Cortex
Perception
The outer sheet. Reads what you give Aurora — text, images, voice, files — and turns it into structured signals the rest of the brain can use.

A mind shaped by the
one inside your head.
Aurora's brain isn't an abstract graph. It is modelled, region by region, on the human brain that built it. Cortex perceives. Hippocampus consolidates. Amygdala weighs what matters. Cerebellum predicts. They fire in concert, on your device, in milliseconds.

Anatomy
Six regions, one mind.
Hippocampus
Consolidation
Where short-term experience becomes long-term memory. Replays the day overnight and writes the lasting traces into cortical storage.
Amygdala
Salience
Tags every memory with how much it matters. What was emotionally heavy gets a brighter coat — and surfaces faster when you reach for it later.
Cerebellum
Prediction
The pattern engine. Learns the shape of your habits, days, and people, and predicts what's next so the rest of Aurora can act before being asked.
Temporal lobe
Recognition
Faces, names, voices, places. The region that knows who and where. Wired directly into the hippocampus so context arrives with identity.
Default mode
Quiet thought
The network that fires when nothing is asked. Aurora's idle mind wanders through memory, surfaces connections, and prepares the answers you haven't asked yet.
How it learns
The same three laws your brain uses.
Hebbian plasticity
Neurons that fire together, wire together. Two memories activated in close succession grow a stronger synapse — the next thought of one summons the other.
Δw ∝ pre·postHippocampal replay
While you sleep, your hippocampus replays the day's experiences at 20× speed, writing them into cortex. Aurora does the same, on a slower clock.
replay rate ≈ 20×Synaptic decay
Unused connections weaken. The brain doesn't store everything forever — it lets unimportant signals fade so the important ones stay legible.

What lives in the Nexus.
Conversations
Every exchange you have with Aurora becomes a memory. Threads can be replayed, branched, or merged.
nodes · context: chatDocuments
PDFs, notes, transcripts — Aurora reads them, splits them into idea nodes, and connects them to existing memory.
nodes · context: docPeople
Names you mention, faces in your photos, voices in your meetings. People become hubs that anchor everything around them.
nodes · context: personPlaces
Cities, rooms, paths you walked. Geographic memory is just another shape of node — it weaves through everything.
nodes · context: placeDecisions
Aurora keeps a quiet ledger of choices, the options you considered, and what came of them. Looking back is one query away.
nodes · context: decisionFeelings
Notes about mood, energy, friction. Optional and private. They give Aurora the context to know when to speak and when to stay quiet.

Three minutes to set up. Aurora begins quiet — it earns its place as you give it things to remember.
