Omniscient AI vs Trusul

Omniscient AI provides source-linked fact-checking through an API, a WordPress plugin, and a Chrome extension. An API response contains a consensus Trust Score, model verdicts, and source citations in structured JSON. Each request runs GPT-4o Mini, Perplexity Sonar Pro, and Gemini 2.5 Flash; the developer page says a consensus result returns in under three seconds. The WordPress plugin can add a Fact-vs-Opinion bar and automatically analyze published articles using the publisher’s API key. In Chrome, users can check a webpage or selected text and view results with supporting sources. Documentation also describes webhook delivery and an OBS browser source. Enterprise API v1 accepts claims up to 8,000 characters and lists ten supported languages. The pricing FAQ presents Trust Scores as a triage aid and recommends human review for high-stakes decisions. The try page offers five free checks after Google sign-in. The free plan has a $0 monthly base, then charges $0.005 per fact-check request; paid monthly plans include Always-On Pro at $399 and Agency at $1,000.

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.
