Eustace vs Trusul

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 Automated verdicts, confidence labels, and summaries can be wrong, incomplete, or out of date, so they are intended to support rather than replace editorial judgment.

Trusul is a web tool for analyzing claims, comparing news coverage, asking about current events and reviewing cited evidence. Its analyzer examines credibility signals in claims, articles, messages and public URLs, including sensational wording, emotional pressure, clickbait, all-caps patterns and forceful punctuation. Reports combine a credibility score, risk verdict, explanation, evidence breakdown, warnings, missing information, limitations and cited sources. The site describes its 0–100 score as a composite drawn from three independent signals.

Compare Coverage places two reports or pieces of content side by side; differences are prompts to investigate, not proof on their own. Ask Trusul answers current-news questions in English using available citations and notes evidence and coverage limitations. For this feature, users can upload PNG, JPEG, WebP, PDF, DOCX or TXT files up to 5 MiB, processed temporarily for the request. Optional claim-verification queries may send short excerpts to Google Fact Check Tools API or NewsData.io. Plans include a free option, monthly subscriptions and one-time analysis credits, though some subscriptions and credit packs are listed as opening soon. Trusul describes itself as decision support, not a fact-checking authority.
