Leo Premium

$14.99/mo, or $149.99/yr

Daily users who want better answers and fewer limits.

Comet Plus

$5/mo

Readers who want partner publishers' paywalled articles.

Perplexity Pro

$20/mo, or $200/yr

Anyone who wants the agent to do tasks for them.

Perplexity Max

$200/mo, or $2,000/yr

Heavy users running many tasks in the background.

Which plan to pickStart 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.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.
