Great questions.

> 1. Does chat-with-pdfs function work with scanned PDFs?

Not yet. We don't do OCR or anything to extract text from images yet. But that would be an awesome feature, so we would love to add it in the future.

> 2. In the video example for chat-with-pdfs you show uploading a document interactively. The part of processing is quite slow. Can the tool be fed these documents offline as well?

Not as of right now. But we do have plans to make that an offline/background job so that we can feed a larger corpus of documents into it and query against it later.
