Hi HN!

After years of switching between separate apps for tasks, notes, files, calendar, and chat, I realized the problem isn't missing features—it's that productivity tools are built from incompatible primitives. Pages, folders, projects, and channels stay fragmented even when bundled together.

Cuadds uses one universal element: the cuadd. It can be a task, note, file, link, project, or anything. Because there's only one primitive:

    Everything can contain anything – no folder/file distinction. Every cuadd is both.

    Every cuadd is a workspace – invite collaborators at any level, not just top-level projects

    Every cuadd has its own chat – conversations attach to the exact item instead of messy general channels

    Calendar lives on top of your work – click any cuadd to schedule it. No separate calendar app.

You can nest infinitely, organize spatially (videogame-inspired UX), and daily execution actually works because scheduling isn't divorced from the work.

Would love feedback on the core concept.
