# Keep product changes aligned with your design system

Generate updates that use your existing components and patterns, so new changes stay consistent with the rest of your product.

### Build with the components your product already uses

Fei Studio generates changes using your existing UI components and structure, so nothing is recreated or approximated.

### Maintain consistency as the product evolves

New changes follow the same patterns and conventions as the rest of the system, reducing drift and keeping the product coherent.

# Fei Studio empowers the whole team

Including Product Managers, Designers & Engineers

### Use cases

[Validate Product Ideas](/content/use-cases/validate-product-ideas/index.html)
Turn early ideas into production-ready changes, release them behind feature flags, and learn from real user behavior before committing fully.

[Prototype With Real Code](/content/use-cases/prototype-with-real-code/index.html)
Designers prototype new experiences directly in the product environment instead of relying only on static mockups.

[Accelerate Feature Delivery](/content/use-cases/accelerate-feature-delivery/index.html)
Move from product requests, screenshots, or tickets to production-aligned pull requests faster by reducing handoffs.

[Improve Existing Features](/content/use-cases/improve-existing-features/index.html)
Refine existing product experiences and workflows without rebuilding them from scratch.

[Refactor Legacy Interfaces](/content/use-cases/refactor-legacy-interfaces/index.html)
Modernize legacy UI surfaces and migrate them toward current component standards while preserving the structure of the real codebase.

[Rapid Product Iteration](/content/use-cases/rapid-product-iteration/index.html)
Explore multiple variations of product flows quickly inside the real product environment to accelerate discovery and refinement.

[Stakeholder Demos](/content/use-cases/stakeholder-demos/index.html)
