Signal review
A free web tool for checking claims, headlines, and URLs with scored verification.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Signal is a web-based AI news verification platform for people and teams assessing the credibility of current news and online claims. Users can enter a claim, headline, or URL and receive a Signal Score across six verification dimensions, along with supporting source trails. Its focus is current-news assessment rather than broad content analysis, making it a fit for readers, researchers, editors, and teams that need a structured way to review breaking information.
The free tier costs 0 and includes AI Copilot chats and audio briefings alongside the core verification features. Signal can cross-verify claims against multiple independent sources, provide context through the AI Copilot, and deliver personalized breaking-news alerts. Public correction and retraction tracking adds an ongoing layer to the review process, helping users follow how a claim’s status changes after publication. Audio briefings extend the product beyond text-based checking, while the six-dimensional score gives the verification result a consistent structure.
Signal also accepts Twitter/X and Reddit ingestion, which helps bring social posts into a news-verification workflow. Its listed source type is web, and its supported content is limited to claims, headlines, and URLs. That focused scope should suit buyers who want free claim and breaking-news verification in a browser, especially when independent-source comparison and correction tracking matter. Buyers seeking broader input coverage, API access, or browser-wide fact-checking should consider a product with a wider platform and integration range instead.
