Analysis

ChatGPT-User browses the web in real-time when ChatGPT users ask questions requiring live data, while PerplexityBot builds a persistent search index for Perplexity's answer engine. ChatGPT-User has higher volume due to ChatGPT's massive user base, but each PerplexityBot visit feeds a persistent index with longer-lasting visibility.

Both cite your content with source links, making them valuable for content discoverability. ChatGPT-User visits are ephemeral (one conversation), while PerplexityBot indexing persists across all Perplexity users.
