| 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. | Run 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. |
