What is Google?
Google is a search engine. It has the world’s largest user base and is considered No. 1 in the global marketplace.
The purpose is to fetch relevant information for those who search.
Google search engine works on 3 levels:
Crawlers
Google crawlers, also known as bots, crawl links on the internet and reach web pages or websites.
Index
The crawled information is stored in Google’s huge repository called the index.
Algorithm
Google’s algorithm fetches the relevant information for the user from the index.
- A user types a keyword.
- The algorithm checks the information in its index, matches the keyword with crawled information, and displays it in the search results.
- The user gets the information in the form of links (web pages) on Google’s search result pages.
What is ChatGPT?
OpenAI’s ChatGPT is a large language model-based AI assistant.
In simple words, it is a smart chatbot that has some knowledge because it is trained on massive sets of text data.
The purpose is to generate text and provide quick responses.
It is known for its generative capabilities (Generative AI) – not primarily as a knowledge base, because its knowledge depends on its training data and connected tools.
It gets refined in cycles.
This is a slight shift from searching for information to asking questions.
Type a prompt and get an instant response.
It can process in-depth queries, comprehend complex questions, and generate responses instantly.
What is Perplexity?
Perplexity AI is an AI-powered search engine, also known as a new-age answer engine.
It is like a combination of LLM + search engine capabilities.
The purpose is to synthesize information using advanced search and generate direct answers with the help of LLMs, while also providing citations as references to support the information.
It mainly works on a retrieval mechanism by connecting to external real-time data sources on the web, rather than only relying on indexed web pages like a traditional search engine or generating responses solely from training knowledge.
Ask a question and get a response along with citations that you can explore, verify, and conclude from.
Conclusion
Google vs ChatGPT vs Perplexity
Google – gives information in the form of links.
ChatGPT – gives answers instantly using trained knowledge and connected tools.
Perplexity – gives answers along with citations that show where the information is sourced from.
