Stop Downloading Everything. Pick the Right Tool. (Your Computer Thanks You.)
There are thousands of AI tools. You need exactly five. Maybe six if you count the one that turns your selfies into renaissance paintings. (You don't need that one either.)
Each of these tools is free to start, runs in your browser, and solves a different problem. Learn these five and you cover 95% of what AI can do for you today. The other 5% is generating pictures of cats in space.

🔬 Demo: Same Question, Four Answers
To see how they differ, ask all four the same question:
"What are 3 emerging trends in [your industry] for 2026? Cite your sources."
| Tool | What You'll Notice |
|------|-------------------|
| ChatGPT | Long, detailed answer. Good structure. May guess sources. |
| Claude | More cautious. Will say "I don't have real-time data" if it can't browse. Safer. |
| Gemini | Pulls from Google Search. More current. Links to actual articles. |
| Perplexity | Every claim has a citation. Best for research you need to verify. |
The pro move: Use Perplexity for research, then ChatGPT or Claude to turn that research into output.
