Which plan to pickRun a couple of real jobs on the free plan to see what they cost in credits, then take Plus on monthly billing until you're sure. Turn on 'Ask First' so it checks before spending credits. Refunds are only available within 72 hours outside the EU and UK, and only if you've used less than half your allowance.Use it free: the sidebar assistant alone is worth having, and most people never need more. Pro makes sense if you want Perplexity's research tools anyway, but don't buy it just for the browser agent, since Pro's credits are a one-off bundle. Nobody needs Max just for the browser.

  • Plans change without much notice: 'unlimited' chat and some top models were pulled in late 2026
  • Constant upgrade and credit-offer pop-ups, and mixed support and refund stories
  • Big tasks are slow, and there were outages in October 2026
  • Repeated prompt-injection attacks found by researchers in 2025 and 2026; risky with logged-in accounts
