Vault
Your knowledge.
Organized by time.
Every fact is scored for importance and decays naturally over time. Recent memories stay vivid. Old ones gracefully fade. Just like real memory.
Temporal Decay
Relevance scores decrease with time
Reinforcement
Repeated topics stay stronger
Relationships
Facts connect to people, places, topics
Search
Ask anything.
Get answers instantly.
Search by meaning, not keywords. Ask questions like you would ask a friend who remembers everything.

Under the Hood
Built for power users.
Obsessed with performance.
Real-Time Transcription
WhisperKit-powered speech recognition with <3% word error rate on large-v3 model. Automatic language detection across 7 languages. Audio transcribed and immediately discarded.
Sub-Second Search
Hybrid HNSW vector similarity + FTS5 full-text search. Query 100,000+ facts in under 200ms with intelligent relevance ranking. Find anything by meaning, not just keywords.
Living Knowledge Graph
10 node types (People, Organizations, Places, Topics, Events, Documents, Facts, Sessions, Products, Actions) connected by 17 relationship types. Rebuilt from encrypted storage in <2 seconds.
Temporal Memory
Five decay types from Permanent to Ephemeral (3 days). Facts are scored, reinforced by repetition, and naturally forgotten. The system mirrors how real memory works.
Military-Grade Security
AES-256 encryption at rest via SQLCipher. E2E encrypted sync with user-held keys. PIN-derived secondary encryption for sensitive facts. Zero-knowledge architecture.
Screen Intelligence
Vision framework OCR captures screen context at 5-second intervals during active use, 30-second when idle. Privacy filters exclude sensitive windows. Smart deduplication prevents redundant captures.
Vim-Style Navigation
Full keyboard-driven interface for power users. j/k to navigate, gg/G to jump, / to search, : for command palette. Navigate your entire memory without touching the mouse.
Cross-Platform Sync
Offline-first architecture between Mac and iOS. Intelligent conflict resolution when reconnected. Only encrypted facts transfer—never raw audio or documents.
Production Architecture
Built with TCA (The Composable Architecture) for bulletproof state management. Swift 5.9+ with modern concurrency. Exhaustive async handling with proper cancellation.
The relevance formula
relevance = importance × (0.5days/half_life) × reinforcement
