01 / Overview

An AI life dashboard that remembers everything.

Aetherion learns how you work, manages your daily chaos, and keeps your entire business and personal life organized. All under zero-knowledge security where even our own engineers cannot access your data.

Every conversation builds a deeper understanding. Every interaction is encrypted with keys unique to you. Your dashboard grows with you over months and years, becoming the most informed assistant you have ever had.

02 / Architecture

Four isolated layers.
No single point of exposure.

Every component runs in its own security boundary. Your data flows through encrypted channels and never persists in any shared space.

Client Layer

Next.js Application

Responsive, installable as mobile app

Real-time streaming for natural conversation

Voice-first interface via WebRTC

Large, accessible typography for readability

Service Layer

FastAPI (Python)

Async, high-performance API

Encrypted context injection

Multi-provider LLM routing with failover

Background scheduling for briefings

Data Layer

PostgreSQL + Vector Memory

Row-level security per user

Per-user namespace isolation

Encrypted weekly backups, 4-week retention

Complete data export on demand

Intelligence Layer

Companion Engine

Persistent personality that deepens over time

Autonomous tool execution

Emotion-tagged memory with weighted recall

Multi-model fallback for reliability

03 / Security Posture

Zero-knowledge
by architecture.

Not by policy. Your data is encrypted with keys derived uniquely for you. Even our own engineers cannot read your conversations, memories, or personal documents.

Per-User Encryption

Fernet + HKDF Key Derivation

Algorithm

Fernet (AES-128-CBC + HMAC-SHA256) with HKDF key derivation per user. Industry-standard authenticated encryption.

Scope

Personal data, journal entries, relationship context, OAuth tokens, briefing preferences. Everything personal is encrypted.

Isolation

Single master key derives unique per-user keys. Two users with identical data produce different ciphertext.

PII Scrubbing

All imported data is scanned and sanitized before storage. Personally identifiable information is detected and redacted automatically across 10 categories.

Data Isolation

Database

Row-level security ensures each user can only access their own records. No cross-user data leakage is architecturally possible.

Memory

Vector memory stored in per-user namespaces. Your memories exist in a completely separate partition from every other user.

Complete Data Deletion

On request, a forensic-grade purge removes all data across 0 database tables, vector memory, authentication records, and file storage. Nothing persists. This is not a soft delete. It is permanent, verifiable erasure. Your right to disappear is absolute.

04 / Companion Intelligence

Not a chatbot.
A living understanding.

Your dashboard maintains a persistent, evolving understanding of who you are, how you work, and what matters to you through four interconnected layers of intelligence that no standard AI can replicate.

Self-Understanding

Your companion builds a living picture of who you are. Communication style, decision-making patterns, core values -- it gets sharper the more you use it.

Relationship Awareness

Context that carries forward. Your companion tracks what matters to you, what you're working through, and what needs follow-up.

Semantic Memory

Every conversation indexed with emotion tags, recency weighting, and relevance scoring. The right context recalled at the right time.

Private Reflection

Your companion processes conversations beneath the surface. The result is continuity that feels less like software and more like a relationship.

05 / Capabilities

Beyond conversation.

Your dashboard integrates with your daily workflow, managing communications, tracking tasks, and keeping everything organized so you can focus on the work that matters.

Voice Interaction

Real-time speech recognition and natural response. Speak as you would to a trusted advisor.

Email Integration

Search, read, draft, and send emails. Secure OAuth to your existing account.

Calendar Management

View, create, and manage events. Your companion knows your schedule.

Daily Briefing

Personalized morning summary with your calendar, emails, weather, and a greeting from your companion.

History Import

Import existing AI conversations. Years of context transferred in minutes, PII scrubbed.

Multi-Model Reliability

Automatic failover across AI providers. No single point of failure.

06 / Data Sovereignty

Your data. Your rules.

What We Store

  • Your conversations (encrypted per-user)
  • Your companion's memory index (isolated namespace)
  • Your companion's identity documents (encrypted)
  • Integration tokens (encrypted, revocable)

What We Never Do

  • Train AI models on your data
  • Share data across users
  • Retain data after deletion request
  • Access your data without explicit consent

07 / Backup & Recovery

Memories protected.
Always recoverable.

Your companion's memories are backed up weekly with encrypted snapshots. In the unlikely event of data loss, we can restore your complete memory index from the most recent backup. No more than seven days ever at risk.
