 ## Possible enhancements
 
 - **More paper sources**: Add support for more paper sources (e.g. PubMed)
 - **Chat history**: Add a chat history to the internal prompt of the Paper Buddy tool. This would allow LLM to not only take into account the current question and the paper content, but also the previous questions and answers. 
+- **Better UI**: Improve the user interface and user experience of the app.
+- **Open-source Model**: Use an open-source model for the LLM and Embedding models. Could be quantized, to save resources.
+- **Downloadable summaries**: Allow users to download the summaries.
+- **Choice of prompt**: Allow users to choose the prompt for the LLM model.
