scite.ai vs Sourcely

Scite helps research teams ask literature questions and get answers tied to full-text papers, not abstract snippets alone. Its Assistant searches across 280M+ full-text scholarly articles, and Smart Citations show whether later work supported, contradicted, or mentioned a finding.

General research chatbots guess when paywalls block the PDF. Scite licenses content from Wiley, SAGE, and 40+ other publishers, so it reads inside the paper and links each claim to a specific sentence you can verify in one click. That evidence-first design targets literature reviews where you need to know if a result still holds, not just that it exists.

Grad students run disputed-or-affirmed checks before citing a paper. R&D teams trace grants, clinical trials, and patents in one search. Pro users get API access, 2,500 MCP credits per month, and collections up to 10,000 papers. Scite also plugs into Claude, ChatGPT, and Zotero so answers show up inside existing workflows.

Sourcely helps students and researchers find academic sources by pasting an essay, paragraph, or paper draft. It searches a catalog of 200 million plus papers, highlights citation-worthy sentences, and returns summaries with exportable references in hundreds of citation styles. The workflow covers discovery, credibility checks, and bibliography building in one browser app.

Google Scholar returns keyword matches. Sourcely reads your draft context to surface papers that fit specific claims, then lets you chat with sources, run deep searches, and download PDFs when available. Paid tiers add monthly deep-search and credibility-check quotas that free keyword search tools do not bundle.

Undergraduates, graduate students, and researchers use it to speed literature reviews and citation work. The site reports 250,000 plus users, with Ultra at $11 per month and Max at $23 per month on annual billing during the listed summer sale.
