SciSpace is an AI research assistant for students and researchers, made by PubGenius Inc. in California. Its literature search covers more than 280 million papers, and its other tools work on PDFs that users upload. It is not a web search engine, and it documents no crawler that a site owner can allow or block.

What SciSpace does

The SciSpace llms.txt file lists its main tools:

Tool What it works on
Literature Review search An AI search over more than 280 million papers, with summaries of the results
Chat with PDF A PDF that the user uploads. Answers link to paragraphs and sections of that PDF
Extract Data from PDFs Several uploaded PDFs. It pulls findings and tables from them
AI Writer, Paraphraser, Citation Generator Text and references that the user gives it

SciSpace also has a Chrome extension to read and chat with PDFs in the browser, and mobile apps. The site footer names PubGenius Inc. in Milpitas, California, as the company.

Where the papers come from

SciSpace describes where its research content comes from on its Data Sources page. SciSpace also publishes public pages for papers, authors, journals, conferences, institutions and topics on scispace.com. It lists these pages in the sitemaps that its robots.txt file names.

What a site owner can control

  • SciSpace documents no crawler name, user agent or robots.txt token. There is no documented way to allow or block it.
  • SciSpace documents no form to add a website or to remove one from its search.
  • The PDF tools work on files that users upload. A user can upload a PDF from any source, including your site.

For questions about content on SciSpace, the site footer gives the address [email protected].

For other AI tools that search research papers, see Semantic Scholar, scite and Elicit.
