OpenAI revolutionized artificial intelligence, paving the way for tools like ChatGPT and Perplexity AI to reshape how we interact with technology. While both stem from GPT technology, their distinct approaches make them worth comparing for anyone seeking the best AI assistant.

1. Technology

The language models differ notably between ChatGPT and Perplexity. ChatGPT's free version offers GPT-4o mini with limited access to features like data analysis and web browsing, while the $20/month Plus plan unlocks more models (GPT-4, GPT-4o, OpenAI o1-preview) and tools like DALL-E for image generation and advanced voice mode.

Perplexity Pro, also $20/month, uses models like GPT-4 Omni and Claude 3.5 Sonnet for advanced tasks, offering up to 300 Pro Searches daily. It supports file analysis (e.g., PDFs) and includes $5 monthly API credit for embedding AI search in custom projects. Pro users also get access to dedicated support channels.

2. Functionality

ChatGPT and Perplexity are conversational AI tools, but they differ in functionality due to a difference in design philosophy. ChatGPT is more of a traditional AI chatbot, but the ChatGPT Plus version takes it further. You can create and design a team of Custom GPTs for almost any use. With ChatGPT now integrating a web search feature, you can get up-to-date information with the advanced reasoning provided by the GPT-4o models, with the added benefit of sourcing within the response.

Perplexity AI is more similar to a search engine that provides suggestions and sources in response to your queries. It is designed to search the web in real-time to provide up-to-date information on various topics. The related search queries at the bottom of a response are very helpful when diving deeper into a subject and let you get stuck into a rabbit hole if you want.

While both tools are great for research and information retrieval, ChatGPT's expanded functionality suits users looking for a comprehensive tool. Perplexity, meanwhile, shines as a specialized, real-time answer engine for trusted, no-frills information.

3. Pricing

Perplexity and ChatGPT offer competitive pricing for their premium plans, each costing $20 monthly. While this price point grants access to advanced features, the two platforms cater to different needs.

ChatGPT Plus provides expanded access to OpenAI's GPT-4 and its variants, alongside priority access to new features, data analysis, file uploads, and enhanced tools such as Advanced Voice Mode. It's designed for users who rely on advanced conversational AI capabilities to boost productivity and streamline tasks.

Perplexity Pro, on the other hand, emphasizes advanced search functionalities with at least 300 Pro Searches daily, file analysis capabilities, and access to cutting-edge AI models like GPT-4 Omni and Claude 3. Additionally, it includes a $5 monthly API credit for embedding AI into custom projects, making it an attractive option for developers and researchers. Perplexity also offers more community-driven support, such as a dedicated Discord channel for Pro users and prioritized customer support.

If you're weighing up these options, the choice largely depends on how you use either tool. ChatGPT Plus excels at providing a polished conversational AI experience for tasks like writing and analysis, while Perplexity Pro shines in scenarios requiring advanced search tools and customizable AI models. Both platforms offer free versions, allowing you to test features before committing to a subscription. ChatGPT Plus is still well worth the money, and Perplexity AI can make the searching experience intuitive and enjoyable.

4. Responses

To compare the performance in terms of responses, we conducted a series of tests between the two chatbots, presenting the same questions to both language models.

The tests revealed that ChatGPT Plus consistently provided quicker and more straightforward responses.

Perplexity produced responses of excellent quality, but it was slower. If you want logic broken down and lots of sources, Perplexity is a perfect search companion. However, while the answers might not be elaborate, they are accurate. You'll often find that Perplexity is great at finding sources that help you find the right answers.

5. Supported Platforms

ChatGPT Plus has a paid version and a massive user base, most of whom access ChatGPT through the web interface or a desktop app for Windows or Mac. You can try using ChatGPT from your iOS or Android device, and there is now an official ChatGPT iOS app. The advanced voice mode available to ChatGPT Plus members has some incredible uses as well, making it seem like you are talking to a real person.

Perplexity is also available online and as an app for iPhone and Android users. This means you can easily access one of the most powerful search engines straight from your pocket. The Perplexity app also boasts a voice command feature that allows you to send prompts hands-free, with amazing results.

6. Speed and Stability

Perplexity AI is renowned for its speed, thanks to its real-time web search capabilities, which deliver up-to-date information in seconds. It's a top choice for quick fact-checking or keeping up with breaking news.

ChatGPT, with its new live search feature, has closed the gap. The GPT-4o model, available to Plus subscribers, provides fast and natural-feeling responses. While Perplexity excels in rapid data retrieval, ChatGPT now offers comparable speed with added versatility for engaging, in-depth conversations.

Both platforms are reliable. ChatGPT prioritizes access for Plus users during peak times, while Perplexity's smaller user base ensures steady performance as long as you're online.

7. Comparison With Copilot (formerly Bing Chat)

Copilot, integrated into Microsoft Edge and Windows, is designed for seamless productivity. Its Bing-powered search delivers quick, relevant results alongside tools like image generation, voice commands, and file handling. This tight integration makes it ideal for users embedded in the Microsoft ecosystem, offering a streamlined browsing and research experience.

In contrast, ChatGPT excels in versatility and creativity with advanced tools like customizable GPTs and continuous voice interaction. Its new live search feature enhances real-time capabilities, while Perplexity focuses on delivering accurate, well-cited information through real-time web searches. Perplexity's strengths lie in research and fact-checking, making it a trusted choice for up-to-date information. Your choice depends on whether you value integration, flexibility, or precision.

ChatGPT Plus vs. Perplexity AI: Two Impressively Different Chatbots

Both ChatGPT Plus and Perplexity offer unique features and advantages if you want to elevate your writing, coding, or research projects. While ChatGPT Plus is more versatile and can be used as an overall AI companion, Perplexity is perfect for researching any topic.

While both are worth trying out, ChatGPT Plus does have a slight edge here because of the support for plugins and other features. You also get access to more prompts ChatGPT, though you can expect Perplexity to continue improving. I personally keep access to both tools because they are forerunners in their respective areas.
