What it does
Notebooks is a writing and organization app that stores notes, documents, and files in nested books. The official site describes it as a text and Markdown editor with personal-wiki and Zettelkasten uses, and says books and documents can become projects and tasks. It is best considered by people who want notes, longer writing, and related files kept in one structured collection.
A writer could create a book for a research topic, put short source notes beside a longer draft, and use nested books to divide the material into themes. Notebooks' official page describes this kind of nested structure and emphasizes keeping documents and files together. It also says documents can become tasks and books can become projects, so the tool can extend from note capture into lightweight planning.
The product is available for iPhone/iPad, Mac, and PC according to its homepage; it is sold as a one-time purchase rather than a subscription. Before selecting it for collaboration, check the documentation for current sync and sharing details: the product page emphasizes personal organization, and this research did not test team workflows or device sync.
