Switch AI engines

Claude Code is the default and our recommendation. Codex, Kimi and OpenCode are in the engine picker if you prefer another.

Your workspace belongs to you, not to the engine. Switching never moves, converts or touches your projects: same folders, same previews, same everything, different brain.

Each engine uses its own official sign-in with your own account, so the first time you switch to one it will ask you to sign in once.
