Your data. Better questions.
No unsupported diagnosis.

Paste your research evidence or choose a document. A transparent local audit identifies provenance gaps, contradictions, unanswered questions and the boundaries of justified inference — before any clinical claim.

Start an evidence check

Drop a redacted research document or type observations. TXT, CSV, TSV, JSON, Markdown, HTML, DOCX and XLSX are parsed locally (browser capabilities permitting). Text-based PDF import may load a public PDF.js parser online; scans need manual transcription. Files stay in browser memory; do not enter personally identifying patient information.

Not a diagnostic or treatment service. Cancer is a medical condition requiring qualified evaluation. This tool does not diagnose, grade, stage, prognosticate or recommend therapy. PIGA Gate 2 for patient-specific clinical action remains BLOCK even when the evidence-check status is ALLOW for research documentation.

Verified Blocked Risk (VBR) · Optional evidence of a prevented action

A BLOCK message alone is not VBR. A verified blocked risk additionally requires evidence that the prohibited action created no external effect. References entered here are not independently authenticated by the app.

03 · Verified Blocked Risk · Strict non-execution evidence

A blocked path is not yet proven harmless.

A PIGA rejection is a decision, not an independently verified non-action. To establish a real VBR, a separate readback of the target system or an auditable action trace must prove no external effect occurred. This static page cannot perform such a readback.

VBR NOT VERIFIED

Add the attempted risk path, blocked admission, and independent non-effect trace to create an auditable candidate. It will remain unverified until external evidence is checked.

EU AI Act: What matters?

A legal checklist, not automatic compliance. Applicability depends on intended purpose, AI functionality, product classification and role. A non-AI spreadsheet is not automatically an AI system.

Articles 6–15 · classification, risk, data, logs, transparency, oversight, accuracy ↗ 2026 amendment · high-risk dates: Annex III 2027 / Annex I products 2028 ↗ FDA CDS guidance · intended use and independent review ↗

Conditional AI Act articles: 4 (literacy), 6 (classification), 9 (risk), 10 (data governance), 11 (documentation), 12 (record keeping), 13 (instructions/transparency), 14 (human oversight), 15 (accuracy/robustness/security), 16 (provider obligations), 26 (deployer), 27 (fundamental-rights impact in specified cases), 43 (conformity), 49 (registration), 50 (transparency where applicable), 72 (post-market monitoring). These are not all mandatory for every system.
