# Simulation Types & Templates

> The research questions Rehearsals answers today, the templates you can start from, and how stimuli are presented

## Starter Templates

Rehearsals simulations cluster into a handful of research jobs, and the product ships a starter
template for each. Pick one when you [start a new Rehearsal](/docs/platform/new-rehearsal), and use it
as-is or edit it.

<CardGroup cols={2}>
  <Card title="Concept Testing" icon="lightbulb">
    Put an early idea in front of your audience and hear what would actually make them try it.
  </Card>

  <Card title="Compare Ad Creatives" icon="clapperboard">
    Run a head-to-head on your ads and learn which one lands, and why it wins.
  </Card>

  <Card title="Competitive Analysis" icon="chess">
    Understand the real trade-offs people weigh when they pick someone else.
  </Card>

  <Card title="Test Pricing" icon="tag">
    Pressure-test price points and packaging before you commit to one.
  </Card>

  <Card title="Test Product or Brand Concept" icon="scale-balanced">
    Gauge first impressions of a name, positioning, or look before launch.
  </Card>

  <Card title="Discover New Audiences" icon="users-viewfinder">
    Explore segments you don't reach today and what it would take to win them.
  </Card>
</CardGroup>

<Tip>
  Templates are starting points, not straitjackets. Every question can be edited, and the built-in
  question guidance (see [Asking Good Questions](/docs/methodology/asking-good-questions)) helps you
  keep edits neutral.

## How Stimuli Are Presented

When a simulation includes creative or product artifacts (which you upload under
[Content](/docs/platform/content-and-data)), the researcher presents them during the interview as
numbered stimuli ("Artifact #1, Artifact #2…"), revealed at the right moment, and asks the replica
to react to them or choose among them. A simulation can also include no artifacts, which makes it a
purely verbal interview.
