Introduction
OpenAI’s ChatGPT has become the de‑facto conversational AI for millions of users, offering a web‑based chat interface, mobile apps, and a growing ecosystem of paid plans that unlock higher message limits, larger context windows, and advanced reasoning models.
Perplexity positions itself as an AI‑powered search engine that returns cited answers, orchestrates multiple large‑language models, and adds deep‑research capabilities for decision‑making workloads.

Quick Verdict
Company & Background

| Perplexity | Founded in 2023, Perplexity markets itself as an AI‑augmented search engine that provides real‑time cited answers. The platform emphasizes multi‑model orchestration (GPT‑4, Claude, Sonnet, etc.) and deep‑research reports for professional use cases. |
