Factward vs Omniscient AI

Factward checks text, URLs, and PDFs by identifying factual claims and comparing them with web sources. Its AI model filters out opinions, predictions, and subjective statements, then retrieves up to five independent sources for each claim. Reports classify claims as Supported, Conflicting Sources, Refuted, or Insufficient Evidence, and include confidence, reasoning, linked sources, and a Trust Score. The service tracks when claims may have become stale and prompts users to check them again. A bookmarklet can send article text for review, and the Pro API can be used in a CMS or publishing pipeline. A beta Chrome extension highlights claims alongside verdicts and evidence, including when checking selected text from its context menu. Factward says submissions are used to produce results and are not sold or shared with third parties, though jobs and reports are stored in its database. Niche, paywalled, or very recent claims may lack evidence, and nuanced claims can be misinterpreted. The free plan allows two verifications per day; Pro costs $9 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.
