Limitations of AI-generated stores
AI-generated stores serve as a foundation but have several limitations:

- Generic design: Default themes lack unique branding without further customization.
- Limited integrations: Complex ERP, CRM, and marketing system integrations need additional development.
- Content gaps: Rich product descriptions and marketing content often require human input.
