AI search tools can supplement your other literature searches, for example at the beginning or the end of your search process. The tools are constantly evolving and often include both free and paid features. The AI tools search through content from open, scientific archives.

Open archives
Open, scientific archives contain titles, abstracts, and sometimes the full text of a large number of articles, working papers, etc. The content in the open archives is not selected in the same way as in established scientific databases, so reflect critically on your search results. You can search the open archives either via an AI search tool or directly in the archive.
