How far do we think this product is from something that use uses langchain to parse pdfs, create & store chunks / embeddings, and feed them to ChatGPT (or a local model)? Do we think there's any secret sauce?
I can say as someone who made something similar (Docalysis.com) that there's a lot of "secret sauce" in actually getting the outputs to be higher quality, especially with processing larger files. Just today I got another email from a user saying the quality was better than other AI products they tried.
I also don't use Langchain.
