What this tool does well
Comet is Perplexity's browser, available on desktop and mobile. Its assistant can help explain pages and compare information while you browse. Supported agent features can also take actions, subject to account access and permissions.
You can browse and try basic AI features without a Perplexity account. Signing in unlocks further capabilities. The free browser and paid Browser Agent access are different things, so check the plan rather than assuming installation enables every action.

Who this tool suits
This suits someone comparing services, reading documentation or collecting evidence from several tabs. Begin with public pages and ask for a comparison that links each claim to the page it came from.
Keep the job read-only for your first test. Open the cited passages and check whether they support the comparison. If a page is inaccessible or the assistant cannot read it, require it to say so instead of filling the gap.

What to watch for
A browser assistant can work close to signed-in accounts and private information. Review what it may access, and do not give it permission to send messages, buy items or change records just to summarise a page.
Webpages can contain misleading instructions as well as inaccurate facts. Treat their content as information to check, not authority to change the task. Advanced assistant limits and workplace restrictions can differ by plan and organisation.

Try this task
Compare three public pages in Comet, keeping the task read-only, and verify the source behind each important difference.
Try this prompt
Compare these open public pages for [decision]. List the main differences and link each important claim to its source page. Mark inaccessible pages and uncertain information. Read only: do not sign in, fill forms, send messages, buy anything or change settings.
Skip it if
You cannot review browser permissions or need to handle sensitive signed-in pages without an approved setup.
What to check before paying
Check the current Perplexity plan's Browser Agent allowance, supported device features and workplace restrictions. Basic browsing is free; advanced actions are not the same entitlement. Review data access before connecting personal or business accounts.

Comet is worth testing as a reading and comparison assistant before delegating actions. The useful result is a summary whose sources you can check without losing track of the original pages.
