Building a custom chatbot for a website

Hi!

I am a data scientist and I am looking to build a small AI project. This is the project that I am thinking to build (also feel free to give me some suggestions to make it better)

It should be a chatbot that leverages both open ai api and my own custom data about the fun local activities. In the backend, it reads from my data (pdf, csv, etc format) and gives suggestions based on the user question. The data would not have any ranking, just plain text with the activitiy name, description and whether it is weekly or daily activity. The GPT then should analyze the data based on the user question and then give recommendations.

For example, if a prompt is "what are some activities I can do with my friends on saturday night", it then analyzes the text data and gives recommendations and also ranks them from the most to least fun.

Is this doable? I have been reading blogs about building custom chatbots, but they are mostly about just reading and answering based on what is available on the website. I haven't found an example of recommendations based on the question and the available data.

Thanks!
