ResuLLMe is an AI tool hosted on Streamlit's platform. Streamlit is an open-source Python library that allows developers to create custom web applications for machine learning and data science.

The ResuLLMe tool presumably takes advantage of these capabilities. As its function isn't explicitly stated, it could be used for a variety of tasks such as data visualization, experimentation, or deploying AI models, consistent with the possibilities offered by the Streamlit platform.

However, precise functionality, application areas, strengths and limitations, and the specific problem this tool solves are to be determined when further information is provided.

It's worth mentioning that being hosted on Streamlit offers potential benefits including quick prototyping, ease of use, and interactivity features, though these could vary for 'ResuLLMe' depending on how it's developed.
