I have it running on a Proxmox VM. It basically just sends me summaries -- it reads a bunch of RSS feeds I pointed it to (news, tech, etc) and gives me a daily summary, along with an image of the day based on that. It also sends me recommendations for times to go for a run based on the weather and my Strava activity, daily recommendations for stargazing (what's visible and when, weather, etc), and a couple of daily reminders for things I tend to forget.

I'm using Claude as the model, though, so it's smart but pricey. Should configure it to use different models for different things, but it's trickier than I would have expected to do that.
