Quickstart

This guide takes you from a new account to your first checklist run. It should take a few minutes.

1. Create a workspace

When you first sign in, Stunt Double prompts you to create a workspace. A workspace holds your projects, members, and billing. Give it a name that matches your team or company.

Sign-in is passwordless: request a magic link by email, or continue with Google.

2. Create a project

Inside the workspace, create a project for the product or surface you want to test. A project keeps related actors, checklists, and runs together, so a team working on several products can keep them cleanly separated.

3. Create an actor

An actor is the AI assistant that does the work. When you create one you give it:

  • Instructions that describe who the actor is and how it should behave.
  • Knowledge the actor can draw on (facts about your product, test accounts, conventions to follow).
  • Capabilities, such as browsing the web or reading email, that decide what the actor is allowed to do.

For a first run, a browsing-capable actor with a one-paragraph description of your product is plenty.

4. Run a checklist

A checklist is a set of steps you want verified, written in plain language, for example:

  1. Open the pricing page.
  2. Confirm the Pro plan shows a monthly and an annual price.
  3. Start the signup flow and confirm it reaches the email step.

When you run the checklist, the actor opens a hosted browser, works through each step, and reports whether it passed or failed, with a screenshot and a short explanation for each one.

5. Review the run

Every run is recorded. Open the run to:

  • Replay the session and watch what the actor did.
  • Inspect each step, its result, and the screenshot at that moment.
  • See any insights the platform surfaced from the run.

Next steps

  • Read Core concepts to understand interviews, workflows, and insights.
  • Automate runs from your own tooling with the API, or connect Claude through the MCP server.
