A knowledge platform built for people and structured for AI.
worldwiki.io publishes verified entity pages, sourced answers and comparisons that humans can trust and AI search engines can cite. It is operated by twolegend in Seoul, Korea.
Mission
AI assistants now answer a growing share of the questions people used to type into a search box. The answers are only as good as the pages they can find and trust. worldwiki exists to give those systems, and the people who use them, a reliable, sourced, entity-centred description of the world.
We are not a directory and not an advertising network. Every page starts from a real entity, every claim points to a source, and paid placements are always labelled.
Methodology
Entity first
A page is created only for a real, identifiable entity: a person, organization, product, technology, place or concept. It carries a stable identifier, aliases, relations and external identifiers (Wikidata, official URL) so that humans and machines resolve the same thing.
Source first
Facts and answers cite primary sources ranked by reliability: government, academic, official primary, reputable journalism, industry, organization. Provider statements are recorded as official claims, not as verified facts, until an independent source confirms them.
Structured for AI
Every page is server-rendered with a JSON-LD @graph (WebPage, entity node, BreadcrumbList, QAPage), canonical URLs, sitemaps with real modification dates, llms.txt and a public read API. Crawler access is documented and monitored.
Verified and dated
Verified pages have had their identity, official URL and key claims checked by an editor against primary sources. Every page shows Published, Updated and Last verified dates and keeps a revision history.
Editorial independence
Advertisers and paid customers cannot buy facts, sources, rankings or verification. What they can buy is clearly labelled placement and measurement services. Medical, legal and financial content is published only after expert review. Read the editorial policy and source policy for details.
Company
worldwiki.io is developed and operated by twolegend. Company details, registration numbers and contact information are shown in the footer of every page and on the terms of service.
