AI-native browser with conversational and agentic features

See Perplexity Comet pages and product blog

Summary

Perplexity Comet is a Chromium-based AI browser that integrates Perplexity’s search and conversational AI into the browsing UX. It provides contextual Q&A, grounded citations, and agentic automation (form-filling, email summaries, tab management) via a conversational sidebar.

Features

  • Conversational sidebar with grounding/citations for web content
  • Agentic actions: form-filling, inbox summaries, tab automation
  • Multiple model integrations (Perplexity Sonar/R1 plus optional third-party models)
  • Cross-platform: Windows, macOS, iOS (Android planned)
  • Free tier with paid premium features for advanced automation

Superpowers

Comet is ideal for researchers and power users who want an AI assistant directly integrated into browsing for citation-backed answers and automated workflows.

Pricing

  • Transitioned from an invite-only premium model to a free browser with optional paid tiers for advanced features.

Known limitations & notes

  • Advanced automation features gated behind paid tiers; early versions were invite-only
  • Publisher revenue-sharing and content-citation policies evolving as the product scales

Examples / Practical use cases

  • Example user flows (practical, no installs)
    • Researcher: “Summarize the top 5 announcements from I/O 2025 about AI infrastructure” → Comet returns cards with citations, and a “compare” card that synthesizes differences across announcements. Value: quick briefing with sources.
    • Marketer: “Find 3 case studies of brands using Sora-like video tools for campaigns” → Comet pulls grounded articles and suggests outreach angles. Value: saves hours of tab-hopping.
    • Productivity: “Create a meeting prep card for my 9am with links and suggested agenda” → Comet analyzes Calendar context (if connected), pulls relevant docs, and generates an agenda card.
  • Automations / agentic actions (practical)
    • Example: Summarize my unread email subjects and suggest 3 priority replies — Comet synthesizes suggestions as cards you can open to expand and edit.
    • Value-add: reduces context switching by consolidating discovery and short actions in one surface.
  • Privacy & connector guidance (practical)
    • Keep connectors opt-in for sensitive data; start with Calendar-only experiments to evaluate signal quality.
    • Use the Comet cards as sources for follow-up ChatGPT threads rather than granting broad cross-app access immediately.
  • When to use Comet vs. raw search
    • Use Comet for rapid, interactive research and curated automations.
    • Use raw Search API (Perplexity Search) when you need machine-consumable units or to feed a RAG pipeline with provenance.
