What it does

The AI Toolkit allows founders to build AI-powered applications and agents using TypeScript, enabling automation and intelligent decision-making in their products.

When to use it
  • •Building a chatbot that needs to understand and respond to user queries
  • •Creating a predictive model to forecast user behavior or sales trends
  • •Developing a virtual assistant that can perform tasks autonomously
Ready-to-paste prompt
ai.predict('What is the weather like today?', { model: 'weather-forecast' })
Heads up: Ensure you have the correct TypeScript version installed, as the AI Toolkit requires TypeScript 4.8 or higher to function correctly
