Free AI-generated encyclopedia from xAI, launched October 2025 with 885,279 articles and grown past six million.
Grokipedia is xAI's encyclopedia, generated and maintained by its models rather than by volunteer editors, and pitched by Elon Musk as an alternative to Wikipedia. It went live on 27 October 2025 with 885,279 articles, many adapted from existing sources including Wikipedia itself, and reporting put it past 1.8 million by late 2025 and above six million by January 2026. Reading is free and no account is required. Because the corpus is machine-written and continuously rewritten, merged and pruned, xAI publishes no stable article count and articles can change under you between visits.
Free to read with no account required; xAI has announced no paid tier.
Use tool ↗The scale is real — millions of articles inside a year, which no human-edited encyclopedia could approach — and it is free to read. The cost of that scale is provenance: entries are machine-written, are rewritten without notice, and carry none of the talk-page argument and citation discipline that makes a wiki auditable.
Watch out: Entries can be silently rewritten between visits, so anything quoted from here should be captured with a date and verified against a primary source.
