Nextain

The AI you build and truly own

Nextain is an AI infrastructure company built to close the gap between the AI we dream of and reality. Instead of leaving everything to the cloud, we build an AI that lives on your own device and shares your memory — truly yours. For individuals, a Visual Agent you own; for enterprises, AI transformation built on top of it.

Phase 0-7 Complete

One philosophy, three products

A personal Visual Agent that lives on your device, enterprise AI transformation built on top of it, and education to understand AI — all from one belief: an AI that's truly yours.

Personal Visual Agent

Naia OS

Your own AI friend on your PC that remembers you — a Visual Agent

→Runs on your own device — conversations, memory, and data stay with you
→It remembers — still there next time you open it
→Tell it to do things — files, search, coding
→Stays on after you close it — replies on Discord
→Stored on your computer only — nothing goes to the cloud
→Apache 2.0 open source — nothing hidden
→Free to start — no API key needed
→5,700+ skills — keeps getting more capable
→Just talk to it
→Windows desktop app

Enterprise AX

Naia AX

Enterprise AI transformation — from infrastructure to AI services

→ Transform enterprises to run on AI through infrastructure transformation, AI service development, and revenue share
→ Built fast with Naia Business ADK, deployable in air-gapped and on-premise environments
→ Starnion builds and operates AI web services — first proven on onmam.com

AI Education

AieDu

Education to understand and navigate the AI era

→AI teaches with 23 research-based pedagogies
→AI coding curriculum with Monaco editor + in-browser Python execution (Pyodide)

→14 languages supported, per-organization custom curriculum
→Enrollment to certificates — live now
→Air-gapped and military deployments supported

What's underneath

What makes a usable app keep getting better

Built with itself

Naia is developed using Naia. AI writes the code, humans set the direction. This is how Phase 0-7 got done in 30 days.

How we build

AI Native Open Source

AI Slop isn't just bad code — it's contributing without understanding the project or its community. Nextain builds a structure where AI understands project context and passes adversarial review from an upstream maintainer's perspective — creating an open source ecosystem grown together with AI.

Local-First, Private by Design

Memory, personality, and conversations stay on your device. No data leaves unless you choose otherwise. Your data, your decision.

Solid AI Infrastructure

In the enterprise, AI running without understanding the business context is the same AI Slop problem. Nextain builds infrastructure for AI agents that understand your systems and operate safely within them.

Vision

With your own AI

"In an era where we must live alongside AI, we inevitably share more and more with it. Yet the reality of entrusting a cloud AI — opaque and subject to change at any moment — as our partner leaves an unavoidable sense of unease. Nextain builds on transparent open source to create a trustworthy AI that exists only on your computer, shares memories with you, and grows alongside you — the one and only AI that is truly yours."

- Luke, Founder of Nextain
