Comet by Perplexity

Comet by Perplexity is an AI-native research and analysis environment designed for teams that work with complex information at scale. It combines a powerful large language model interface with structured workspaces, enabling users to investigate topics, compare sources, and document findings in a single, organized hub. With Comet, teams can create shared projects, break research into threads, and attach citations directly to AI-generated outputs, ensuring traceability back to original sources.

The tool supports iterative questioning, allowing users to refine prompts, branch lines of inquiry, and preserve the full context of an investigation over time. Key capabilities include collaborative research boards, source-linked summaries, cross-document synthesis, and the ability to manage long-running research efforts without losing prior work. Typical use cases include market and competitive analysis, technical due diligence, policy and regulatory research, academic-style literature reviews, and internal knowledge consolidation.
