Fabrica vs Comet.
Perplexity's AI-first browser
Comet is a standalone browser shipped by Perplexity, with AI search and AI actions built in. Fabrica Control is a Chrome extension — it adds an agent to the browser you already use, instead of asking you to switch browsers. Different bet on the user: Comet replaces your browser, Fabrica augments it.
How is Fabrica different from Comet?
Should I pick Fabrica or Comet?
You already love Perplexity, you are willing to make Comet your primary browser, and you want AI search built into the address bar.
You want to keep using Chrome (or Brave / Arc / Edge), keep your existing extensions, and add a real agent that operates your tabs without changing browsers.
What are Comet's strengths and trade-offs?
- +AI is native to the browser — no extension layer to manage
- +Tightly integrated with Perplexity search and Perplexity Pages
- +Polished consumer-grade UX
- +Free entry tier
- −Requires switching primary browser — significant adoption friction
- −Tied to the Perplexity ecosystem, not LLM-agnostic
- −Less mature agent capabilities than purpose-built agent products
- −Loses Chrome's extension ecosystem unless features are reimplemented
Common questions about Fabrica vs Comet.
No. Fabrica installs as a Chrome extension and works in any Chromium-based browser (Chrome, Brave, Arc, Edge). You keep your existing browser, your existing extensions, your existing logins.
Comet and Fabrica are adjacent but make different bets. Comet bets users will switch their primary browser to get AI features. Fabrica bets users will install one extension to add an agent to the browser they already use.
Fabrica is purpose-built around the AGAS premise — skill memory, multi-tab orchestration, no-API automation across 1,000+ tools. Comet's strength is AI search and address-bar AI rather than deep agent orchestration.
