Personal opinion, based on daily use.

In short

How did I test them?

This is not a laboratory comparison, but what I experience in everyday work. I use them for brainstorming, planning outlines, gathering information, building software and websites, and creating online assistants. What follows is my own opinion, not measurement results.

ChatGPT

Brainstorming, outlines, information gathering

So far I have used ChatGPT for brainstorming, drafting plans and gathering information. I often notice that it wanders off and gets lost in the details, or worse, drifts away from the subject and sails off into other waters. In other words, it doesn’t necessarily focus on the problem to be solved.

Its strength, in my view, is the Hungarian language: it is the strongest of the three in that. Since GrokBot has existed, it has been pushed completely into the background for me.

Claude

Building software and websites

I use Claude to build software and websites, in various programming languages, mainly Java and Python. In software development, I think it is unbeatable.

In Hungarian it sometimes makes mistakes, so it is worth checking what it writes.

Grok

Online assistants with GrokBot

With the help of GrokBot I create online assistants. The assistant collects data, handles my correspondence after my approval, prepares offers, analyses and makes suggestions.

In assistance, I think it is miles ahead of its competitors. One thing is worth mentioning: my Grok Premium quota runs out faster than with the other two, so there is less room to save.

Tips

What to watch out for with all three

  • Checking: Claude and Grok sometimes make mistakes in Hungarian. It is worth checking what they write and treating it with reservations.
  • Focus: ChatGPT tends to wander off or get lost in details. Keep the question narrow, and bring it back if it drifts from the subject.
  • Price: my three subscriptions cost roughly the same. The Grok Premium quota runs out faster; with the others there is more room.
