Daily conversations have boosted my productivity and turned rough ideas into clear responses
Grok could be improved by making its answers more consistent and easier to trust across different topics. I would also like to see better source transparency so I can understand where a response is coming from when accuracy really matters. Another area would be deeper follow-through on complex prompts. Sometimes I want it to keep the structure tighter, explain trade-offs more clearly, or give me a cleaner final answer without needing as much editing on my side. I would also improve the experience around memory and context, so it stays aligned with what I'm trying to do over a longer conversation. That would make it even more useful for ongoing work instead of just one-off questions. I would add a few practical improvements. The user interface could be a little cleaner, especially when switching between tasks or refining an answer. I would also prefer smoother integrations with the other tools and platforms I use, so it fits more naturally into my workflow instead of feeling separate. Another improvement would be better handling of longer conversations so the context stays consistent without me having to restate things. That way, context rot does not happen. That would make it more reliable for ongoing work and reduce repetitive edits on my side. The improvements I would prefer to see are better consistency across answers, and especially when I ask similar questions in different ways. It would also help if Grok were more transparent about when it is confident versus when it is inferring because that makes it easier to trust the output. I would also prefer to improve context handling for longer conversations, editing and refinement tools so I can polish answers more smoothly, and integration quality with other work apps so it fits into my workflow more naturally. The stability and uptime, especially for more demanding or production-style use, would also be important. Overall, I think the biggest theme is making it feel more predictable and dependable while keeping the speed and conversational style that makes it useful.

Attempts to be versatile but falls short of specialized performance
I use Perplexity primarily as an online search engine when I need information I use Perplexity primarily as an online search engine when I need information. However, I cannot recommend it as Google is a better web search engine, and ChatGPT is a better LLM-based answer engine. I find information…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I previously tried to do the same with ChatGPT, Claude, and Perplexity, but none of them have the ability for this up-to-date, real-time, niche, pop culture knowledge that Grok possesses."
"The biggest measurable outcome for me has been the time saved, as I can usually get to a usable draft or an answer much faster, which cuts down the time I spend rewriting or searching for wording and has improved my productivity by making it easier to move from an idea to a finished answer without getting stuck."
"Perplexity has nothing that makes it unique, and it tries to do everything at once but does nothing well."
"The initial setup was straightforward."
 

Cons

"I would rate customer support around five out of ten because it is slow and difficult human support in refund handling and we have to rely on other channels, official channels, and community help."
"Grok is already pretty good, but I don't like the voice mode. It doesn't work very well, giving very long answers and explanations and repeating certain greetings."
"Perplexity has nothing that makes it unique, and it tries to do everything at once but does nothing well."

Questions from the Community

What needs improvement with Grok?
Grok is already pretty good, but I don't like the voice mode. It doesn't work very well, giving very long answers and explanations and repeating certain greetings. It is not enjoyable.
What is your primary use case for Grok?
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...
What needs improvement with Perplexity?
The core feature and the core ranking algorithm of Perplexity should be improved. Perplexity is trying to be everything at once, such as providing stock information and e-commerce, and should make ...
What is your primary use case for Perplexity?

What advice do you have for others considering Perplexity?
