Langchan usecase? Just wanted to double check

[avikCogni]

Hey! So I am creating a webapp where users can upload documents like textbook snippets, and can obtain study materials generated by AI. I am using Google's Gemini model to parse through uploaded documents and generate text.

However, I wanted to ask online whether Langchain would be useful in my project? I aim to generate multiple materials and parse them on the website, so the output parsers and chains seem useful to split up data.

In addition, I was wondering whether a vector database would be useful with fileuploads. As in, would storing the uploaded files in a vector database, then generating responses, be faster than uploading the file to the model itself and directly asking to summarize?

Please let me know, I am very curious regarding the tool, Thanks!
