Comet vs Brave

We make Yab, the third column.facts checked Oct 9 ↓

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.

Brave is an open-source Chromium browser that blocks ads and trackers by default, with Leo, an AI chat that needs no account, on every desktop and phone.

The short answer

Pick Comet
  • 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
Pick Brave
  • if you want ads and trackers blocked by default
  • if you want AI chat without an account, or on your own local model
  • if you need the same browser on every desktop and phone
Or Yabours
  • if you already pay for Claude or ChatGPT and want it to work in your signed-in tabs
  • if you miss Arc and want spaces, pins and folders kept, on a Mac

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.

AIComet leads

Only Comet has an agent that clicks, types and finishes tasks 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. Leo chats about your tabs, PDFs and images, with no account, on Brave’s models or your own; an agent is in early testing behind a flag, in a separate profile without your sign-ins.

Tabs and windowsBrave leads

Comet has Split View, folders in the sidebar and tabs that sleep. Brave has tabs down the side as a setting, Split View, folders in the sidebar and tabs that sleep.

Priceeven

Comet: Free; Comet Plus $5/month; Perplexity Pro $20/month or Max $200/month for more AI and agent use. Brave: Free, with Leo; Leo Premium $14.99/month; Brave VPN $9.99/month.

Where it runsBrave leads

Comet runs on Mac, Windows, iPhone and Android. Brave runs on Mac, Windows, Linux, iPhone and Android. On a Mac, Comet needs macOS 13 or later and Brave needs macOS 13 or later. On the phone, Comet: iPhone, iPad and Android; on iPhone it syncs bookmarks and history with desktop Comet. On the phone, Brave: iPhone, iPad and Android; syncs tabs, bookmarks, passwords and history, no account.

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.

PrivacyBrave 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. Brave has an ad blocker built in, a VPN and open code. Brave says Leo doesn’t keep or share chats, doesn’t train on them and doesn’t collect identifiers like IP addresses.

What their pages don’t lead with

Real limits, from the makers’ own words and our own use.

Perplexity Comet

  • Free use of the assistant is limited; more agent use is Pro at $20 or Max at $200
  • No MCP server or command line from Perplexity for coding agents
  • Researchers showed prompt-injection attacks on its agent in 2025 (CometJacking)

Brave

  • More Leo models and higher limits need Leo Premium at $14.99 a month
  • Its AI agent is an early test behind a flag, without your sign-ins
  • The VPN is $9.99 a month extra
  • Tabs down the side are a setting, and there are no spaces

Yab, honestly

  • Mac only: macOS 15.4 or later, no Windows, iPhone or Android
  • New: first released in September 2026
  • Its AI needs a Claude or ChatGPT plan; ChatGPT’s free plan may work with low limits
  • WebKit, as in Safari: a site tested only in Chrome can misbehave
  • Closed source
