In their own words
Eustace
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 Automated verdicts, confidence labels, and summaries can be wrong, incomplete, or out of date, so they are intended to support rather than replace editorial judgment.
FactPress
FactPress is a paid web tool for writers and publishers checking WordPress articles. It identifies claims and evaluates each fact separately across multiple AI models, marking a statement verified only when the models independently agree. Checks run inside the WordPress editor, so the listed workflow does not require copying article text into another service. The advertised plan allows up to 100 verifications every week. FactPress provides automatic fact-checking, claim detection and API access, with WordPress article content as the supported content type. Its pages offer Google sign-in and state that email is used only for account access. The product is presented for reviewing potentially inaccurate or risky statements before publication. The listed platform is web, and the provided pages do not state iOS or Android apps. FactPress therefore focuses on claim review within WordPress rather than describing a broader publishing environment or additional content formats.
