Lunvy

AI life OSin development · lunvy.app

A mobile super-app where you talk to an AI that manages your life modules (finance, journal, tasks) by executing real actions, not just answering.

How it's built

  1. Orchestration

    An orchestrator decomposes requests into sub-agent runs that call domain tools through an invisible MCP layer.

  2. Action safety

    The AI can't move money on its own. Financial actions pass a two-step confirmation with atomic budget guards, and every action is undoable.

  3. Security

    Per-user envelope encryption (AES-256-GCM), GDPR erasure via crypto-shred, blind-index lookups over encrypted data, prompt-injection wrapping before any LLM call.

  4. Cost engine

    Split user/model history with token-triggered compaction and a byte-stable prompt prefix for an 88% KV-cache hit rate.

  5. Stack

    Expo React Native, NestJS, PostgreSQL, Redis, Prisma. One monorepo.
