5. You Don't Have to Choose Only One
One of the biggest mistakes beginners make is thinking they need to select one AI assistant and use it for everything.
You can use several AI tools together.
For example:
Research → Perplexity
⬇️
Analyze information → ChatGPT / Claude
⬇️
Create presentation → Gamma / Canva
⬇️
Create images → ChatGPT / Midjourney
⬇️
Write code → ChatGPT / Claude / GitHub Copilot
This approach can be much more powerful than relying on a single AI application.
