Marcus: Stoic AI Mentor

Marcus: Stoic AI Mentor is a Stoic teacher that lives entirely on your iPhone. Ask anything, in your own words, and Marcus answers as a teacher of Stoic virtue: calm, direct, and practical. No feeds, no streaks, no noise. Just a quiet conversation whenever you need to think something through. WHAT MAKES IT DIFFERENT - Fully on-device. The conversation runs on Apple's on-device intelligence, so nothing you write ever leaves your iPhone. - Fully offline. It works in airplane mode, on a plane, or with no signal. - No account, ever. No sign-up, no email, no cloud profile. - No subscription. Download it and use it. TALK IT THROUGH Bring a worry, a decision, or a hard moment. Marcus helps you separate what is in your control from what is not, name the thought behind the feeling, and choose a measured response. Start from a blank line or tap a prompt like "Help me respond calmly" or "Untangle a worry." MEMENTO MORI MEDALLION A quiet daily reminder that your time is finite. Flip the medallion, sit with the thought, and let it sharpen how you spend today. BUILT TO BE CALM Warm, considered design with no ads and no data collection. Marcus AI is made to be opened, used, and put down again, so you can get back to living. Requires an iPhone with Apple Intelligence.
