San Francisco-based Perplexity on Wednesday made its new artificial intelligence-powered Comet web browser available to its highest-paying Perplexity Max subscribers and some others.

Perplexity.ai has launched its own Comet browser to take on Google Chrome and Microsoft Edge and their respective search engines. But Comet is enormously expensive, and in tests, didn't always work.

Perplexity’s Max plan with unlimited Labs, early access to features like Comet, top AI models, and priority support for power users.

Reader, it's not cheap. Perplexity Max costs $200 per month or $2,000 a year; the tier down, Perplexity Pro, costs $20 per month or $200 per year. It's the same monthly price as the top tier of OpenAI's offering, ChatGPT Pro; in comparison, the most expensive tier of Google's AI, Gemini, is Google AI Ultra, which costs $249.99 per month.
