Every Feature. Every Proof.

Enterprise-grade AI capabilities and cryptographic accountability, in an app that fits in your pocket and works without internet.

AI Evidence Log

Cryptographic evidence, not claims.

Device-signed proof record for every AI action: model provenance, context fingerprint, processing locality
SHA-256 hash chain — any modification breaks the chain and is detectable
Signing keypair in Secure Enclave / Android Keystore — private key never leaves hardware
Three transparency modes: Simple, Advanced, Paranoid
Exported bundles are self-contained, independently verifiable evidence packages

Deterministic Replay

Reproduce any AI decision. Exactly.

Stores input, model version, context hash, random seed, output token hash
Model archive with append-only retention: 3–7+ years for regulated industries
Same execution-provider constraint plus token ID hashing — deterministic at integer level
Context compression (zstd, 3–5x) for long-term feasibility

Persistent Memory Graph

Remember what matters. Prove what was used.

Facts, preferences, events, relationships as structured graph
Importance decay: 5% weekly unaccessed, 2% frequently used
Multi-factor retrieval: semantic (40%) + recency (20%) + importance (25%) + frequency (15%)
Memory Value Index: reference frequency, staleness, redundancy, density scores
Every memory reference logged in proof records

Voice Conversation

Tap. Speak. Listen. All offline.

On-device Whisper STT — no cloud speech APIs
Streaming TTS with emotion-adaptive synthesis
Barge-in support: interrupt naturally mid-response
Self-healing voice pipeline with automatic recovery

Proactive Intelligence

Answers before you ask.

Memory graph analysis for contextually relevant surfacing
Meeting reminders, follow-up suggestions, contextual insights
Budgeted background processing during idle time only
Based on local data — no surveillance or behavioral tracking

23 Languages

Speak any language. Ghost adapts.

English, Spanish, French, German, Arabic, Chinese, Japanese, Korean, Farsi
Twi, Ewe, Ga, Dagbani, Hausa, and 9 more
Automatic detection via Unicode analysis and NLLanguageRecognizer
Voice input/output in detected language, fully offline

Adaptive Performance

Smart resource management.

5-state degradation: Full Power → Balanced → Conservative → Minimal → Emergency
Thermal, battery, RAM awareness with graceful degradation
Speculative decoding: 3B quality at 0.6B speed (1.7–3x boost)

Verified Privacy

Privacy through proof, not policy.

AES-256 encryption at rest with SQLCipher option
Keys in Secure Enclave / Android Keystore — never leave hardware
Ed25519 verification on every model load, automatic PII redaction
Proof of locality, encryption, deletion, and policy compliance

Cryptographic Trust Root

Hardware-backed identity.

Ed25519 keypair generated in Secure Enclave at first boot
Public key exportable to auditors, courts, compliance systems
Proof bundles verifiable without Ghost infrastructure

Policy-as-Code Engine

Declarative rules. Cryptographic enforcement.

Enterprise: organizational AI rules as structured definitions
Controls: cloud escalation, language, model, token budget, content domain, memory access
Every enforcement event logged with attempt, block, and alternative offered

Memory Value Index

Knowledge as a managed asset.

Tracks referenced, stale, redundant, and high-impact memories
Teams: bottleneck detection, silo detection, cross-referencing patterns
Knowledge density scoring for pruning candidates

Engineering Innovations

Neural Cache

Compressed state (~50KB) survives backgrounding. Resume with full context.

Speculative Decoding

Draft at 80-100 tok/s, verify in one pass. 3B quality at 0.6B speed.

On-Device Distillation

LoRA adapter training during idle. Implicit feedback. Measurable improvement.

Crash-Safe Recovery

Atomic activation with VERIFIED sentinel. Per-tier quarantine. DB rollback.

Context Budgeting

Priority prompt composition within KV budget: system, tools, memory, input.

8 Agent Protocols

MCP, A2A, ANP, AG-UI, AGORA, LMOS, AP2, OASF — multi-agent ready.

Fleet Attestation

Device heartbeats verify model hashes, policies, chain integrity. Drift quarantine.

Context Fingerprinting

SHA-256 of every context window — proves what the model saw.
