What Is Perplexity AI and How Do You Use It? The Features Changing Search Engines
Originally published in Turkish. Read the original →
Instead of the link clutter of traditional search engines, Perplexity AI gives sourced, instant and direct answers to questions, redefining the AI-powered research experience.
For more than twenty years, the experience of searching for information on the internet followed similar patterns: typing a keyword, browsing through the ranked blue links, weeding out the ads and digging at length through the websites where the information you wanted was hidden. But the rise of generative AI has completely renewed our habits for accessing information. One of the most important pioneers of this transformation, Perplexity AI, abandoned the link-listing logic of traditional search engines and brought the concept of an "Answer Engine" into our lives.
Scanning the internet in real time for the questions users ask and synthesizing the information it gathers with transparent source citations, the platform has become an indispensable productivity tool for researchers, software developers and professionals.
What Is Perplexity AI and How Does It Work?
Founded in 2022, Perplexity AI is an AI-powered knowledge engine that brings advanced large language models and live web crawling technologies together in a hybrid structure. The platform's most fundamental difference is that it isn't limited to static training data and can access real-time internet data instantly.
Working in the background with a RAG (Retrieval-Augmented Generation) architecture, the system follows these steps: When the user asks a question in natural language, Perplexity splits it into multiple sub-queries. It scans hundreds of reliable sources on the web and filters out the most current and consistent information. It then presents this information to the user as a clear, fluent and structured answer.
The most critical point is that the system places numbered footnotes next to every sentence it presents. Users can verify with a single click which website, academic paper or official report a piece of information came from. This transparency minimizes the "hallucination" (making up information) problem frequently seen in traditional AI chatbots.
The Key Features That Make Perplexity AI Stand Out
Perplexity has advanced toolsets that boost research productivity, going far beyond being a simple question-and-answer box:
1. Focus Modes
When you want to limit your searches to specific pools of information, Focus modes come into play:2. Pro Search (Multi-Step Deep Research)
When you ask complex questions, Pro Search mode asks the user clarifying follow-up questions instead of closing the topic with a single query. After clarifying the scope of the need, it runs a multi-step research process and produces charts, comparison tables and in-depth analyses.3. Collections and Sharing
The platform lets users categorize the research they carry out. Custom system instructions can be assigned to collections created for a project or topic, related chats can be organized into folders, and they can be shared with colleagues through a single link.The Key Differences Between Perplexity AI and ChatGPT
- One of the things users are most curious about is how Perplexity and ChatGPT differ. Although both platforms are built on AI, they serve different purposes:
- Accuracy and Freshness of Information: Perplexity has a clear advantage in real-time web access and transparent source citations. It lets you check sources for current news, market data and technical research.
- Creativity and Conversational Depth: ChatGPT is more flexible for story writing, creative brainstorming, role-play and long-running conversational scenarios.
- Purpose of Use: While Perplexity works like a "research assistant and search engine", ChatGPT has more of a "general-purpose thinking partner" identity.
How to Use Perplexity More Effectively
- To get the most out of the platform, you need to set aside your traditional search engine reflexes:
- Ask Detailed and Specific Questions: Instead of general phrases like "history of AI", ask questions with clear context, such as "What are the main obstacles to the commercial adoption of open source AI models between 2024 and 2026?"
- Deepen the Topic with Follow-Up Questions: After getting an answer, instead of ending the topic, build a chain of analysis with follow-up questions like "What is the cost impact of this on SMEs?"
- Check the Sources: Get into the habit of verifying the original data by looking at the footnote links provided.
In addition to the core features offered in the free tier, Perplexity AI's Pro subscription lets you switch freely between the most powerful models such as Claude 3.5 Sonnet and GPT-4o and offers unlimited file analysis. In this new era, where blue links give way to directly synthesized information, Perplexity represents the future of how we search the internet.
