            Healthcare providers often need to gather patient information before appointments. 
            This demo illustrates how MedGemma could be used in an application to streamline pre-visit information collection and utilization. 
            <br /><br/>
            First, a pre-visit AI agent built with MedGemma asks questions to gather information.
            After it has identified and collected relevant information, the demo application generates a pre-visit report. 
            <br /><br/>
            This type of intelligent pre-visit report can help providers be more efficient and effective while also providing an improved experience 
            for patients relative to traditional intake forms.
            <br /><br/>
            Lastly, you can view an evaluation of the pre-visit report which provides insights into the quality of the output. 
            For this evaluation, MedGemma is provided the reference diagnosis, allowing "self-evaluation" that highlights both strengths and what it could have done better.

            capability for the displayed task and is intended to help developers and users explore possible
            applications and inspire further development.
