I’ve built https://manor.app with the intention of it fitting the “user-friendly mass-market interface” you suggest. It’s essentially a “second brain” app for your home(s), covering inventory, documents, tasks/reminders, notes, etc. The inspiration is tools like Asana, Linear, etc I used in my career as a software engineer, tailored for the home.

It’s my sole area of focus, with more document retrieval and analysis (and UI polish) on the way.
