Scholar Sidekick (Claude)

Scholar Sidekick Anthropic verified Resolve any scholarly identifier (DOI, PMID, PMCID, ISBN, arXiv, ISSN, ADS, WHO IRIS) into 10,000+ CSL styles or nine export formats, single or batch, plus retraction, open-access, and citation-verification checks (Topaz et al. Lancet 2026 fabrication-pattern detection).

The format/export/resolve tools accept a single identifier or a comma/newline-separated batch, so an assistant can chain resolveIdentifier → formatCitation → exportCitation in one prompt for an end-to-end 'raw IDs → exportable bibliography' workflow. Three single-citation checks complete the picture: checkRetraction surfaces retractions, corrections, and expressions of concern from Crossref / Retraction Watch; checkOpenAccess returns OA status and the best legal landing or PDF URL from Unpaywall; verifyCitation cross-checks the cited title against the resolved record at the cited identifier to detect the AI-driven fabrication pattern documented by Topaz et al. (Lancet 2026 — 1 in 277 biomedical papers in early 2026 contains at least one fabricated reference; the dominant pattern is real DOI + invented title, which simple identifier resolution cannot catch). Each formatted response carries a provenance metadata block (formatter, styleUsed, requestId, warnings) so users can see exactly which engine produced each citation.

Anthropic does not control which tools developers make available and cannot verify that they will work as intended or that they won’t change.
