Comet vs Perplexity: pricing and free tier side by side

Comet vs Perplexity

Amo and Pimi: Which one to choose between these two

Amo

Pimi, there's no fight to be had here — it's family fighting family. Comet is Perplexity's own AI browser, and both Pro plans are US$20/month, down to the penny.

Pimi

Same price, different use. Perplexity is an AI search product in website/app form, Pro billed annually at US$200, about US$16.67/month; Comet is a whole browser — basic features are free with no cap, and Pro adds agent-task credits.

Amo

In other words, if you just want research with cited sources, Perplexity's website version is enough — no need to switch your whole browser; only install Comet if you want AI to operate web pages for you automatically.

Pimi

有個數字我先講在前面，免得被當成我亂降價：Perplexity官網最近幾次查核（8/6、8/8）出現「Pro年繳US$17/月、Max年繳US$167/月」的講法，跟先前記錄的US$16.67／US$167換算數字很接近，應該是同一個年繳價格的不同顯示方式。

Amo

This one checks out for me — the Max plan at US$200/month (US$2,000 billed annually) has the same name on both sides; Comet Max and Perplexity Max should be the same subscription entitlement, since Comet already sits under the Perplexity account system.

Pimi

So the real question isn't "which one to pick," it's "do you want your whole browser to be AI-powered" — subscribe once to Perplexity Pro/Max, and the Pro/Max features in Comet should be shared.

Amo

I've got nothing to argue this time — the official notes at perplexity.ai/comet also state in black and white that Pro/Max subscribers get Comet Plus included for free, confirming it's the same subscription shared across two interfaces, not two separately billed products.

So the conclusion is

Comet and Perplexity are both part of the Perplexity company's product line, with identical pricing for their paid plans: Pro at US$20/month (US$200/year, approximately US$17/month as shown on the official website), and Max at US$200/month (US$2,000/year, approximately US$167/month). Additionally, the Comet Plus plan at US$5/month is included free for Pro and Max subscribers (confirmed by perplexity.ai and comet's official website). The difference lies in the product form: Perplexity is a search website/app, while Comet is a full AI browser with basic functions that have been completely free and unlimited since 2026-03-18, and only agent tasks require Pro or Max quotas. The two can be seen as the same subscription presented in different interfaces, rather than mutually exclusive choices.
