# Evaluators overview
> Browse and register custom evaluators across your project.
The **Evaluators** page (sidebar → **Evaluators**) is where you see all the finetuned / registered evaluators from all projects. This serves as a single pane to view the true power of Luna Studio and how it has helped you.
## Register an evaluator
Once an evaluator reaches **Fine-tuned**, the **Register evaluator** action appears in the row's Actions cell. Clicking it opens the same modal documented in [Register an evaluator](/luna-studio/ui/runs/register-evaluator). This page does not run registration preflight before opening the modal; backend checks can still reject the submission, for example when the Splunk Agent Observability connection or evaluator contract is unsupported.
## Where to go next
Pick a template or write a custom prompt in the run creation flow.
Understand the statuses behind each evaluator's source run.
Publish an eligible Fine-tuned evaluator to the Splunk Agent Observability evaluators store.
Launch a training run that produces an evaluator.
