What it is

Perplexity works like Google, but instead of ten blue links it writes a short answer and shows numbered sources so you can check where each fact came from.

How to start in 5 minutes

  1. Open perplexity.ai (no account needed to try).
  2. Ask a real question, e.g. "Is it safe to charge my phone overnight?".
  3. Click the numbered sources to verify the answer.
  4. Ask a follow-up in the same thread.

Is the free plan enough?

Free is enough for everyday research.

Perplexity's help centre says the Free plan includes its Best search mode and a limited number of Pro Searches; paid plans let you pick advanced models.
