| Which plan to pick | Start free. If you hit the daily limits or the answers feel thin, Premium at $14.99 a month gets you Claude-level quality inside a private browser. If you already pay for ChatGPT or Claude, you may not need Premium at all, since those work in any browser. | Start with the $1 free cloud credit to see if it handles your sites, then top up as you go. There's no subscription, and credits don't expire. Run the free open-source version only if you're comfortable in a terminal and want to pay your AI provider directly. | 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. |
