ChatGPT, Claude, or Gemini: which is better?

Do free AI tools have usage limits?
Yes, all have limits in the free plan (messages per day, image generations, characters processed). For intensive use you need a paid plan, which is typically €15-25/month.
Is it safe to use AI with confidential data?
With caution. Don’t enter personal data, passwords, medical information, or business secrets into public AI. For enterprise use with sensitive data, look for enterprise versions with privacy guarantees.
Conclusion
For 90% of daily tasks, ChatGPT and Perplexity cover practically everything for free. Add Bing Image Creator for images and Gamma for presentations. With these four tools you have a complete productivity assistant without spending a euro.
