Comet

What it does

Comet puts an assistant in the browser chrome: ask about the page you are on, compare several open tabs, or have it summarise a supplier catalogue while you keep scrolling. Answers link back to the pages they came from.

It is most useful for research-heavy work — competitor checks, product comparisons, reading long terms of service. It is still a browser, so anything involving a login or a payment deserves your full attention.

Standout features

• Sidebar answers about the current page
• Compare and summarise multiple tabs
• Citations back to source pages
• Assistant actions inside the browser

Main job: read the pages you already have open and answer questions with links back to them.

Best for

Use it for supplier or competitor research across many open pages, when you want a cited answer without copying URLs into a separate chat tool.

Getting started

Open the pages you want to compare, click the assistant icon in the sidebar, then ask a question about the current tab or across all open tabs. Follow the citation links before trusting a number.

Watch out for

Watch out: browser assistants can see whatever is logged in on that profile. Do not let it act on banking, checkout or password pages, and check the provider's data-retention terms for customer material.
