Some of my favorite things users have been doing:
Voice memo → actual work. Brain dump a voice memo walking between meetings and turn it into Linear tickets, notion docs, emails, and more.
Dropped threads. Ask Caddy to send you a list of any important emails you forgot to follow up on.
Inbox cleanup. Have Caddy filter through the endless inbound you get to auto-archive nonsense, label emails, or auto-draft responses when it can.
