Is this generator providing legal advice?

No. The Front Matter generator produces conventionally formatted publishing pages — the copyright page, disclaimers, and front matter that appear in a typical book. It is not legal advice, and using it doesn't create a lawyer–client relationship.

For most self-published fiction and nonfiction, standard pages are all you need. But if your book involves co-authors, an estate, licensed or quoted material, song lyrics, trademarks, or other complex rights questions, have a qualified attorney review it. The generator gives you a correct-looking starting point, not a legal opinion.
