Hi Product Hunt! 👋

I’m the founder of Activity Category Insights (ACI).

After years of working with IT projects, meetings, emails, and deadlines, I kept coming back to one question:

Where does my working time actually go?

The information was already there — scattered across Outlook, Gmail, and calendar appointments — but turning it into a meaningful overview wasn’t easy.

That’s why I built ACI.

Instead of tracking your screen or requiring you to start and stop timers, ACI analyzes your existing email and calendar activity to reveal:

📊 Meeting and workload patterns
📧 Communication activity
📅 How your working time is distributed
⏱️ Insights that can help prepare timesheets
📈 Trends across your activities

Privacy was important from the beginning. ACI processes connected activity data locally on your computer.

It’s available for Windows and macOS, with a fully functional 7-day free trial and no credit card required.

I’d really appreciate your feedback:

Would this approach help you understand your working time better? And what insights would you find most useful?

Thanks for checking it out!
