Converting text-based requirements to a live prototype includes receiving text with a natural language string. The text includes a term for a component from a design language system and the natural language string describes at least a part of an interface. The method further includes generating, by a converter module, an output string from the text by: tokenizing the text to form a plurality of tokens that include a token for the term, tagging the token with a tag for the term, and applying a rule that uses the token and the tag. Applying the rule maps the token to the component of the design language system and writes the component into the output string. The method further includes generating the interface from the output string. The interface is made with the design language system and includes the component from the output string. The interface is presented with the component to a device.
