NewsGuard AI Launches in Germany, Austria, and More European Countries
NewsGuard has launched its AI service, NewsGuard AI, in Germany, Austria, France, Italy, the UK, and other European countries. The AI tool answers questions on current news topics using only approximately 12,000 news sources that NewsGuard has vetted for credibility and transparency. When journalistic content is used in responses, NewsGuard AI cites and links to the original articles, and the media outlets receive compensation. The service is subscription-based, with a free tier of ten queries per day and a premium subscription at eight euros per month after a two-week free trial. NewsGuard has no plans to introduce advertising. Publishers can participate as co-marketing partners, offering the service to their readers at a discounted rate and receiving 50% of the subscription revenue generated through their channels. This creates a potential indirect advertising effect, as frequently cited sources might leverage the credibility label for brand safety.
