September 2026Velocity is a self-hosted personal AI assistant and technical thought partner engineered for deep context retention and long-term memory. It features deterministic memory tiers (active session context, cognitive focus loops, and long-term mental models), hybrid storage (PostgreSQL with pgvector for semantic retrieval, SQLite FTS5 for full-text search), and secure remote access via Cloudflare Zero Trust tunnels without exposing public inbound ports.
