Lesson 05 · Perplexity Mastery Pro ~10 min read 3 workflows + privacy

Comet: AI in your browser.

Comet is Perplexity's browser — an AI-native replacement for Chrome where Perplexity is built into every tab. This lesson covers what changes when AI lives in your browser, the three workflows that justify the switch, and the privacy considerations of an AI that sees everything you do online.

The mental model

A browser with AI built in is a different category than a browser with AI as a tab.

When AI can see what's on your screen, it can summarize, compare, and act on pages without you copying anything in. The win is the friction reduction. The trade-off is privacy — Comet sees a lot.

Workflow 01 Tab-aware summaries

1

Summarize any page in one click

Reading a long article, doc, or report? Comet's sidebar AI summarizes the current tab on demand.

The prompt that works

Use patternOpen any long page → click the Comet AI button in the sidebar → "Summarize this in 5 bullets." / "What's the main argument?" / "What does this skip over?"

Best use cases

  • Long-form articles and essays
  • Industry reports and whitepapers
  • Forum threads and discussions
  • Technical documentation
Comet AI summaries can miss nuance on highly technical or argumentative content. For anything you'd quote externally, read the actual source.
Time savings: 30-min read → 90 sec summary.

Workflow 02 Cross-tab queries

2

Ask questions across multiple tabs

Have 5 tabs open comparing options? Ask Comet questions across all of them.

The prompt that works

Cross-tab promptsCompare these 5 product pages I have open. Which has the best refund policy? Across these 3 articles I have open, what's the most common explanation for [phenomenon]?

Best use cases

  • Product comparisons before purchase
  • Research synthesis across open tabs
  • Reconciling conflicting information
  • Side-by-side analysis
Cross-tab queries depend on Comet seeing all your tabs. Privacy-sensitive: don't use cross-tab features while logged into anything sensitive.
Time savings: Manual cross-tab comparison: gone.

Workflow 03 In-browser agent actions

3

Have Comet do things in the browser

Comet can take simple actions in your tabs — fill forms, click buttons, navigate.

The prompt that works

Action promptsFill this form using my saved profile. Visit the next 5 search results and tell me which ones mention [topic]. Book a table at [restaurant] for Saturday at 7pm.

Best use cases

  • Routine multi-step web tasks
  • Research across many pages
  • Form filling with context awareness
Browser-acting AI is powerful and easy to misuse. Don't let Comet act on anything important without supervising. Banking, healthcare, anything irreversible — handle manually.
Time savings: Repetitive web tasks: automated under supervision.

Final challenge: spend a workday in Comet

Install Comet. Use it as your default browser for one workday. Track when the AI actually helped vs. when it just got in the way. Decide if it's worth the privacy trade-off based on your real usage.
