YabComet vs Chrome
Comet is Perplexity’s free Chromium browser for Mac, Windows, iPhone and Android, with Perplexity’s search and an assistant that can act on pages for you.
Chrome is Google’s browser on every desktop and phone, with Gemini built in. Its auto browse agent works in your own signed-in Chrome on a paid Google AI plan, in the US and India.
Both are Chromium with an agent that works in your own signed-in browser. Comet’s is Perplexity’s and has a free tier; Chrome’s auto browse needs Google AI Pro and works only in the US and India.
The short answer
- if you use Perplexity and want its search and agent in the browser
- if you want one AI browser on Mac, Windows, iPhone and Android
- if you want a free Chromium browser with an ad blocker built in
- if you live in Google’s apps and want Gemini across Gmail, Calendar and your tabs
- if you pay for Google AI Pro and want an agent in your own signed-in browser
- if you need the same browser on Mac, Windows, Linux, iPhone and Android
- if you already pay for Claude or ChatGPT and want it to work in your signed-in tabs
- if you want Claude Code, Codex or Cursor to drive a real browser over MCP

Where they differ
What separates them, area by area. Where one plainly has more, it says who; where it comes down to taste, it says so.
AIa matter of taste
Both have an agent that works in your pages. Comet’s assistant answers about pages and open tabs and can click, fill forms and navigate for you, asking before it acts. Gemini chats about your tabs and sums up pages and videos; auto browse clicks, types and fills forms in your own Chrome, on Google AI Pro or Ultra, in the US and India.
Agents like Claude Code and CodexChrome leads
Comet has no MCP server or command line for outside agents. Chrome can be driven over MCP and a command line, through Google’s Chrome DevTools MCP, which starts its own profile unless you let it attach to your Chrome.
Tabs and windowsChrome leads
Comet has Split View, folders in the sidebar and tabs that sleep. Chrome has tabs down the side as a setting, Split View, folders in the sidebar and tabs that sleep.

Where it runsChrome leads

On the phone, Chrome: iPhone, iPad and Android; syncs tabs, bookmarks, passwords and history.
Engine and extensionsa matter of taste
Both are built on Chromium, as Chrome is, so sites work as they do in Chrome. Both take extensions from the Chrome Web Store.
PrivacyComet leads
Comet has an ad blocker built in. Comet keeps history, cookies and passwords on your device unless you sync; the assistant sends the page it needs to Perplexity, kept up to 30 days. Chrome has no ad blocker of its own. Tabs you share with Gemini go to Google; with Keep Activity on, chats are kept 18 months by default and may be reviewed and used to train models.
