Perplexity's Comet AI browser is now available as a standalone app for iPhone users.
The tool initially debuted last summer on PCs, but cost $200 a month .
The new app is free, as is the recently-released Android version .
Comet is an AI-powered browser, which has become a hot product category throughout the past year or so .
This is basically a web browser combined with a chatbot that can perform some tasks on a user's behalf.
Like related tools, people can ask it to summarize a webpage or conduct additional research for more context about a subject.

The company boasts that folks can use the tool to shop and make schedules.
I advise some caution for both of these tasks, given that AI browsers are notorious marks that easily fall for various online scams .
