Build with AI that sees your whole project.

A desktop IDE built on Code-OSS with native Ask, Agent, and Plan modes — familiar workbench, project-wide context, and edits you approve.

AI lives in ghost text, inline diffs, and the shortcuts you already use. Typing never waits on a chat panel.

Workspace folders, terminals, attachments, and open files — not just the active buffer.

Multi-file changes are proposed for review. No silent filesystem writes by default.

From install to your first guarded agent turn.

Install Altus IDE for Windows.

Use Agent mode; accept or undo file changes when you are ready.
