Feature Request: PDF attachments

[zhiyuanzhai]

In my daily work, I often use LLMs to summarize PDF articles, so that LLMs could help me read them more efficiently. It could be great to support PDF attachments while chatting with my LLMs. This feature has been realized in multiple online LLM applications, and here I would like to suggest such a feature in this app for local LLMs.

I would also like to know whether PDF attachments are feasible or necessary in local LLM applications. Thanks!
