From the developer:
SBook®5 is an extremely fast, AI-based personal information manager. Information is organized in free-format entries --- one for each person or company. Each entry can have any number of postal addresses, phone numbers, email addresses, photographs, URLs, and other information.
SBook5 automatically tells the difference between an entry that represents a person and one that represents a corporation, and sorts accordingly.
You may want to check out more software for Mac, such as Budget Planner, To be Artist or AddressBook Aid, which might be similar to SBook5.
