Perplexity Comet

What it is

Comet is Perplexity's agentic browser. You give it a goal (research a competitor, fill out a form, book a flight) and it navigates, clicks, and fills inputs across real websites — staying inside the same browser session you'd use yourself.

Notes from using it

What makes Comet feel different from every other agentic browser is that it lives inside *your* browser session. Cookies, logins, autofill — everything you've already authenticated to comes along, which collapses 80% of the friction other browser agents create. For research workflows that span multiple authenticated sites, it's genuinely fast.

Reliability still falls off on long, branching tasks. "Research these five competitors and synthesize" works; "book this complex multi-leg flight" usually doesn't. The pattern is the same as every other browser agent in 2026: transactional flows are a coinflip, research flows are reliable.

The lock-in to consider: Comet is a Perplexity-flavored Chromium fork. It's pleasant to use as your main browser, but you're committing to Perplexity's tab/window model, their privacy posture, and their update cadence. Switching back to vanilla Chrome later is a real lift.

Where it shines

• Lives inside a real browser, so it inherits your logged-in sessions.
• Tight coupling with Perplexity search makes research workflows fast.
• Lower friction than headless agent platforms — feels like a sidekick.

Where it falls down

• Browser is the surface — no headless API for production workflows.
• Reliability on long, multi-step tasks still uneven.
• Locks you into Perplexity's Chromium fork.
