Which plan to pickTry the Free plan for a week to get a feel for how many credits a real task uses, then move to the $20 Pro tier. Only go higher if you run out most months or you want it to publish websites for you.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.

Pros and cons

AttributeManusComet
Pros
  • You describe the result, not the steps
  • Strong at research, reports and first-draft decks
  • Scheduled tasks turn it into a hands-off research assistant
  • Apps for phone, desktop and browser
  • Free on Mac, Windows, Android and iPhone
  • Feels like Chrome, with your extensions and bookmarks
  • Answers about the page come with sources you can check
  • Comet Plus is included with Perplexity Pro and Max
  • Good at summaries and comparing tabs
Cons
  • Credits are hard to predict and one big task can drain the monthly allowance
  • Output needs checking, and it can waste credits on dead ends
  • Not suited to automations that must run the same way every time
  • Few direct app connections compared with the automation tools
  • Pricing page does not load without JavaScript, so plan details are hard to confirm
  • Repeated prompt-injection attacks found by researchers in 2025 and 2026; risky with logged-in accounts
  • The agent is slow and sometimes gets stuck or gives up halfway
  • Browser control moved behind Computer credits in September 2026, so Pro users lost an included feature
  • Paying users complain of quiet limits, model downgrades and features being removed
  • Amazon sued over its shopping agent, and the case is still running
