Many generative AI systems now have a feature called “Deep Research” — sometimes called “Deep Search” or “Deep Think.” They are designed to generate long reports or literature reviews instead of short answers.
Deep Research is available in free and paid versions of Gemini, ChatGPT, Grok, Kimi, Perplexity, and others. In Claude it’s only found in the paid version. These systems search only open websites, not scholarly content that lives behind paywalls.
Deep Research functionality is also available in systems that search scholarly data.
For example, Elicit offers a “research report” feature. Elicit searches scholarly data from Semantic Scholar instead of only the web. Undermind, SciScpace, and Ai2 Scholar QA offer a similar feature, also using data from Semantic Scholar.
These are not comprehensive search tools
Since many of these academic systems are based on Semantic Scholar, it’s important to know that the scope of Semantic Scholar is vast, but still smaller than Google Scholar and specialized library databases. So you won’t get a comprehensive search with one of these tools alone.
But they may help you surface research you didn’t find using traditional keyword searching of library databases, because they use semantic search.
