nexo

NEXO transforms Claude Code from a stateless assistant into a cognitive partner that remembers, learns, forgets, adapts, and builds a relationship with you over time.

Every time you close a Claude Code session, everything is lost. Your assistant doesn't remember yesterday's decisions, repeats the same mistakes, and starts from zero. NEXO fixes this by giving Claude Code a brain — modeled after how human memory actually works.

Claude Code is powerful but amnesic:

• No memory — closes a session, forgets everything
• Repeats mistakes — makes the same error you corrected yesterday
• No context — can't connect today's work with last week's decisions
• Reactive — waits for instructions instead of anticipating needs
• No learning — doesn't improve from experience

NEXO implements the Atkinson-Shiffrin memory model from cognitive psychology (1968) — the same model that explains how human memory works:

What you say and do
    │
    ├─→ Sensory Register (raw capture, 48h)
    │       │
    │       └─→ Attention filter: "Is this worth remembering?"
    │               │
    │               ↓
    ├─→ Short-Term Memory (7-day half-life)
    │       │
    │       ├─→ Used often? → Consolidate to Long-Term Memory
    │       └─→ Not accessed? → Gradually forgotten
    │
    └─→ Long-Term Memory (60-day half-life)
            │
            ├─→ Active: instantly searchable by meaning
            ├─→ Dormant: faded but recoverable ("oh right, I remember now!")
            └─→ Near-duplicates auto-merged to prevent clutter

This isn't a metaphor. NEXO literally implements Ebbinghaus forgetting curves, rehearsal-based reinforcement, and memory consolidation during automated "sleep" processes.
