The quick answer
- ChatGPT - writing, ideas, explaining a topic step by step, planning.
- Gemini - when you live in Google: Gmail, Docs, YouTube, Android and photo edits.
- Perplexity - search-style answers with sources you can click and check.
Try the same question in all three
The best way to choose is to test. Ask all three: "Explain UPI to my parents in 5 simple sentences." Then ask: "What changed in UPI rules this month? Give sources." You will quickly see which one fits each kind of question.
The pro move: use them together
- Research the facts with Perplexity and open its sources.
- Write the draft with ChatGPT: "Using these facts, write a short email to my team."
- Send it from Gmail with Gemini's help to polish the tone.
Free or paid?
All three have free plans that are enough to learn. Paid plans add stronger models, longer chats and more uploads. Start free, and pay only when you hit a limit you actually feel.
Lesson learned
There is no single best AI. Pick the right tool for the job, and check important facts yourself.
