What it is

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.
