Comet vs Google Chrome

Comet

• 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

Google Chrome

• Google Account users who want the same bookmarks, passwords and tabs on every device
• People who depend on extensions from the Chrome Web Store
• Those who want Gemini and Google's AI search inside the browser

Comet

• 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.

Google Chrome

• Auto browse, where Gemini carries out multi-step tasks, is available only to Google AI Pro and Ultra subscribers in the U.S.
• Gemini in Chrome needs a signed-in, eligible account in a supported country, and Google's FAQ says it is not available on Android yet.
• Enhanced Safe Browsing requires browsing data to be sent to Google.
• Desktop requirements start at Windows 10, macOS 13 Ventura, and 64-bit Ubuntu 18.04, Debian 10, openSUSE 15.5 or Fedora Linux 39.

Comet

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.

Google Chrome

Tab groups, vertical tabs and split view

Tabs can be grouped, labeled and color coded, stacked down the side of the window as vertical tabs, or shown two at a time in split view.

Sync across devices

Signing in to Chrome brings bookmarks, saved passwords, payment info and open tabs to any phone, tablet or computer, and a tab can be sent from one device to another.

Google Password Manager and passkeys

Google Password Manager is built in to save, manage and generate passwords. Passkeys allow sign-in with a fingerprint, face, PIN or pattern.

Safe Browsing and Safety Check

Safe Browsing warns before a dangerous site or download, with an optional enhanced mode. Safety Check reviews saved passwords, extensions and settings and points out anything that needs attention.

Gemini in Chrome and AI Mode

Gemini in Chrome answers questions using the context of open tabs, and Skills save prompts for reuse. AI Mode, Google's AI search, accepts tabs, files and images as context.

Extensions and performance controls

Extensions from the Chrome Web Store add features, Energy Saver and Memory Saver limit resource use, and Google ships a new Chrome update every four weeks.
