Rosmaryn is a web application that generates Human Design charts, known as Body Graphs. The tool calculates a user's chart based on their date, time, and location of birth. It determines the positions of the planets at the moment of birth to create a personalized energetic profile. The system integrates elements from astrology, the I Ching, Kabbalah, and the chakra system. The service is provided free of charge and does not require user registration, with chart generation taking approximately thirty seconds. The generated Body Graph displays a user's Type, Profile, Authority, and Definition. It also maps the specific Centers, Channels, and Gates that are active in the chart. Rosmaryn provides explanations for the five Types, five Strategies, different Authorities, Definitions, and the twelve Profiles. The tool distinguishes between conscious and unconscious aspects of the design. Additional resources include sections on the fundamentals of Human Design, its founder Ra Uru Hu, and celebrity Body Graphs. The application also covers related topics such as numerology and Vedic astrology. The primary workflow involves a user entering their birth information into the tool. The application then calculates the exact planetary positions for that specific time and location. The accuracy of the chart depends on the precision of the birth time, as a difference of one hour can activate different channels. The resulting analysis is intended to provide insight into a person's natural functioning, decision-making strategies, and how their energy interacts with others. The tool serves as an entry point for those exploring the Human Design system.
