How I plan to use AI to find a nanny share

I’m still early enough in my first trimester that I “shouldn’t” even be talking about the baby, but I’m already thinking about childcare. (I’ve taken Reddit’s advice.)

After doing some research, my husband and I decided we’d like to find a nanny share for the first ~year, then switch to a daycare.

Facebook’s upside… and flaw

How do you find a nanny share in 2025? The consensus from asking friends is: Facebook groups.

So I promptly joined a half-dozen parenting and newborn-adjacent Facebook groups in my area. Indeed, I saw a steady stream of people either posting to offer nanny services, or to seek nanny shares. Amazing!

But, my Facebook notifications immediately started to get noisy:

my Facebook group notifications showing lots of posts from the parenting groups

Most of these posts also aren’t useful to me, because they aren’t about nanny shares or don’t match my start date. And unfortunately, these are my only options for when to get notified:

The notification setting I want Facebook to build is: “posts relevant to what I want from this group,” with a text box that lets me type in what I want (“posts about nanny shares within a ~15 minute drive of my city with a start date in fall or winter 2025”).

I’m sure that someday Facebook might add this feature, using AI behind the scenes. But that day is not today.

What would a tool look like?

At a high level, LLMs (Large Language Models) are an appropriate tool to help filter the signal from the noise in these groups, because:

The shape of this problem is one that LLMs are very good at solving: Look through a lot of text, and flag any text that aligns with a set of criteria (which are also written out as text).
Mistakes aren’t a big deal. If I miss a post I should have seen, or look at a post that’s not relevant to me, it’s a minor inconvenience.

In theory, if I could create a robot that periodically looks through each Facebook group, and copy/pastes the new posts into a “ChatGPT”-like tool, and asks that ChatGPT tool “which posts are the ones Jess is interested in? (here are the criteria)”… that would be great!

So, that’s the challenge. And the plan for tomorrow!
