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. Copilot reads the page, your tabs and history and sums up videos and PDFs; Browse with Copilot scrolls and types in pages for you, signed in, on Microsoft 365 Premium in the US.

Agents like Claude Code and CodexEdge leads

Comet has no MCP server or command line for outside agents. Edge can be driven over MCP and a command line, through Microsoft’s Playwright MCP, which can launch Edge or attach to your running Edge.

Tabs and windowsEdge leads

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

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.

Privacyeven

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. Edge has a VPN.
