Show HN: To To-Do – Collaborative Task Lists with AI and Dexie.js

Hi HN,

I couldn’t find a to-do app that worked the way I needed – cross-platform, offline-first, real-time collaboration – so I built one.

Key features: - iOS, Android and Web with seamless sync (Dexie.js + Dexie Cloud). - Real-time collaborative lists (great for families and teams). - AI assistant for generating tasks, recipes, or workout plans. - Rich text editor with attachments and notes.

I’ve been working on this for ~2 years (~2,500 hours of dev). My small team and family use it daily, and now I’d love HN’s feedback.
