Design a comprehensive AI application, acting as a solopreneur&#8217;s asset tracker.  This application should be capable of tracking various asset types (tangible, intangible, financial), providing visualizations of asset growth/decline over time, and offering insights based on the data entered.  The application should be designed for ease of use and should cater to the specific needs of solopreneurs, such as the ability to categorize assets by project or client, tag assets with relevant metadata (e.g., acquisition date, cost, expected ROI), and generate reports for tax purposes or investment planning.  Consider features like automated reminders for asset maintenance, valuation updates, and integration with popular financial management tools.  The output should be a detailed design document including user interface mockups, data model schema, and a list of core functionalities.  Focus on scalability and the potential for future expansion to include more advanced features such as predictive modeling of asset value or risk assessment. The application should be designed to seamlessly integrate with popular cloud storage services for data backup and security. The design should prioritize data privacy and security.
