Exaro for Unreal turns an instruction into playable results inside the Unreal Editor. Chat with Claude, Gemini or OpenAI using your own API keys, or your own Claude Code / Codex / Gemini CLI subscription (CLI subscriptions run read-only in this edition), and let the AI inspect your whole project with the read-only tools.

This free edition reads and explains your project. Building and changing it — gameplay systems, levels, Blueprints, materials, animation, audio, UI — needs Exaro for Unreal Pro (one-time) or Exaro Studio from exarostudio.com (one purchase: Exaro for Unreal and Exaro for Blender, the game systems library and live AI workflows, with a year of updates included). With either, changes apply immediately as one undoable step (Ctrl+Z); review before applying is optional. Licences are activated inside the editor.

Once per session it connects to the Exaro content service for signed skills, recipes and layouts (data, not code; can be turned off in Editor Preferences).
