After years of wrestling with state management, I've found myself excited by how Convex queries have simplified the way I think about derived state. Instead of juggling complex state libraries and websocket implementations, Convex offers a refreshingly straightforward approach: just declare what data you need, and it stays synchronized across all clients automatically. It's made me wonder if we've been overcomplicating things all along.

I recently built a full-stack app called notesGPT. It allows you to record a voice note, transcribes it, and extract action items and display them as action items. It’s fully open source and comes equipped with authentication, storage, vector search, action items, and is fully responsive on mobile for ease of use.
