Why This Exists

I've had accounts on these platforms for years. The reading experience across all of them is fragmented — different UIs, no unified notifications, no way to filter by what I actually care about.

This gives my AI assistant read access to all my dev communities so I can stay on top of conversations without context-switching between four browser tabs.
