# How to bind an evaluator to a dataset in the UI
# Automatically run evaluators on experiments

While you can specify evaluators to grade the results of your experiments programmatically (see [this guide](./evaluate_llm_application) for more information), you can also bind evaluators to a dataset in the UI.

While you can specify evaluators to grade the results of your experiments programmatically (see [this guide](./evaluate_llm_application) for more information), you can also bind evaluators to a dataset in the UI.
You can grade your experiment results in two ways: **programmatically**, by specifying evaluators in your code (see [this guide](./evaluate_llm_application) for details) or you can **automatically run evaluators** defined in the UI. By binding evaluators to a dataset in the UI, they'll automatically run on your experiments. These UI-configured evaluators complement any you've set up via the SDK. We support both LLM-based and custom Python code evaluators.

Once you have saved your new evaluator, **subsequent** experiment run from the dataset will now be evaluated by the evaluator you configured. Note that in the below image, each run in the experiment has a "correctness" score.

Once you have created an evaluator, **subsequent** experiments on that dataset will be automatically graded by the evaluator(s) you configured.

Would be good to add a "Next Steps" section at the end of the doc. Can link out to:
-evaluation/how_to_guides/analyze_single_experiment
-evaluation/how_to_guides/compare_experiment_results
-evaluation/how_to_guides/audit_evaluator_scores
