Build habits that stick, coached by history's greatest philosophers. Marcus AI is a habit tracker where Marcus Aurelius, Socrates, and six more don't just talk: they propose habits, refine them, and log your check-ins, always with your confirmation. Check in, keep your streaks alive, and let reminders carry you through the day. And when a habit needs more than a checkbox (motivation, a plan, an honest look at why it keeps slipping), open a chat and reason it out with a philosopher, by typing or speaking. EIGHT PHILOSOPHERS, ONE GOAL Marcus Aurelius, Socrates, Aristotle, Epictetus, Seneca, Confucius, Siddhartha Gautama, and René Descartes, each with their own voice and method. Stoic discipline, Socratic questioning, Aristotelian balance: pick the mind that fits the habit you're building.
