Citation Verification
Verify that citations in a document actually resolve and support the claims they're attached to. Uses the Stipple API (free anonymous tier, no signup) for citation resolution, arithmetic recomputation, and unsupported-claim detection.
When to use
- Before submitting or publishing a research report, tender response, or whitepaper
- Reviewing an LLM-generated document (LLM citations are plausibly-formatted and frequently wrong)
- Due diligence on third-party reports
- Academic reference checking
Instructions
- Get the document. Ask the user for a URL to the report, or a local file path (PDF, DOCX, Markdown). If the user pastes text directly, skip to step 3 with
textinput.
- Run verification. POST the document to Stipple's citation verification endpoint:
``bash curl -X POST https://www.stipple.sh/v1/verify-references \ -F "file=@report.pdf" \ -H "Authorization: Bearer $STIPPLE_API_KEY" ``
The anonymous free tier works without the Authorization header. Deep mode (?deep=true) costs more credits but cross-checks citations against live web sources.
- Interpret the response. The result includes:
verification_coverage— percentage of claims verified (e.g. "78%")citations[]— per-citation status: resolved and matching, resolved but mismatched, or unresolvable, with the issue explained

check-identity-pack
Run an AFP 100-point or AUSTRAC safe-harbour identity check over a set of documents, and report exactly what's missing. Use when the user asks to check identity documents, verify someone's ID for onboarding, or assess whether a document pack satisfies Australian identity requirements.
detect-ai-text
Estimate whether a document's prose was written by AI, with the linguistic tells and honest abstention on non-prose. Use when the user asks whether an essay, report, CV, submission, or article was AI-generated — for triage, not proof.
extract-document-data
Extract structured, grounded fields from documents — values cite their page, missing values abstain instead of hallucinating. Use for parsing invoices, payslips, statements, contracts.
find-matching-tenders
Find open AU/NZ government tenders matching what a company does, ranked by fit with why and gap analysis. Use when the user asks to find tenders, bid opportunities, government contracts, or RFPs for their business (or a client's).
screen-adverse-media
Screen a person or organisation for adverse media coverage, PEP status, and sanctions exposure — corroboration-gated, returns "review" never "guilty". Use when the user asks to screen someone before onboarding, partnership, or investment; for AML/CTF flows; or for ongoing counterparty monitoring.
verify-document
Check whether a document (PDF or image) shows signs of tampering or forgery before you rely on it. Use when the user asks to verify a payslip, invoice, bank statement, ID document, contract, or any document where authenticity matters.
