Start every morning with full context
Aion delivers a personalised briefing each morning — your calendar for the day, active reminders, and a digest of what's changed in your world. Set your preferred time once. It arrives every day, even when the app is closed.
Built on what Aion actually knows about you. Not a generic summary — your day, your context.
A belief system, not a chat log
Aion doesn't just remember what you said — it extracts structured facts, tracks confidence, and updates its model as your world changes.
Confidence tracking
Every fact has a confidence score. Consistent mentions raise it. Contradictions lower it. Stale facts decay. Aion knows what it's certain about.
Contradiction detection
When new information conflicts with what's stored, Aion flags it, weighs the evidence, and updates accordingly. Never two conflicting beliefs held silently.
Temporal recall
Ask "what did I tell you last month?" and Aion pulls from timestamped belief history. Every fact carries when it was learned and when it changed.

How Aion learns
Every conversation teaches Aion something. It runs 121 extraction rules across your messages, pulling structured facts into a confidence-weighted belief store. It tracks changes, detects contradictions, and decays stale beliefs over time.
Ask "what do you know about me?" at any time to see your full memory profile.
Optional local runtime
For users who want a fully offline setup, Aion includes an optional local model tier backed by a quantized GGUF model running natively on your device. No internet required.
Local mode handles everyday queries and tool calls without any network dependency.
