Nexus

The interface between AI and your product.

Nexus is the interface that sits between large language models and the thing you’re building, and runs entirely on your Mac. Ask in plain words and watch your site change live. Every finished task is saved locally, and nothing goes out until you publish.

Run your own AI models locally on your Mac, right inside Nexus. Nexus adds the visual development environment without another monthly bill or credit system. Nexus is a one-time purchase. No subscription. Buy it once and it’s yours.

Why Nexus

Your Work. Your Mac. Your Rules.

Stop paying for another development environment that charges monthly fees and limits your work with credits when you already have your own AI coding agents.

Nexus is a native macOS integrated development environment that gives you a visual workspace for building with AI. Run open models like Qwen, Llama and Gemma locally on your Mac, right inside Nexus. Nexus provides the interface, not the AI agents.

Your projects stay on your Mac, you decide when to publish, and Nexus never charges subscription fees or sells credits. Pay once, use it forever.

AI models are separate from Nexus. You download and run them yourself, on your own Mac.
