Comet vs Safari

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.

Safari is Apple’s browser for Mac, iPhone and iPad, on WebKit, with Apple Intelligence for summaries and tab topics. Safari 27 also lets outside agents like Claude Code drive it over MCP.

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 Safari

if you use a Mac and an iPhone and want your tabs and passwords on both
if you want AI that runs on your Mac or on Apple’s Private Cloud Compute
if you build sites and want Claude Code or Codex to test them in WebKit

Or Yabours

if you miss Arc and want spaces, pins and folders kept, on a Mac
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.

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. Apple Intelligence sums up pages, sorts tabs into topics and watches a page for price drops, and the Passwords app can change weak passwords for you; no agent that works through sites.

Agents like Claude Code and CodexSafari leads

Comet has no MCP server or command line for outside agents. Safari can be driven over MCP, through safaridriver --mcp in Safari 27, once you allow remote automation and outside agents.

Tabs and windowsComet leads

Comet has Split View, folders in the sidebar and tabs that sleep. Safari has spaces.

PriceSafari leads

Comet: Free; Comet Plus $5/month; Perplexity Pro $20/month or Max $200/month for more AI and agent use. Safari: Free with macOS; Apple Intelligence is free on Macs with M1 or later.

Where it runsComet leads

Comet runs on Mac, Windows, iPhone and Android. Safari runs on Mac and iPhone. On a Mac, Comet needs macOS 13 or later and Safari needs macOS 15 or later. On the phone, Comet: iPhone, iPad and Android; on iPhone it syncs bookmarks and history with desktop Comet. On the phone, Safari: built into iPhone and iPad; syncs tabs, bookmarks, history and passwords via iCloud.

Engine and extensionsa matter of taste

Comet is built on Chromium, as Chrome is; Safari on WebKit, the engine Safari uses. Comet takes extensions from the Chrome Web Store, Safari from the App Store, as Safari extensions.

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. Safari has no ad blocker of its own. Apple Intelligence runs on the Mac or on Private Cloud Compute, which Apple says doesn’t store what you ask or make it accessible to Apple.

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)

Safari

Apple devices only
Tabs only across the top, and no Split View of two tabs
Extensions only from the App Store, in Safari’s format
Its AI needs a Mac with M1 or later and macOS 27

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

Claude Code, Codex and any MCP client can drive it too. It runs on WebKit, the engine Safari uses, and takes Chrome extensions. It is Mac only, and new.
