Lex turns them into a reading experience.

Is Lex free?

Accepted Answer

Yes, Lex is free to use for all public domain books and audiobooks, including every _ Instaread title. No signup is required to read or listen. A premium tier exists for AI features and exclusive originals, but the entire public domain catalog is free forever.
