About prmpts.AI
prmpts.AI is a prompt sandbox platform designed for prompt engineering and testing. It allows users to write, test, and refine prompts in an interactive environment before deploying them. The platform appears to support multiple AI models, with support for GPT-3 models like text-davinci-003. Users can input variables (such as 'fruit' in the example), run prompts, and preview outputs with token counting to understand API usage. The tool targets developers and AI practitioners who need to experiment with different prompt variations and optimize their prompt engineering workflow.
