Comet
Perplexity's AI browser with an assistant that acts across tabs
What is Comet?
Comet is an AI-powered browser from Perplexity with a built-in assistant that summarizes pages, answers questions about open tabs and carries out assigned tasks such as shopping, scheduling and research. The mobile apps add a voice mode for talking to the assistant, summaries across all open tabs and a built-in ad blocker. The browser is free to download, and Perplexity Pro and Max subscriptions are sold inside it as in-app purchases.
Comet has a free plan. Paid plans start at $20.00 (lowest Perplexity Pro in-app purchase; billing basis not shown). See every plan
Good for
- People who want an assistant to carry out multi-step web tasks
- Summarizing research spread across many open tabs
- Perplexity subscribers who want its AI search inside the browser
Worth knowing
- The App Store lists Perplexity Pro at $20.00 and $200.00 and Perplexity Max at $200.00 as in-app purchases, without stating a billing period.
- Google Play lists in-app purchases from $4.99 to $249.99 per item, and neither store says which features or limits depend on a paid plan.
- Perplexity's website could not be read when checked, so Mac and Windows availability comes from press coverage rather than a vendor page.
Key features
- Comet Assistant
- A built-in assistant takes on assigned tasks such as shopping, scheduling and research. Its actions are shown as it works, and the user can step in at any time.
- AI search with page context
- AI search is built into the browser and uses the context of the page being viewed, so questions can be asked and answered without leaving the site.
- Summaries across tabs
- Smart summarization condenses content from all open tabs at once, not only the page currently on screen.
- Voice mode
- On mobile, voice mode lets a person talk to the assistant to find information across the tabs they have open.
- Built-in ad blocker
- An ad blocker removes spam and pop-up ads on mobile as on desktop, with a whitelist for sites the user trusts.
