Your Intelligence.
Entirely Yours.
Ghost is the AI that lives on your device — not on someone else's server. Instant responses. Perfect memory. Voice conversation. Absolute privacy. No cloud. No accounts. No compromises.
The Problem
Cloud AI trades your privacy for convenience.
Every message to cloud AI trains someone else's product. Your private thoughts, ideas, and conversations become their training data.
Your data feeds their models
Every interaction is logged, analyzed, and used to improve products you don't own.
Latency depends on their servers
Underground, on a plane, in rural areas — cloud AI gives you nothing.
One breach exposes everything
Centralized services are honeypots. One breach, millions of private conversations leak.
The Solution
Ghost runs where you are
A 3-billion-parameter intelligence engine on your phone. No internet required. No data leaves. Ever.
Core Systems
Six capabilities. One agent.
Everything you need from an AI assistant — nothing you don't. All running entirely on your device.
Persistent Memory
Remembers facts, preferences, events, and relationships across sessions. Importance-based decay, contradiction resolution, and user-controlled deletion. Encrypted SQLite + FTS5 + vector embeddings.
Comparison
Cloud AI vs Ghost
The most protocol-complete agent
Ghost implements all 8 major agentic AI protocols — ready for the multi-agent future where AI systems discover, negotiate, and collaborate autonomously.
MCP
Expose tools & resources to LLMs
A2A
Inter-agent discovery & delegation
ANP
Cross-system mesh networking
AG-UI
Real-time streaming (SSE/WS)
AGORA
NL-driven multi-agent orchestration
LMOS
Transport-agnostic meta-protocol
AP2
Autonomous agent transactions
OASF
Agent skill & cost discovery
Performance
Faster than cloud AI
No network round-trips. No queue wait times. No throttling. Ghost responds at the speed of your hardware.
Speculative Decoding: 3B Quality at 0.6B Speed
A tiny 0.6B model generates candidate tokens at 80-100 tok/s, predicting what the larger model would say.
The 3B Workhorse checks all draft tokens in a single forward pass, accepting correct predictions instantly.
Result: the reasoning quality of a 3B model at nearly the speed of a 0.6B. An engineering breakthrough.
Privacy
Privacy isn't a feature. It's the architecture.
Most AI companies promise privacy through policy. Ghost delivers it through engineering. There is no server to breach. No account to hack. No data to subpoena.
Security Architecture
No server to breach. No account to hack. No data to subpoena. Your intelligence lives on your device.
