GPT tool query: seeking desktop application with document support - eviltoast

What I’m looking for is some kind of desktop tool that uses the OpenAI GPT web endpoint. I’d like something where I’m able to upload one or more documents (text files) and then include them as part of the conversation/query.

I have access to the GPT-4 API and I’ve been writing Python3 code against it for some various applications. I can see how I’d write a tool that takes in one or more documents to include in the total prompt history, but I’m hoping to not have to write it myself, mostly due to time constraints.

Is there some kind of application that has a similar feature set to this that I should look at? Or, is there a wiki/site that lists off the current tools available that I could look over?
