FAXTR vs Omniscient AI

FAXTR is a fact-checking platform for reviewing claims, headlines, articles, article URLs, and LLM-generated text. It aggregates verdicts from more than 100 fact-checking organizations across more than 50 countries, rather than making its own final judgment on whether a claim is true or false. Visitors can make three checks without signing up; signing up provides more checks and history. FAXTR says it gathers data from the Google Fact Check Tools API and Google News RSS three times daily. For integrations, it offers a REST API with JSON responses at https://api.faxtr.com/v1. Verification endpoints are in private beta and require access; the API also includes a /v1/guard endpoint for scanning LLM responses for misinformation. FAXTR Verified records source and receipt details, source-text and debunk matches, and a published SHA-256 fingerprint of an article body. Publishers add it with one server-rendered link per article, without JavaScript or a runtime dependency on FAXTR. The Free plan is free, billed monthly; Starter is $49 a month.

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.
