Core Capabilities

Everything you need to go from raw idea to validated design, without strictly defined wireframes.

Backlog to Prototype

Paste a user story or feature brief. Get a fully interactive prototype with real components in minutes.

Figma-Native Output

Generate high-fidelity designs—not wireframes. Ready for handoff to your engineering team.

Design System Aware

Import your tokens, typography, and components. Every generated screen matches your brand.

Auto User Flows

Describe a feature and we map the complete user flow, decision points, and screen transitions.

Bring Your Own LLM

Use OpenAI, Gemini, or Claude. Choose the model that fits your team's needs and budget.

Human in the Loop

AI proposes, you decide. Review and refine every screen before finalizing the prototype.

Three simple steps to accelerate your workflow.

Paste your user story or feature brief. Spacecraft understands product context.

AI builds interactive prototypes and high-fidelity Figma screens using your system.

Hand off polished Figma files to designers and testable prototypes to stakeholders.

Stop waiting weeks for prototypes. Give your product and design teams the toolkit that ships validated ideas faster.
