Comet browser review โ€” the first mainstream AI-native browser

Comet is Perplexity's Chromium-based browser, rebuilt around the assumption that you never want to 'just browse' โ€” you want answers, summaries, and actions. Every tab can be a chat with the page. An agent mode lets it click, navigate, and fill forms on your behalf. For researchers and knowledge workers, it shortens the loop from query to answer to action.

Who it's for: Researchers, students, and knowledge workers whose day is 40% reading pages they don't need to read. If you spend hours on documentation, news, or spec sheets, Comet cuts the time-to-answer in half.

Key features

๐Ÿค– Per-page chat

Sidebar talks to the current page โ€” summarize, ask follow-ups, extract tables, translate, all without leaving the tab.

๐Ÿ•น๏ธ Agent mode

Give it a task ('book the cheapest flight to Tokyo next Friday') and watch it click, type, and navigate for you.

๐Ÿ“š Session-wide memory

Ask 'compare the three laptops I opened' and it cross-references every relevant tab in your session.

๐Ÿง  Perplexity search built-in

Every new tab is a Perplexity query; citations are embedded by default.

๐Ÿ”’ Ad & tracker blocker

Chromium-grade ad blocking with AI-readable page cleanup for cleaner extraction.

๐Ÿช„ Cross-device handoff

Start on phone, continue on desktop โ€” conversations and tabs follow you.

The honest take

โœ“ What works

  • Genuinely useful โ€” I replaced 90% of my Google+Wikipedia+Reddit research loops
  • Agent mode works on real tasks (flight search, form fill, shopping)
  • Sidebar chat is the single best UX feature of any browser extension, made first-class
  • Chrome extension import makes switching painless
  • Perplexity Pro features included at $20/mo, cheaper than buying each separately

โœ— What doesn't

  • Chromium โ€” vertical-tab & power-user extension setups from Arc/Firefox need re-platforming
  • Agent mode still occasionally stalls on complex cookie-wall sites
  • All processing is cloud-side; not for high-confidentiality use cases
  • Mobile app is iOS-only at this writing (Android in beta)

Verdict

Comet is the first browser in years that made me reconsider what a browser is for. It's not 'Chrome with a chatbot' โ€” the sidebar-per-tab model and agent mode genuinely change how you research. It won't replace a privacy-hardened browser for sensitive work, but for day-to-day knowledge work it's the new default. Highly recommend for anyone whose job is reading-and-deciding.
