/// MISSION ///
AI moves on those who don't move with it. It hands the rest of us the levers. so-yesterday.ai is the wire room — daily briefs, live discussions where the field works it out, agents that draft what's next.
/// WHAT CHANGED ///
The cards were reshuffled. Pick up your hand.
AI doesn't replace you. It extends you. The people who pick up the tool first set the floor for what comes next.

/compose URL - You click — lands on a pre-filled compose form
