Elon Musk has unveiled a new venture called Grokipedia, an online encyclopedia driven by crowdsourcing, which he aims to establish as a formidable contender to the well-known Wikipedia.

In a recent social media announcement, Musk revealed that Grokipedia.com is “now live,” emphasizing its mission to deliver “the truth, the whole truth, and nothing but the truth.”

Previously, Musk has been vocal about his criticisms of Wikipedia, accusing it of being laden with “propaganda” and urging users to reconsider donating to the nonprofit organization that manages it. Back in September, he disclosed that his artificial intelligence firm, xAI, was in the process of developing Grokipedia.

The Grokipedia platform features a clean and straightforward design, offering little more than a search bar for users to enter their inquiries. At present, the site boasts 885,279 articles. In contrast, Wikipedia claims to house over 7 million articles in the English language alone.

Similar to Wikipedia, Grokipedia allows users to search for a wide array of topics, from popular figures like Taylor Swift to significant events such as the baseball World Series, or iconic landmarks like Buckingham Palace.

While Wikipedia is written and edited by volunteers, it’s unclear how exactly Grokipedia articles are put together. Reports suggest the site is powered by the same xAI model that underpins Musk’s Grok chatbot, but some articles are seemingly adapted from Wikipedia.

The San Francisco-based Wikimedia Foundation said in a statement Tuesday that it is “still in the process of understanding how Grokipedia works.”

As a huge trove of well-constructed sentences with little restriction on how it’s used, Wikipedia has been a key source used to train AI chatbots, including Grok’s rivals ChatGPT and Google’s Gemini.

“This human-created knowledge is what AI companies rely on to generate content; even Grokipedia needs Wikipedia to exist,” said the Wikimedia Foundation.

Wikipedia for months has been a target of the political right. Republican lawmakers in the U.S. Congress launched an investigation in August of alleged “manipulation efforts” in Wikipedia’s editing process that they said could inject bias and undermine neutral points of view on its platform and the AI systems that rely on it.

Wikipedia encourages its volunteer editors to cite nearly every sentence or paragraph with a primary source, and sentences not verified can be challenged and removed. Some of Grokipedia’s entries are thinly sourced, such as an entry on the Chola Dynasty of southern India that has three linked sources, compared to Wikipedia’s that has 113 linked sources plus dozens of referenced books.

Grokipedia’s entry on Wikipedia accuses the site of having “systemic ideological biases – particularly a left-leaning slant in coverage of political figures and topics.”

The Wikimedia Foundation said in its statement Tuesday: “Unlike newer projects, Wikipedia’s strengths are clear: it has transparent policies, rigorous volunteer oversight, and a strong culture of continuous improvement. Wikipedia is an encyclopedia, written to inform billions of readers without promoting a particular point of view.”
