SearchGPT
OpenAI's search-engine prototype, originally launched as a standalone product — now largely folded into ChatGPT Search. Delivers AI-generated answers with source citations.
SearchGPT — explained in more detail
SearchGPT was OpenAI’s publicly announced attempt (July 2024) at a standalone search experience — answers generated by the GPT model, combined with real-time web search results and explicit source links. The prototype was folded into ChatGPT Search from late 2024 onward; SearchGPT no longer exists as a standalone product.
For SEO/GEO this means: optimizing for ChatGPT Search is equivalent to optimizing for SearchGPT. Key levers are crawl permissions for OAI-SearchBot and GPTBot, clearly structured content with citable statements, and Schema.org markup for authors and sources.
Example / In practice
Anyone wanting to be cited in ChatGPT Search answers should check: does robots.txt allow OAI-SearchBot? Does the site deliver clear, fact-based statements with source attribution? Are author pages marked up as Schema.org Person? These three points significantly increase the chance of being cited.
Distinction from similar terms
ChatGPT Search is the productized form of SearchGPT — today’s relevant term. AI Overviews are Google’s counterpart. Perplexity is a standalone AI search engine with a different focus (source depth rather than conversation).
