Eustace vs Scrutinly

Eustace is a web-based fact-checking workspace for writers and researchers working with AI-assisted drafts. Users can paste text or import a URL, PDF, or Word file; scanned PDFs are processed with OCR. The service extracts candidate factual claims and displays their original quotes so users can select which to verify. Approved claims are checked against fresh web sources rather than the submitted document. Its ledger uses ten verdicts and three confidence levels, and the product says it signals uncertainty when evidence is thin or mixed. Users can inspect sources, attach private evidence, override a verdict with the change recorded, and export a Markdown report with claims, verdicts, confidence, and citations. Eustace says it does not sell user data or use documents to train AI models. The Free plan provides 25 lifetime verifications; Pro costs $19/month for 500 each month, with optional $0.05-per-claim overage turned off by default. Automated verdicts, confidence labels, and summaries can be wrong, incomplete, or out of date, so they are intended to support rather than replace editorial judgment.

Scrutinly is a web-based fact-checking service for articles, claims, URLs, social posts, and images. It extracts checkable statements from supplied text and evaluates each against current web sources. URL checking fetches the article directly, avoiding manual copying. Results classify claims as Supported, Unsupported, Mixed, or Satirical and provide links to the sources used. A stacked bar summarizes the proportions of Supported, Unsupported, and Mixed claims in a check. Image analysis is in beta: it estimates signs of AI generation or changed context, then gives a probability score and explanation; the service warns that these evaluations may be unreliable. Results remain in search history, and identical content can reuse cached output without consuming tokens. Security features listed by the site include two-factor authentication, PBKDF2 password hashing, and JWT sessions; searches are private to each account and not sold or shared. The Free plan costs nothing and includes 150,000 tokens. Pro costs $12 a month, while Max costs $49 a month.
