Comet vs Microsoft Edge

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

Microsoft Edge

• Windows users who want Copilot inside the browser
• Comparing options across many open tabs
• People who use Bing, Microsoft Rewards and the Microsoft 365 web apps

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.

Microsoft Edge

• Copilot has usage limits; Microsoft says higher limits, agents and complex multi-step tasks need a Microsoft 365 subscription.
• The iPhone and iPad app lists Microsoft 365 Personal and Premium as in-app purchases, from $9.99.
• Microsoft notes that feature availability varies by device type, market and browser version, and that supported extensions differ between operating systems.
• Password Generator works only when signed in to Edge with password sync turned on.

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.

Microsoft Edge

Copilot in Edge

Copilot sits in the browser to summarize pages, PDFs and videos, answer questions about the page being viewed and compare details across open tabs.

Journeys and the Copilot new tab page

Journeys group related pages, searches and chats so earlier research can be picked up again. The Copilot new tab page takes a question, a search or a web address in one box.

Workspaces and split screen

Workspaces keep sets of tabs separate and color coded, split screen shows two pages side by side in one tab, and tabs can be grouped by topic in one click.

Microsoft Password Manager and passkeys

Password Generator, Password Monitor and Password Health suggest strong passwords, sync them between devices and flag saved credentials found in known leaks. Passkeys are supported too.

Built-in security tools

Microsoft Defender SmartScreen blocks known phishing sites and malicious downloads, a scareware blocker targets fake warnings and support scams, and InPrivate clears history, cookies and form data on close.

Performance and gaming features

Energy saver extends battery life, PC gaming boost cuts the browser's resource use when a game launches, and Edge for Game Bar is an in-game browser for PC gaming.
