Perplexity launches Comet: The quiet new player in the AI browser wars

Just when you thought the AI browser saga was already spicy enough with OpenAI’s big headline-grabbing move, here comes Perplexity sliding in with a stealthy uppercut. The AI search startup, backed by Nvidia and now flush with cash, has also just officially launched its own AI-powered browser, Comet. Clearly, everyone is raring to rain on Google Marketing Live 2025's parade.

While OpenAI’s upcoming browser drop feels like a headline act at Coachella, Comet is more like an intimate indie gig at present: smaller, invite-only (for now), and targeted at paying Perplexity Max subscribers, who pay $200 a month. But don’t let the size fool you; the ambition is just as bold.

Again built on Chromium, like it future Open AI and current Google competitors (because why reinvent the wheel when you can remix it?), Comet offers a sidekick AI experience designed to do more than just summarise search results. It can book hotels, compare flights, manage tabs, fill out forms, even help you send emails; basically, it wants to be the hyperactive multitasking buddy you didn’t know you needed.

Comet isn’t merely an overlay or an assistant perched awkwardly on your browsing sessions. It’s an "agentic" AI that aims to take action on your behalf, echoing the same philosophy behind OpenAI’s Operator agent. While Operator wants to be your all-in-one concierge, Comet positions itself as the ultimate productivity enabler which is still willing to show you options rather than making decisions for you wholesale. Think less controlling butler, more caffeinated executive assistant.

Perplexity CEO Aravind Srinivas is pitching Comet as a new interface for the modern web, emphasizing transparency and privacy (local data storage is a big selling point here). This might win over privacy-conscious users who shiver at the thought of handing over every click to big tech overlords.

Just to keep the record straight: Perplexity isn’t playing corner-pocket with OpenAI; it’s packing an absolute arsenal. As of July 9, 2025, the Nvidia-backed startup is in late-stage talks to raise a further US $500 million at a valuation north of US $14 billion, up from $9B in December of last year. That’s a jaw-dropping 27-fold increase in less than 18 months, giving it enough investor confidence (and cash) to make Comet more than a boutique experiment. Now it’s a credible challenger in the AI browser wars.

The timing? Classic. With OpenAI’s browser story detonating just before Google Marketing Live, Comet’s launch feels like an opportunistic side plot in a summer blockbuster, in a move to grab mindshare while Google and OpenAI exchange fire in the main arena.

If OpenAI’s browser is gunning straight for Google’s search and ad empire, Comet is quietly carving out a niche for people who still want to see the web; just faster, cleaner, and smarter.

As the AI browser wars heat up, one thing is clear: the era of passively clicking through pages is rapidly closing. Whether you want an aggressive overlord (OpenAI) or a polite helper (Perplexity), the AI is officially at your fingertips. Choose your agent wisely.
