# Experiment in Playground
> Run, compare, and share prompt experiments in the Playground with evaluators, comparison views, and saved Playground views.
export const AskAlyx = ({children}) => {
const gradientId = `askAlyxGradient-${Math.random().toString(36).slice(2)}`;
return ;
};
Use Playground when you want a fast UI loop: load a prompt, run it on data, score with evaluators, compare runs, and keep the best setup.
## Run an experiment
**Ask Alyx** to attach your dataset and run the experiment for you.
Open Playground, load your prompt, then select a dataset (or replay a production span).
Add [evaluators](/docs/ax/evaluate/evaluators) so each output is scored automatically.
Click **Run**, then open **View Experiment** to review outputs, latency, tokens, and evaluator scores.
## Compare experiments
Once you have multiple runs on the same dataset, open **Compare Experiments** to inspect:
* Output differences
* Evaluator deltas
* Summary metrics by run
* Regressions vs baseline
If you need full programmatic workflows, use [Experiment in code](/docs/ax/improve/experiment-in-code).
## Playground views
A **Playground View** is a named snapshot of your Playground session.
It stores:
* Prompt messages and tools
* Model and parameter configuration
* Dataset or span context
* Generated results and scores
Use views to save progress, share a setup, or branch experiments without rebuilding from scratch.
