How we use neuroscience to organize your memories like your brain does
Every memory is stored in the brain region where it naturally belongs, using the Montreal Neurological Institute coordinate system - the global standard for brain mapping.
MNI coordinates are like GPS for your brain. Just as every location on Earth has latitude and longitude, every brain region has a 3D coordinate (X, Y, Z). Scientists use this system globally to precisely locate brain structures.
When you share a memory, Polarity analyzes its content and stores it in the appropriate brain region. A childhood memory goes to the Hippocampus. An emotional experience goes to the Amygdala. This creates a scientifically-accurate map of your mind.

Understanding the core concepts that power your memory
A Memory in Polarity is any piece of information you share or experience: a thought you express, a conversation you have, a task you need to complete, a feeling you want to process. Each memory is timestamped to the exact moment, categorized by the brain region it belongs to based on MNI coordinates, and connected to related memories in your knowledge graph. Memories are the raw building blocks of your vault - every moment captured and preserved exactly as it happened.
Knowledge is the synthesis and understanding that emerges from your memories over time. When patterns emerge across conversations, Polarity creates knowledge entries: facts about people you know, preferences you consistently show, lessons you have learned, and wisdom you have gained. Knowledge is persistent understanding that transcends individual moments - it is what you know to be true about yourself and your world. Unlike memories which capture moments, knowledge captures meaning.
Your Brain ID is your unique identifier within Polarity - a cryptographic key derived from your unique thinking patterns and interaction style. It is the only key that can unlock your vault. No email address, no password to forget, no security questions. Just a simple code that represents you. Your Brain ID ensures that your memories are yours alone - even Polarity cannot access your vault without it. It is both your identity and your encryption key, making your memory truly personal and secure.
The Polarity Calendar is not just a schedule - it is a time-aware companion that understands your life context. It automatically detects your timezone and location, learns your patterns and preferences, and helps you stay on top of commitments without the friction of traditional calendars. Events are linked to memories, so you can see the full context of every appointment. Recurring events, reminders, and important dates are all woven into your memory fabric, creating a seamless timeline of your life.
