To auto-generate a list of theme words using AI (LLM), select Generate List in the Create Vocabulary Puzzle window, or click the New button on the Theme List tab of the Word List Manager. The Pro Grid Filler's Place Theme Words feature also has a button to generate the theme words to use.
The Generate Theme Words window has an input box where you describe the theme that you want to use. This will be used by the language model to generate the theme words. For example "Alpine plants" would generate a list of names of Alpine plants. In the boxes below you can specify the maximum word length and the number of words that you want to generate.
When you click Generate, the language model will generate the list of words for you (internet connection and remaining AI token credit required).
In the Word List Manager you can also add new words to an existing theme list, by selecting Generate and add theme words from the Word List menu.
