Assistant AI

An AI assistant for VCSSL is now available! (Launched August 2025.)

Specifically, it can:

  • Answer questions about VCSSL syntax and features
  • Answer questions about standard-library functions
  • Help draft small pieces of code / lightweight scripts

You can use this AI while logged in to ChatGPT, from the page below:

» Detailed overview, usage guide, and examples

Important note:
For practical accuracy it's effectively required to sign in with a paid ChatGPT Plus account and use the GPT-5 Thinking model. On the free ChatGPT plan, incorrect answers are frequent, so we don't currently recommend it.
