Best forAnyone who wants quick, sourced answers to factual or current-events questions instead of a list of links.
Not great forLong-form writing or deep document work, and free users who hit weekly usage limits and get only basic models.
Recent change Launched Perplexity Computer (cloud agent) in Feb 2026, reaching Pro in Mar 2026; Personal Computer for Mac (Apr) and Windows (Jul 2026); dropped its ad strategy for subscription-first in Feb 2026.
Perplexity is an answer engine. Instead of a list of links, you get a written answer with numbered citations to the pages it used, so you can check where each claim came from. That makes it well suited to factual questions and anything current.
The free plan covers everyday searches with basic models and a weekly usage limit. Pro, at $20 a month, adds access to top models from OpenAI, Google and Anthropic and lets you choose between them. Perplexity has also added agent features and desktop apps in 2026, but its core job is still the same: quick, sourced answers.
It is less useful for long-form writing or deep work on your own documents; a chat assistant or a notebook tool fits those better. Privacy: Perplexity’s AI Data Retention setting is on by default, so your data can be used to improve its AI. Turn it off in Account Settings, then Preferences.
