Works where you work
Stunt Double plugs into the tools you already use. Connect Claude to run your workspace from a conversation, and wire findings into the rest of your stack.
Guides by workflow
How Stunt Double slots into the place your work already happens, from designing in Claude or Figma to shipping from a codebase and enforcing standards continuously.
Claude design
Design an artifact in Claude, publish it, and test it with AI personas without leaving the conversation.
Figma
Walk prototypes with personas and re-check the built flows automatically when a file changes.
Figma Make
Publish a Make site and have AI personas try to use it before an engineer touches it.
Codebases
Wire Stunt Double into your coding agent so every preview deployment is walked by a persona before merge.
Validation
Turn brand, tone, legal, continuity, and design-system standards into checks that run on every deploy.
