Overview
AI research tools cover different jobs. Some search the open web, some organize scientific papers, and others help synthesize material and draft an explanation. This guide compares documented workflows in a verified subset of six products; it does not rank answer quality or claim exhaustive testing.
## ChatGPT
ChatGPT combines conversational assistance with writing, learning and web research. Its official overview also describes voice conversations and creative tools. For research, use it to explore a question and draft material, then check important statements against original sources. [Official information](https://chatgpt.com/overview/).
## Claude
Claude supports drafting, information synthesis and data analysis. Its official overview describes editable deliverables and connected work tools. It is useful to separate the material you provide from information retrieved through a connector, whose availability depends on access. [Official information](https://claude.com/product/overview).
## Elicit
Elicit focuses on scientific research workflows. Its official site describes academic literature search, uploaded documents and cited reports or tables. A cited output helps locate supporting material; it does not replace checking a study’s methods, population and conclusions. [Official information](https://elicit.com/).
## Consensus
Consensus searches scientific literature and synthesizes findings with citations. Its official documentation explains that claims can be traced to the research used. Compare the underlying papers when findings differ, rather than treating a summary as a universal scientific conclusion. [Official information](https://help.consensus.app/en/articles/9922673-how-consensus-works).
## Perplexity
Perplexity combines conversational answers with web search and source links. Its official help documentation describes synthesizing information from multiple sources. It fits web-based exploration, while plan-specific research or file features should be checked separately. [Official information](https://www.perplexity.ai/help-center/en/articles/10352155-what-is-perplexity).
## SciSpace
SciSpace provides paper search, literature-review tools and questions about PDFs. Its official site also lists writing assistance and citation generation. These functions address different parts of research preparation; verify the bibliography and read relevant original passages before relying on an answer. [Official information](https://scispace.com/).
Start with the source type you need: scientific papers, web pages or documents you already have. Test one representative question, open the cited sources and confirm the passages support the answer. Check current product access and limits before adopting a workflow.
