I use Perplexity to research a few topics that change regularly, and I’m wondering if there’s a way to follow them rather than rerun the same search every week. Can it notify me when new sources or developments show up for a query?

I’m not looking for a general news feed; ideally, I could keep an eye on a focused subject and review what has changed since my last check. Does Perplexity support that kind of monitoring, or do people handle it another way?
