Startup Idea: Priority-Based Notification Manager

Startup idea to develop a software that serves as a hub for all notifications across multiple platforms. This software would rank notifications based on urgency, priority, learned behavior, and user-defined criteria, deliver top-priority notifications instantly, and give periodic summaries of the rest.

I am a graphic and web designer at a large organization, and I also volunteer as part of some design and creative groups.

There are multiple ways that we communicate and collaborate online: social media groups, slack, group messages (imessage), e-mail. I get way too many notifications. The notification settings for these platforms really cannot be dialed in enough.

I want some software that ALL my notifications like this will be funneled to first, before I see anything. This software would have built in algorithms to detect urgency/priority/importance of the notification, and it would also learn from how I respond to them. I would ideally also be able to enter certain keywords, senders, etc, that get assigned higher priority. I would get most important notifications right away. After that I could receive periodic summaries of the rest (and I could set how often I would receive those summaries).

Also, this software would have the option to remind you about each notification later, to a specific duration you choose. And a snooze all notifications option as well.

Would be most useful to me on an iPhone if possible, or if not, on my Mac.

Thanks!.
