About tplus1
From an idea to a running simulation.
tplus1 is a browser workspace for creating, inspecting, and sharing interactive simulations. Describe what you want; the agent builds the project and chooses Custom, Rapier 2D, or Rapier 3D.
01
Describe
Start with the system, interaction, or scene you want to make.

Keep prompting, edit parameters, replay, fork, export, or share the result.
The project stays yours.
Every simulation is stored as readable project files. You can inspect the configuration and source, change the runtime, and export a portable package.
