Arca gives every user a private, isolated vault for storing personal data - from AI memories to daily logs, lists, and preferences - securely and privately.
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:
Your vault is private and persistent - designed for personal AI agents to learn from your life, without ever handing that data to anyone else.
Use passkey or magic link - no passwords needed.
Arca provisions a private S3 bucket dedicated to you.
AI assistants like Cloe and portable memory like Memkit use temporary credentials to store and retrieve your data securely.
All your personal data - vector and structured - lives in one place.
Your vault is isolated and only accessible through short-lived keys.
All data secured within Arca's AWS environment.
Works with any AI app through an open SDK.
Export or move your vault anytime in your preferred data format.
