Huh. So I've never taken meeting notes. I guess you write down some things people said. Do you then refer back to that later, or is it a memory aid thing? I don't feel like I'm missing anything, but equally the op has built a product to automate this, so it's got to be important in some contexts. Would like to know what I'm missing
1. Decisions and supporting details
2. Action items with dates and assignees
Those should be sent out to all attendees of the meeting (or written in a place that's accessible to everyone). Beyond that, each person needs to take notes for themselves for other things they want to remember.
