Zero-knowledge encrypted memory library for personal AI agents

VaultMem

A zero-knowledge encrypted memory library for personal AI agents.

What This Is

VaultMem is an embeddable open-source library that any platform developer can integrate to give their users persistent, encrypted, portable AI memory — where the platform operator cryptographically cannot read user data.

This is the concrete implementation of Layer 1 (Personal Storage Layer) of the Memory-as-Asset framework proposed by Pan, Huang & Yang (arXiv:2603.14212, March 2026).

The Problem

Every existing AI memory library (mem0, Zep, LangMem, Letta) stores user memories in plaintext on the platform's servers. The platform owns your memory. Switch platforms and you start from zero.

VaultMem flips this:

• User controls the encryption key (passphrase → Argon2id → session key)
• Key lives only in RAM during active sessions — never written to disk
• Platform developer embeds the library but cryptographically cannot read memories
• Users export their encrypted vault and take it anywhere
