Drop a PDF, Word, or text file. Mephistopheles pulls out every factual claim, checks each against independent sources, and flags what's wrong or unverifiable — so you catch errors before they cost you. Sensitive documents are de-identified first, on our own infrastructure — names, dates, and IDs are stripped before anything is checked, and nothing is sent to a third‑party AI in raw form.
Mephistopheles raises the floor on factual errors — it flags likely mistakes for you to review. It doesn't certify a document as true, and "unverifiable" means it couldn't find a source, not that the claim is false. Always use your own judgment.
