Provide URL or PDF to plugin to generate summary

I love the plugin and have been using it since last year. I have a general questions on how to use it for my needs. 1) On my iPhone Chat GPT app using version 4 Turbo, I can provide a URL and it will summarize the article for me. When I try in your plugin it says it can not access external websites? Have you not added this functionality yet? 2) What if I wanted to upload a PDF and have the plugin summarize the document for me? Is there a way to do that?
