I built my own AI chief of staff. Here's what I learned.
Most business owners don't need more tools. They need fewer places to look.
So I built one app that pulls my day into one conversation. Her name is Donna.
What she does:
• Email: reads every inbox, puts real people ahead of the noise, and drafts two replies I can edit and send.
• Calls: searches my recorded client calls, so I can ask "what did I promise Dana last week?" and get an answer with the call and the date.
• The day: one view of who's waiting on me across email, Slack, our CRM and Basecamp.
• Voice: a live, two-way conversation. I can interrupt her and she stops and listens. Or I type, or I dictate.
The rule I built it on: Donna proposes, I commit. She can read almost everything, but she can't act alone. Every task, calendar block and email shows up as a card I approve. Software that guesses "done" is worse than a person who forgets, because nobody's there to catch it.
How it got built: my dev team was busy shipping client tool builds, and that work comes first. So I went solo on this one. It was me, a clear picture of what I wanted, and Claude Code doing the heavy lifting, one feature at a time. I still have to know why the code works before it ships. The AI multiplies a clear head. It doesn't replace one.
This is what we teach at Kean on Biz: simplify first, then automate what's left.
What's the one thing you'd hand to a Donna first?
