Everything a click away
Packs, not clutter.
Seven presets and ten feature packs tune the surface without installing or removing code. Every tool remains a click away when its pack is enabled.
Inside Nexis
A workspace
worth opening.
Real screens from the editor, agent, terminal, and the tools around them.
Welcome screen
A particle-built wordmark and the shortcuts you need first. It is what you see when no tabs are open.
In motion
One window,
every job.
A 26-second loop recorded live from the app: the welcome screen, Spotlight, the terminal, the AI agent, Documents and theme switching. Source on GitHub
