Store listing
By Nils Rohwer, from the App StoreDescription by Nils Rohwer Written by the developer, not by AppBrain. Click to read.
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.
