Perplexity is expanding its AI browser Comet to Windows users through a selective testing program, following its initial macOS beta launch in May. This development comes amid reports that Apple executives are considering acquiring the AI search company for what could be Apple’s largest acquisition ever at $14 billion.

What you should know: Comet is a Chromium-based browser that replaces traditional search engines with Perplexity AI’s conversational search experience.

  • The browser provides curated responses to queries similar to Google’s AI Mode, complete with source links and product purchase options.
  • Built-in features include an ad blocker, page summarization, and an Ask Button that provides context about all open web pages.
  • A Gmail connector enables users to ask questions about their emails and calendars directly through the browser.

Key details: CEO Aravind Srinivas announced the Windows testing phase is now underway for select invitees, with mobile versions planned next.

  • “Android build is also moving at a crazy pace and moving ahead of schedule. iOS updates soon,” Srinivas said on Sunday.
  • The macOS beta added a “try-on” feature for clothes, where the browser generates images of users wearing selected outfits.
  • Interested users can join a waitlist, though Perplexity hasn’t announced an official release date.

The big picture: The browser launch coincides with Apple’s reported interest in acquiring Perplexity as the iPhone maker seeks to catch up in AI development.

  • Bloomberg reports that senior Apple executives have discussed acquiring Perplexity AI, which is currently valued at $14 billion.
  • Apple has fallen behind competitors in AI development, facing feature delays and legal challenges.
  • If completed, the acquisition would represent Apple’s largest purchase in company history.

Why this matters: Comet represents a direct challenge to Google’s search dominance by embedding AI-powered search directly into the browsing experience, while the potential Apple acquisition could dramatically reshape the AI search landscape.
