Comet

Comet is Perplexity's browser with an AI assistant built into the chrome itself — it can research across your open tabs, fill out forms, organize your email, and run multi-step browsing tasks on request. It started as an invite-only product and launched free worldwide, with an Android release since extending it past desktop, as Perplexity pushes further into the AI-browser race alongside Arc's successor Dia and OpenAI's own browser ambitions.
