In a bold challenge to tech giant Google, Perplexity CEO Aravind Srinivas has unveiled his vision for the Comet browser, claiming it can outperform Google’s internal AI browser project, Project Mariner. In a recent Reddit AMA and podcast appearances, Srinivas described Comet as a user-first...

Why Comet Is Different

Built on Chromium, but designed to be an AI-native browser
Integrates deeply with tools like Gmail, Google Calendar, and LinkedIn
Performs complex tasks like recruitment workflows, email scheduling, and meeting prep
Functions like a digital operating system, running background processes from natural language prompts

Srinivas emphasized that Comet is not just a chatbot or search engine—it’s a proactive assistant that understands user intent and executes tasks autonomously.

Taking on Google’s Project Mariner

Project Mariner is reportedly available only to Google’s $250/month subscribers
Srinivas called it “similar but quite limited” compared to Comet’s capabilities
Criticized Google’s ad-driven business model as a barrier to true AI innovation
Warned that Google may eventually copy or adopt Comet’s features, but lacks the agility to lead

“It’s a giant bureaucratic organization with too many decision-makers,” Srinivas said. “They need to embrace one path and suffer, in order to come out stronger.”

Disrupting the Workplace

Srinivas claims Comet could replace roles like recruiters and executive assistants
Automates sourcing, follow-ups, calendar syncing, and briefing tasks
Envisions Comet as a personal OS for professionals, streamlining workflows and saving time
