## よくある質問

### Is SoBrief free to use?
Yes. SoBrief offers a large free catalogue of book summaries, and a free trial lets you explore the library. Paid tiers add conveniences such as expanded access, extra formats, and offline reading, but the site's pitch is built on free access to a broad summary library.

### What does a SoBrief summary actually contain?
Each title has a concise summary that captures the core ideas, themes, and key takeaways of the book, rather than a chapter-by-chapter recital. Length varies by edition, and summaries are refreshed over time, so you get the essence in a few minutes.

### Can I download summaries as PDF or EPUB and listen to audio versions?
Yes. Many summaries are available as downloadable PDF and EPUB files and as audio, so you can read offline or listen on the go. Format availability can vary by title and by plan.

### Does it cover fiction as well as nonfiction?
SoBrief catalogues both: most-read fiction such as Harry Potter, The Hunger Games, Fourth Wing, and Pride and Prejudice, alongside nonfiction like Atomic Habits, Sapiens, and Meditations. The homepage splits the catalogue into Fiction and Nonfiction sections and lets you browse by genre, author, and trending lists.
