What it is

Perplexity is a research-focused assistant: instead of answering from memory, it queries the live web, synthesizes an answer, and shows the sources behind every claim. A solid tool for quickly researching a topic, with the ability to check where the information comes from.

Where Perplexity stands out

  • Sourced answers: every sentence links back to web pages, easy to verify.
  • Up-to-date information, since the search happens at the moment you ask.
  • A "deep research" mode for more thorough reports.
  • A clean interface focused on question-and-answer.

Limits and precautions

  • Quality depends on the sources found: thin web coverage on a topic means a thin answer.
  • It can misinterpret or over-summarize a source — always open the links on important points.
  • Less suited to creative writing or long-form production than general-purpose assistants.
  • The free tier limits advanced/deep searches.

Access and pricing

Free access on the web and via app, with a limited number of advanced searches per day. A paid tier unlocks heavier use and more powerful models. Plans and capabilities change quickly — check current pricing on the official site.

Professional use cases

  • Fast research and monitoring on a market, regulation, or technology.
  • Preparing for meetings or tender proposals.
  • Cross-checking information found elsewhere.
  • A first bibliography on a topic, to dig into further later.

Frequently Asked Questions

Does Perplexity replace Google?

For a specific question where you want a synthesized, sourced answer — often, yes. For exploring or reaching a specific site, classic search is still useful.

Are the sources reliable?

Perplexity cites what it finds; reliability still depends on the cited sites. Open the links on sensitive points.

Can I use it for free?

Yes, with a daily limit on deep/advanced searches. The paid tier removes those limits.
