Introduction
The AI chatbot landscape is constantly evolving, with tools like ChatGPT and Perplexity AI leading the way. While they may seem similar at first glance, these two AI-powered platforms serve different purposes. ChatGPT is a general-purpose AI assistant designed for various language-based tasks, whereas Perplexity AI focuses on providing up-to-date, accurate information in a search engine-like manner.
This article provides a comprehensive comparison of Perplexity AI and ChatGPT, highlighting their key features, strengths, and which one you should choose based on your needs.
Overview
Perplexity AI is designed as an AI-powered search engine that leverages large language models to fetch real-time information from the internet while citing sources for credibility. It focuses on providing precise, up-to-date answers with references.
ChatGPT, developed by OpenAI, is a conversational AI model known for generating human-like text. It is widely used for content generation, problem-solving, coding assistance, and general conversation but does not fetch live internet data in real-time unless integrated with a browsing feature.
