For a long time, I treated AI like a one-size-fits-all solution.
Need to write? ChatGPT.
Need to think? ChatGPT.
Need to check something? Still ChatGPT.
It worked — until it didn’t.
Over time, I realized the problem wasn’t the AI.
It was how I was using it.
Different AIs are built with different goals, personalities, and strengths. Expecting one AI to do everything well is like expecting one app to replace your browser, email, notes, and calendar at the same time.
So instead of asking “Which AI is the best?”, the better question is:
Which AI is best for this specific job?
Here are 5 emerging (and increasingly popular) AIs, what they’re actually good at, and when you shouldn’t use them.
ChatGPT — The Best All-Rounder (But Not the Best at Everything)
If AI tools were Swiss Army knives, ChatGPT would be the one most people carry.
Where ChatGPT shines
- Clear explanations and reasoning
- Writing, planning, summarizing
- Analyzing documents and data
- Turning vague thoughts into structured ideas
I personally use ChatGPT when I need to think clearly, not just generate text. In fact, I’ve had moments where it caught logical gaps in my own code before I even noticed them — something I wrote about in AI Just Fixed My Code Before I Even Realized It Was Wrong — Here’s How.
Where it falls short
- Limited real-time awareness by default
- Can sound generic if you rely on it too much
- Not very opinionated
Best use cases
- Personal productivity
- Learning new topics
- Coding help
- Planning and analysis
ChatGPT is great — just don’t expect it to understand what’s happening right now on the internet.

Grok — The AI That Understands What’s Happening Right Now
Grok, built by xAI, feels very different from ChatGPT.
The first thing I noticed?
It doesn’t try to be polite.
Where Grok shines
- Real-time awareness through X (Twitter)
- Understanding trends, debates, and public sentiment
- More direct, sometimes blunt responses
If you’ve ever wondered “Why is everyone suddenly angry about this?”, Grok is surprisingly good at answering that.
Where it falls short
- Weak at structured tasks
- Not ideal for long documents
- Requires X Premium
Best use cases
- Trend analysis
- Cultural and social commentary
- Understanding public opinion
Grok isn’t trying to help you write reports.
It’s trying to help you understand the internet’s mood.

Gemini — The AI That Lives Inside Google’s World
Gemini (formerly Bard) feels less like a chatbot and more like an extension of Google Search.
Where Gemini shines
- Strong factual answers
- Integration with Google Docs, Gmail, and Sheets
- Good at summarizing web-based information
When I need something closer to “search, but smarter”, Gemini often gives cleaner answers than scrolling through search results.
Where it falls short
- Less creative
- Very “safe” responses
- Not much personality
Best use cases
- Research
- Fact-checking
- Work documents inside Google Workspace
If your work already lives in Google’s ecosystem, Gemini fits naturally. You can explore it at https://gemini.google.com.
Claude — The AI That Feels the Most Thoughtful
Claude surprised me.
It’s not flashy.
It doesn’t try to impress.
But when you give it long documents or complex questions, its responses often feel calmer and more nuanced.
Where Claude shines
- Long-context understanding
- Thoughtful explanations
- Clear and structured writing
Where it falls short
- Fewer advanced tools
- Less ecosystem integration
- More conservative answers
Best use cases
- Reading and summarizing long texts
- Writing reflective or strategic content
- Ethical or complex reasoning
Claude feels less like a tool and more like a thinking partner.

Perplexity — The AI That Replaced My “Quick Google Searches”
Perplexity doesn’t feel like a chatbot at all.
It feels like a smarter search engine.
Where Perplexity shines
- Direct answers with sources
- Real-time web grounding
- Very fast research
I often use it when I want to confirm facts or compare things quickly — without opening ten tabs.
Where it falls short
- Not conversational
- Weak for creative work
- Limited personalization
Best use cases
- Research
- Fact verification
- Learning unfamiliar topics quickly
Perplexity is available at https://www.perplexity.ai.
Why Using Multiple AIs Actually Makes You Smarter
One thing I noticed after using different AIs for different purposes:
my thinking improved.
Not because AI is magically increasing intelligence, but because switching tools forces you to see problems from multiple angles — something I explored more deeply in Do AIs Increase Human IQ?.
Different AIs:
- Emphasize different details
- Have different blind spots
- Push you to question answers instead of accepting them
This is also why features like voice interaction matter. Talking to an AI vs typing to it can change how you process ideas — something I noticed when comparing ChatGPT Advanced Voice Mode vs Free AI Voice Tools.
Final Thoughts: AI Is a Toolkit, Not a Loyalty Test
You don’t need to “pick a side”.
The real advantage comes from knowing:
- When to use ChatGPT
- When to switch to Grok
- When Gemini or Perplexity is the better fit
The future isn’t about one AI replacing everything.
It’s about using the right AI at the right moment.
If you’ve only been using one AI so far, try this experiment:
Use a different AI for just one task this week.
You might be surprised how much clearer things become.
