It actually works! I've found Google Alerts to be extremely noisy and alert me for content about certain people.
Alias only notifies you if the person actually participated/appeared on it vs. being covered.
We're also deeply indexing folks and their content so you'll be able to do conditional alerts.
Example: "Notify only me when Elon talks about battery prices" or "Notify me when Stéphane Bancel (Moderna CEO) talks about Delta Variant".
Hope that makes sense!
