| *By Andrew White ([@andrewwhite01](https://twitter.com/andrewwhite01))* | |
| This tool will enable asking questions of your uploaded text, PDF documents, | |
| or scrape github repos. | |
| It uses OpenAI's GPT models and thus you must enter your API key below. This | |
| tool is under active development and currently uses many tokens - up to 10,000 | |
| for a single query. That is $0.10-0.20 per query, so please be careful! | |
| * [PaperQA](https://github.com/whitead/paper-qa) is the code used to build this tool. | |
| * [langchain](https://github.com/hwchase17/langchain) is the main library this tool utilizes. | |
| 1. Enter API Key ([What is that?](https://platform.openai.com/account/api-keys)) | |
| 2. Upload your documents and modify citation strings if you want (to look prettier in answer) | |
