Show HN: A productivity app with reminders and nested AI chats (listal.space)

I built this app as a hobby project to experiment with developing a full-stack product from scratch—handling everything from the core utility and vision to the actual implementation. It took me about three months to build, and it was a massive learning experience that has prepared me to tackle my next set of projects.

What it does: The app allows you to create documents, whiteboards, and databases integrated with reminders and nested, agentic AI chats.

The "Beta" Reality: To be completely honest, the app is still quite "broken" in several areas. You might run into loading issues, UX friction, or bugs that could interrupt your workflow. I wouldn't recommend using this for mission-critical work yet; please treat it as a live demo or a functional prototype.

About the Subscription: You’ll see a payment option with certain limits. Honestly, I don't recommend paying for it right now given the current state of the app. If you do choose to subscribe, please consider it a donation to support further development rather than a purchase for a polished service.

Feedback & Collaboration: I have a lot of ideas for where to take this next and I plan on iterating quickly. I’d love to get your feedback on the concept, and if anyone is interested in collaborating or just chatting about the tech, I’m all ears.
