Comet: a browser with intent.

Comet is Perplexity's biggest 2026 play — a full agentic browser on iOS, Android, Mac, and Windows, now powered by Claude Opus 4.6 underneath. It isn't "Chrome with AI bolted on." It's built on the premise that you usually want to do something with a page, not just read it. The new skill is steering an agent that can act — and knowing where to make it stop.

The mental model

A browser that does, not just shows.

A normal browser hands you a page. Comet treats the page as something to act on — summarize it, compare it, fill it, or chain it into a multi-site errand — and it can reach your inbox and calendar with permission.

🌐 Normal browser

Loads pages. You read, tab-switch, copy-paste, and do the work yourself.

☄️ Comet

Loads pages and acts on them — ask the page, run a multi-site task, bridge to email/calendar. You supervise.

Do it · ask the page

Question the page you're on.

The simplest Comet pattern: while reading anything, ask Comet about it — no tab-switching, no copy-paste. Try a few in-page queries.

What the four-day-week trials actually found

Across 2022–2025 pilots in the UK, Iceland, and Japan, most participating firms kept output flat or higher while cutting hours about 20%. Reported burnout fell and attrition dropped at the majority of sites…

But the trials skewed toward white-collar, knowledge-work firms that opted in. Shift-based and customer-coverage roles were underrepresented, and few studies ran a true control group…

☄️ Ask this page
Now you're on a different page — a vendor contract you're about to sign. Comet offers a summary. What do you do?
Read the original. Comet's summaries are strong but can miss nuance. For high-stakes content — contracts, legal, medical — use the summary to orient, then read the actual text. The cost of a missed clause is far higher than the minutes saved.
Do it · steer the agent

Where should Comet stop and ask?

Comet's real power is autonomous, multi-site tasks: state an outcome, it plans and executes. The safety rule is that it pauses for confirmation before anything irreversible. Here's its plan — tap the one step where it should stop and ask you first.

☄️ Comet · autonomous task
"Find the cheapest MSP→SFO flight, Friday morning out, Sunday evening back. I'll check before booking."
Which step needs your confirmation?
Do it · grant the right access

Give it only the access the task needs.

Comet bridges browser and inbox with permission tokens. Match the scope to the job — read-only wherever that's enough, write access only for what you actually want it to change.

About Comet

Comet launched globally to iOS users in 2026, joining Android, Mac, and Windows, and now uses Claude Opus 4.6 underneath. It also has agentic browsing integrated into Samsung Internet, and Perplexity is available as an optional default search engine on Samsung devices.

Challenge: switch to Comet for one week

Install Comet on your main device and use it as your default browser for a week. By day four the in-page queries and autonomous tasks become habit. Notice which workflows got dramatically easier — and which still pull you back to Chrome or Safari. Audit the permissions you granted and trim them.

What you can do now

  • Use in-page queries instead of tab-switching for research
  • Read the original for high-stakes content — don't trust the summary alone
  • Run autonomous multi-site tasks, with confirmation before anything irreversible
  • Connect email and calendar for cross-system patterns
  • Grant the minimum scope — read-only unless write is truly needed
