A little companion.
A lot off your mind.

Give Mellow a responsibility, the context it needs and clear boundaries. Your agents can work through tasks and configured routines—bringing back results and surfacing the decisions that need you.

Give it context. Leave it a responsibility.

Routine work can move without another prompt. Set the scope once, then hear about results, exceptions and useful changes.

The brief is ready before you think to ask.

A configured routine brings the new brief and prior notes together, so the next meeting starts with the changes and open questions.

Your meeting brief is ready.

  • What changed since the last draft
  • Decisions still open
  • Questions worth asking

Prepare a private brief. Sending it to attendees or changing an event is a separate action.

Illustrative workflow · Requires configured files, agent and schedule. All examples use sample data.
