Arca

Your data. Your vault.
Your AI's foundation.

Arca gives every user a private, isolated vault for storing personal data - from AI memories to daily logs, lists, and preferences - securely and privately.

What Is Arca

Arca is a private data vault for your AI life.
It creates a personal data vault in your own dedicated AWS S3 bucket - where your AI assistants can store, organize, and recall data of all kinds:

Vector memories
Structured logs like meals, workouts, and habits
Notes, wishlists, favorites and preferences

Your vault is private and persistent - designed for personal AI agents to learn from your life, without ever handing that data to anyone else.
