AI Code Generation

Useful when writing new code from scratch.

  1. Click the AI button in the code editor toolbar or press the shortcut Cmd+I (Mac) / Ctrl+I (Windows).
  2. Describe the desired logic in natural language in the prompt window.
    • Example: "Filter only rows where 'status' is 'active' from the input data, and count by date."
  3. Click the Generate button and AI will write the code and show a preview.
  4. If you're satisfied with the code, click Accept to apply it to the editor.

Supported Languages and Guidelines​

  • Python: Optimized for data frame processing using the polars library. Automatically follows the input (inputs) and output (output) dictionary structure.
  • SQL: Supports standard SQL syntax and appropriately maps input table names.
