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.
