Perplexity
Perplexity is the AI company behind the answer engine of the same name and the
Comet AI browser. In this spoke it appears as a browser maker — Comet is
its move to own the browsing surface, not just the answer box. Its answer-engine / AI-search
business is ../search-marketing-wiki and ../llm-providers-wiki territory (cross-link there); here
the relevant fact is that an AI-search company built a browser, betting the browser is where its
assistant should live.
