About this app

There's a lot you carry around that you never say out loud. Marrow is the place to say it.

Marrow is a private AI companion that builds a genuine memory of who you are — your patterns, your relationships, your emotions, what you're working through. Not just today's conversation. All of it, over time.

A COMPANION WITH REAL MEMORY
Most AI forgets you the moment you close the app. Marrow doesn't. Every conversation deepens what it knows about you. Come back days later and pick up exactly where you left off — Marrow already knows the context.

FIVE COMPANION STYLES — SWITCH ANY TIME
Choose the kind of support you need right now:

❤️ Marrow — warm, attentive, genuinely curious about you
🧭 Counsellor — reflective, emotionally attuned, holds space without judgement
🧗 Mentor — helps you think it through, then move on what matters
📔 Your Journal — ultra-brief, just validates; holds what you need to get out
🦉 Philosopher — curious and deep, engages with ideas on their own terms

Your memory is shared across all styles. Switch freely.

TALK, TYPE, OR CALL
Send a voice note. Type a message. Or start a Live call and speak naturally — Marrow listens and responds in real time, with full voice, like a phone call. Your companion remembers every exchange however it arrives.

PRIVATE BY DESIGN
Marrow runs on a paid-tier AI service that contractually does not train on your data. Your conversations are stored only on our servers and are fully deletable — permanently, at any time, in one tap.

AVAILABLE IN 7 LANGUAGES
English · Deutsch · Español · Français · Italiano · Nederlands · Português
