Set up two-step sign-in
AiSJ Cloud asks for a code from your phone each time you sign in. It takes about two minutes, once.

- In the app, add an account and scan this picture:

Welcome
Paste a reference list, or upload a Word, PDF or text file. AiSJ checks each reference against CrossRef, PubMed, Europe PMC, OpenAlex, ClinicalTrials.gov and Open Library, and tells you whether the paper is real and whether the DOI or PMID printed with it belongs to that paper.
Only the citation text is sent to the public databases, and one citation plus one database record to the AI when a match is doubtful. Your reference lists are not saved: the service keeps counts only, and results disappear from memory two hours after a check finishes. Please do not paste patient information.
