NexxusOS
Desktop
A local AI desktop environment built for memory, tools, files, browsing, and real agency.
NexxusOS Desktop gives you a personal AI instance that lives on your machine, remembers across sessions, works with your files, searches the web when needed, and grows into a capable local assistant.
// 01 · overview
What is NexxusOS Desktop?
NexxusOS Desktop is a local AI workspace. Instead of treating AI like a disposable chat window, NexxusOS gives each user their own persistent agent that can remember, search, read files, work with documents, and use tools.
It runs as a desktop app on your own machine. Your agent, your memory, your files, all in one place.

Switch LLMs in seconds
NexxusOS Desktop lets you swap the underlying language model without reinstalling or losing your memory, settings, or files.
Pick the model that fits your workflow, whether it is local, remote, or experimental, and keep your agent experience consistent.
