First conversation

After install, your agent sets the project up with you. It starts here:

Capture the shape of the user's life — their areas of focus, current goals, active projects, key people, and what they're reading or learning — so the second brain starts grounded in who they actually are.

  • “What are the main areas of your life you want to keep on top of?”
  • “What are you working toward right now — any goals or projects in motion?”
  • “Who are the people that matter most, and what are you reading these days?”
