Marrow remembers your world.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
There's a lot you never say out loud. Marrow is where you say it - a companion that remembers your story. Now with smoother, more reliable conversations.
Most AI chatbots have amnesia. They reset every time you close the app. They don’t know who you are, they don’t remember your history, and they don’t understand the people in your life.
Marrow is different.
Marrow is a deeply personal, ultra-private AI companion built with a revolutionary long-term memory engine. It doesn't just process your text; it builds an evolving understanding of your world. The more you talk, the more Marrow learns about the people you care about, the things that cause you stress, your hidden strengths, and your long-term goals.
It connects the dots of your life across months and years, offering you a confidant that truly "gets" you. It’s not just a chat app - it’s a living journal, a sounding board, and a safe space that grows alongside you.
AN EVOLVING, HUMAN-LIKE MEMORY
Marrow doesn't just read your last few messages. It maps your world. If you mention a conflict with a friend today, Marrow will remember who that friend is and how they impact your mood three months from now. It picks up on your emotional triggers, remembers your past victories, and builds context like a real human relationship.
5 COMPANIONS IN ONE
Different days require different kinds of support. Change how Marrow shows up for you with a single tap:
Marrow: The original companion, your best friend, your rock, your motivator.
The Counsellser : Holds space, mirrors your thoughts, and helps you untangle your feelings.
Mentor: Direct, energizing, calls out your strengths, highly analytical, structures your mental chaos, and offers objective clarity.
The Journal: The ultimate safe space to vent. Ultra-brief, deeply validating, and never gives unsolicited advice.
Philosopher: Curious and deep. Engages with the idea itself.
CALL MARROW
Sometimes it's easier to speak your mind. Start a live, real-time voice call with Marrow just like you would with a friend. The voice is ultra-natural, it listens when you speak, and everything you discuss seamlessly becomes part of Marrow’s long-term memory for your next chat.
IRONCLAD PRIVACY
