Omniscient AI
What it is
Omniscient AI provides source-linked fact-checking for publishers through an API, a WordPress plugin, and a Chrome extension. An API response includes 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. The Chrome extension checks a webpage or selected text and presents 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, including English, Hindi, Spanish, French, German, Portuguese, Arabic, Chinese, Japanese, and Korean. Submitted claims are not used for model training. Requests run on Omniscient's infrastructure, which contacts upstream models over encrypted connections. API calls require Bearer-token authentication; dashboard users can revoke keys. The try page offers five checks after Google sign-in. API pricing starts with a $0 monthly base, then $0.005 per fact-check request; Trust Scores are described as a triage aid, not a substitute for human review in high-stakes decisions.
For and against
For
- Responses include verdicts, a Trust Score, and source citations.
- Three AI models run on each API request.
- Chrome extension checks pages or selected text.
- Five free checks follow Google sign-in.
Against
- Metered API usage costs $0.005 per request after the base.

- High-stakes decisions call for human review.
The verdict
Omniscient AI offers several routes to source-linked claim checks, from browser use to publisher integrations. Its own guidance positions Trust Scores as triage, so high-stakes conclusions still need human review.
Who it suits
Omniscient AI suits publishers looking to check claims in articles, web pages, or selected text and surface supporting sources. Its API and WordPress options are aimed at teams integrating checks into publishing workflows.
