Our verdict: The Perplexity app answers questions with cited web sources and, unlike the website, can read and create files in folders you allow. The free plan covers simple everyday questions with limited weekly use of the best models; research, file creation and higher limits need Pro. Installation goes through the Microsoft Store and a Perplexity account is required.

About Perplexity

Perplexity is an AI answer engine made by Perplexity AI, Inc. You ask in text or by voice and get an answer with citations to the sources it used, and you can keep asking follow-up questions in the same thread. The desktop app adds what the website cannot do: it works with files and folders on your computer that you choose, opens from a floating task bar over other apps, and supports Remote Access to start and monitor desktop tasks from your phone or the web.

The free plan includes cited answers and basic AI models with limited weekly use. Pro, listed at $17 per month billed annually, raises the limits and adds deep research, a choice of top models, Perplexity Computer and document and app creation; Max is aimed at heavy use. On Windows the app installs and updates through the Microsoft Store, including when you start from the website installer.

What it does well

  • Cited answers. Every answer links to the web sources it was built from.
  • Local files and folders. Reads and creates files only in folders you give it access to.
  • Floating task bar. Opens Perplexity on top of the app you are working in.
  • Remote Access. Start and follow desktop tasks from another device or the web.
  • Threads and library. Follow-up questions and a searchable history of past sessions.

Who it is for

Good fit
