My main use cases are twofold. One is when I read something on Twitter, Grok can explain it to me, even if it's just an image or if it requires a lot of background information. Grok can always give me the context to understand something. The second use is when I have pop cultural questions about memes, Internet phenomena, or very recent trends; Grok provides the most up-to-date information and the best insights into niche topics.
