# Perplexity

## Profile

Perplexity is a search-focused AI product (Perplexity AI) referenced in this source as another example of a tool that benefits from the [[concept-honing-effect]].

## Role in the Source

[[entity-nate-b-jones]] notes that if you use Perplexity enough, it adapts to your cognitive pathways, creating the same lock-in dynamics seen in [[entity-chatgpt-d18]] and [[entity-claude-d18]]. It is included to demonstrate that the honing effect is **platform-agnostic** — any AI with persistent memory will produce it.
