| Which plan to pick | Try 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. | Try 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. |
