| Which plan to pick | 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. | If you're choosing Neon, it's for the agents, so Standard at $19.90 a month is the plan that matters. Month to month, so try it for one month on a real job. The free plan's chat is more basic than the free AI in Opera One, so only stay on Free if you want to plug in your own Claude or ChatGPT. | 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. |
