Question: Is there a tool that can summarize content from various file types and URLs directly in Slack?

If you need a tool that can summarize content from a variety of file types and URLs right in Slack, Q is a great option. Q is an officially certified Slack app that uses OpenAI's GPT-4 to summarize text from a wide range of URLs and files. It can handle many file types, including audio, video, PDF, image, Excel and Word files, as well as Google Slides, Docs and Sheets, and Notion pages. You can install Q for your Slack workspace and use it with the @Q command, so it's easy to integrate into your team's workflow.

Another tool worth considering is TLDR This, an AI summarization service that can digest long articles, documents and research papers into a shorter form. You can upload files in PDF, doc and docx formats, paste in a URL or paste text, and the service offers features like instant summarization, article metadata extraction and a browser extension for summarizing web pages with a click. It's good for people who need to process lots of text.
