# Perplexity

## Identity

An AI-powered search and answer engine. In this workflow, the **Perplexity MCP** is used by [[entity-product-claude-code|Claude Code]] to perform live web research and fact-check information (like the status of GitHub repos) before generating video content.

Canonical: https://www.perplexity.ai/

## Role in the Pipeline

- Backs the fact-checking step described in [[claim-ai-fact-checking]]
- Invoked via [[concept-mcp|MCP]] when [[action-fact-check-prompt|prompted to fact-check]]
- Adds API cost to the pipeline (relevant to [[question-api-costs-scaling]])
