Work with memory

Why Nexsus — The substrate

Your AI’s memory, on your terms

Powerful where it matters, private by default.

Private & isolated

Every customer gets a separate, walled-off workspace at the database level. Your data is never mixed with anyone else’s.

Works with any AI

Claude, ChatGPT, Gemini, Claude Desktop — and anything that supports the open MCP standard. One workspace, every assistant.

Persistent memory

Nexsus — The substrate remembers across sessions and structures your knowledge, so your AI keeps getting smarter about your world.

You own your data

Export it any time, delete it for good. Cancel and your workspace is removed — we’d rather promise deletion than hoard it.

Secure by design

Email-and-password sign-in, encrypted in transit, database-enforced isolation — security built in, not bolted on.

Ready in minutes

Nothing to host. Sign up, connect your assistant, and you’re working — today.
