Which plan to pickTry it on Plus with a couple of real jobs. If you hand it work most days you'll run out of credits, and that's when Pro or extra credits make sense.Start on Pro to see which jobs it handles well for you. If you hand it real work most days you will hit the limits, and Max is the plan that makes it a daily tool.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.
