# Test multiple prompts at once
> Compare different prompts side-by-side in the prompt playground
export const AskAlyx = ({children}) => {
const gradientId = `askAlyxGradient-${Math.random().toString(36).slice(2)}`;
return ;
};
A common development workflow is comparing multiple prompts side-by-side.
The prompt playground lets you directly compare up to three prompts at once, making it easy to evaluate performance differences, spot improvements, and identify the most effective prompt. By providing a clear, side-by-side view, it accelerates iteration, reduces guesswork, and helps you confidently choose prompts that deliver better results.
To test prompts side-by-side, use the **+ button** on the right to add new prompt objects. You can have **up to 3 prompt objects** at a time.
Then, either fill in data manually, or load a dataset and run an experiment per prompt. For more information, see [Test prompts on datasets](/docs/ax/prompts/prompt-playground/save-playground-outputs-as-an-experiment).
**Ask Alyx** to load a prompt from Prompt Hub or create a new one side by side.
