# sourceverify.ai

> SourceVerify verifies academic and professional references against real sources. It detects hallucinated citations, confirms DOIs, and returns an auditable verdict with the evidence behind it.

SourceVerify extracts references from text or PDFs and verifies each one against scholarly databases and the open web — OpenAlex, Google Books, Google Search and Google Scholar — plus publisher pages, PubMed records, and any URL a reference points to. Every reference receives one of four verdicts (VERIFIED, VERIFIED WITH ERRORS, NEEDS HUMAN REVIEW, UNVERIFIED) under SVRIS, an open and deterministic standard, with the supporting evidence attached so the result can be audited rather than trusted on faith.

Verification runs in the web app, through a REST API, or from AI assistants via an MCP server, a CLI, and a Claude Skill. New accounts receive 25 complimentary tokens with no card required.
