A related thing I’ve been wondering about — I have thousands of bookmarks and saved PDFs etc and I would love to have a way to scrape all the content from the URLs and PDFs and then ask questions and get answers along with links to relevant docs. Now that would be a killer app.

EDIT — answered my own question: there is indeed an OpenAI Embeddings API :

https://beta.openai.com/docs/guides/embeddings

That plus a vector similarity engine (FAISS for example) is the key to these types of apps (Thanks to Simon Willison’s blog, which he pointed to elsewhere in this thread)
