Unity AI Assistant is Unity's official AI chat inside the editor. Unity CLI is Unity's official command line, with its own MCP server and agent plugins.
Unity AI Assistant chats inside the editor and its CLI drives the editor from a terminal. Satura Space shows you the running game and adds a Tuner, Drift, scratchpads and multiplayer testing that neither has.
The agent sets up the moment and opens Unity's real Inspector on just the fields that matter. You tune it by feel.
Run agents in parallel, each in its own side Unity project, streamed beside the game. Open a Tuner on any of them.
Up to four synced editors, each streamed with its own input. One handle call starts every player on the same frame.
Ask about anything you don't know. Drift walks you through the UI, points at the field and explains what to tweak in the Inspector.

Yes. Unity's CLI offers unity mcp and unity eval, and Unity ships plugins with skills for Claude Code and Codex. Satura Space runs those same agents in terminals beside a live stream of the game.
Unity's AI tools and the CLI's editor connection need Unity 6.0 or later. Satura Space runs Unity 6 with the Mono scripting backend.
