Deep search/deep research in grok, chatgpt, perplexity etc works much better. It can also do things like search in different languages. Wonder about something in some foreign country? Ask it to search in the local language and find things you won't find in English.

Yeah, this is one of my favorite use cases. Living in Europe, surrounded by different languages, this makes searching stuff in other countries so much more convenient.
