OpenAI has made its ChatGPT Search engine more accessible by removing the need for users to register, allowing anyone to use the AI-powered search tool. This move positions ChatGPT Search in direct competition with traditional search engines like Google and Bing, which require users to navigate through links, while ChatGPT provides synthesized answers with source citations. The change follows a trend seen in other AI search tools like Perplexity, which also operates without requiring user accounts. This development is part of a broader shift towards 'answer engines' that aim to deliver quick and efficient search results, potentially reshaping online search behavior.
