CitePulse · Institution
citepulse.theaslangroupllc.com
Institution research-output benchmark for grant offices, research-strategy agents, and comparison shopping — works count, total citations, h-index/i10-index, a 10-year output/citation trend, and topic-strength breakdown (OpenAlex). Optionally benchmark two institutions side by side.
CitePulse · REF Check
citepulse.theaslangroupllc.com
Bibliography verification for AI research agents — POST up to 20 citations (DOIs or free-text references) and get a per-reference verdict: exists/not-found, retracted/withdrawn (Crossref + Retraction Watch + OpenAlex), and title/author/year mismatches against a real record. Built for agents auditing LLM-generated bibliographies before a citation ships.
CitePulse · Literature Brief
citepulse.theaslangroupllc.com
State-of-research synthesis for a specific question — grounded in top OpenAlex + Semantic Scholar results with full citations (DOIs). Built for AI research agents that need a citation-backed starting point fast; explicitly not a substitute for a full systematic review.
