subika-04/LifeVault ? reverse-engineered prompt

Build me a personal life organizer app called LifeVault.

I want a modern dark themed web app where someone can keep track of their important documents, expenses, assets, and reminders all in one place. It should feel like a polished productivity dashboard, with a clean sidebar, summary cards, charts for spending, and pages for documents, assets, expenses, reminders, and a timeline view.

Please make it full stack, with user login, a database, file upload support, and a backend API that can save and search everything. I also want an AI assistant that can look at the user’s saved data and help explain documents, pull out useful details, and answer questions in a grounded way using the user’s own information. If you need to check current docs or APIs while building, go ahead and look them up online.

Use a responsive layout, smooth empty states, and a professional SaaS style so it feels ready for a demo or portfolio project.
