Perplexity AI
Auto-generated score, not yet verified against the scoring model. Under review — treat as indicative, not a verdict.
Summary
Perplexity AI is a San Francisco-based AI 'answer engine' and, since 2025, an AI-powered web browser called Comet, valued at roughly $20-23 billion as of early 2026. The company faces a large and growing number of copyright and trademark lawsuits from major publishers (Dow Jones/New York Post, The New York Times, Chicago Tribune, Encyclopaedia Britannica/Merriam-Webster) and platforms (Reddit, Amazon) alleging unauthorized scraping, content reproduction, and covert automated access, alongside independent security research documenting serious prompt-injection vulnerabilities in its Comet browser. No crypto-specific scam activity by the company itself was found, though its brand name is a plausible target for unaffiliated token-impersonation scams common across the AI sector.
