# HyperSkill Studio (authoring)

Building simulations in the HyperSkill authoring tool.

HyperSkill Studio is where 3D simulations are built, in a browser or on Windows. The same app plays them.

* [Virtual entities](/hyperskill-studio-authoring/virtual-entities.md): the objects, people and spaces you build with, and how to bring your own in.
* [Authoring a simulation](/hyperskill-studio-authoring/authoring-a-simulation.md): making your first one, then the scene, inspector and settings.
* [State machine reference](/hyperskill-studio-authoring/state-machine-reference.md): making the simulation react, with triggers, transitions, conditions and actions.
* [AI features](/hyperskill-studio-authoring/ai-features.md): conversations, AI chat, agents and PDF question answering.
* [Mixed reality](/hyperskill-studio-authoring/mixed-reality.md): building for passthrough, and spatial anchors.
* [Media](/hyperskill-studio-authoring/media.md): images, audio and documents.
* [Publish](/hyperskill-studio-authoring/publish.md): getting a finished simulation to people.
* [Multiplayer](/hyperskill-studio-authoring/multiplayer.md): running a simulation with several people in it at once.
* [Your sims and assets](/hyperskill-studio-authoring/your-sims-and-assets.md): managing them afterwards in HyperSkill Platform.
