The cold start
Every time you switch between ChatGPT, Claude, Gemini, or any other AI tool, you start from zero. No memory of what you’re working on. No context about how you think. No continuity. 4StaX fixes that. It’s a personal data OS built for the AI era — starting with a cross-provider memory layer and expanding into a full data vault, marketplace, and intelligence platform where you own, control, and optionally monetize your data.Memory
Persistent context across every AI provider you use
Vault
Encrypted storage with granular permissions and full audit trail

The stack
The name 4StaX refers to the four layers that compound over time:| Layer | What it does |
|---|---|
| Memory | Persists context across every AI session |
| Vault | Encrypted, permissioned storage you control |
| Marketplace | Opt-in data sharing with transparent earnings |
| Intelligence | Compounds into a cognitive profile over time |
How people use it
- Developers who switch between Cursor, Claude Desktop, and ChatGPT and are tired of re-explaining their stack every session
- Power users who want their AI interactions to actually build on each other over time
- Teams who need shared memory with proper access controls and audit trails
