More specifically, FetchFox is targeting a specific niche of scraping. It focuses on small scale scraping, like dozens or a few hundred pages. This is partly because, as a Chrome extension, it can only scrape what the user's internet connection can support. You can't scrape thousands or millions of pages on a residential connection.
But a separate reason is, I think that LLM's open up a new market and use case for scraping. FetchFox lets anyone scrape without coding knowledge. Imagine you're doing a research project, and want data from 100 websites. FetchFox makes that easy, whereas with traditional scraping you would have needed coding knowledge to scrape those sites.
As an example, I used FetchFox to research political bias in the media. I was able to get data from hundreds of articles without writing a line of code: https://ortutay.substack.com/p/analyzing-media-bias-with-ai . I think this tool could be used by many non-technical people in the same way.
