The system is suit‐ able for mobile phones, with financial management functions as the starting point and simplified management operations as the pur‐ pose, and realizes a system that is mainly based on OCR recognition scanning and recording bookkeeping functions, supplemented by financial analysis functions of big language model, big data consumption classification trends, and multi-version switching of ver‐ sions suitable for people of different age groups. The system not only greatly improves the efficiency of people's bookkeeping, but also promotes the intelligent financial transformation of society.
