GPT-3 is also a classifier and data-extractor.

You could give it a couple dozen bookmarks with example classifications and then feed it a new bookmark and ask GPT-3 what category the page belongs in. Repeat for the entire data set.

For data extraction you could ask questions about the titles. Maybe have it list all machine-learning model names that appear in the set of bookmark titles.

It's pretty good at extending lists. That might require some sorting first.

Gosh, anyone else remember Google Sets? You typed in a few things, eg colors, and Google would add some more things of the same type.
