What Omniscient AI is
Omniscient AI provides source-linked fact-checking through an API, a WordPress plugin, and a Chrome extension. An API response includes a consensus Trust Score, individual 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 check returns in under three seconds. The WordPress plugin can add a Fact-vs-Opinion bar to published articles and automatically analyze them using the publisher’s API key. The Chrome extension checks a webpage or selected text and displays 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 supports English, Hindi, Spanish, French, German, Portuguese, Arabic, Chinese, Japanese, and Korean. Submitted claims are not used to train models. Requests are processed on Omniscient’s infrastructure, which contacts upstream AI models over encrypted connections. API calls require Bearer-token authentication, and keys can be revoked in the dashboard. The try page offers five checks after Google sign-in, and Trust Scores are described as a triage aid, with human review recommended for high-stakes decisions.
