Grokipedia
Grokipedia is a free online encyclopedia published by xAI, where every article is written and fact-checked by the Grok model rather than by human contributors. Roughly 5.85 million English entries, each carrying numbered external references.
What is Grokipedia?
Grokipedia is a general-purpose online encyclopedia published by xAI, the company behind the Grok model and, since SpaceX acquired it on 2 February 2026, trading under the SpaceXAI brand. Its defining trait is that no human writes it: articles are generated by Grok, and each one carries a dated banner reading Fact-checked by Grok — on the entry examined here, the check was four months old.
Scale is the headline figure. The public sitemap, dated 26 January 2026, lists 235 files of 25,000 URLs each, putting the catalogue at roughly 5.85 million articles. Coverage is deliberately indiscriminate: alongside science and biography sit record albums, television series and colloquial phrases. Every entry lives at grokipedia.com/page/{topic}.
An article reads far closer to a reference work than to a chatbot reply. The entry on artificial intelligence opens with an anchored table of contents and an infobox of key facts — acronym, parent discipline, who coined the term and when, founding event, key pioneers — then runs through sectioned prose carrying 433 numbered references to external sources and 189 internal links to other Grokipedia entries. Illustrations are credited back to the sites they came from. Readers can copy a deep link to any section, open a per-article edit history, or press a button to have the whole piece read aloud, picking among several voices and adjusting the speed. Search runs from the main bar or a Cmd+K shortcut, with suggestions appearing as you type.
Reading costs nothing and needs no account. Contributing does: signing in through an xAI account unlocks two forms, one to suggest a topic for a new article and one to propose a correction — the site asks you to select the offending passage and attach a source. Nothing is published directly; as the interface puts it, Grok will review your suggestion and add the article if it sees fit.
The product is web-only and English-only, and exposes no documented public API. Its content sits under the xAI Community License Agreement, with some articles additionally offered under CC BY-SA 4.0.

When to use Grokipedia / When not to
A quick filter to help you decide if Grokipedia is the right fit.
When to use Grokipedia
- Students and researchers who need a fast, free starting point on an unfamiliar topic, with a numbered bibliography to follow
- Journalists and fact-checkers hunting for background context and a list of external sources they can verify independently
- Teachers, tutors and curriculum designers assembling reference material across a very wide range of subjects
- Writers, copywriters and authors researching a subject before they start drafting
- Readers who would rather have a structured, sourced article than an unsourced chatbot answer
When not to use Grokipedia
- Anyone who must cite a peer-reviewed or human-validated authority: every article is machine-written and machine-checked
- Non-English speakers: there is no language selector, no hreflang alternates and no localised edition
- Developers wanting programmatic access: no public API is documented, and the internal /api/ endpoints are disallowed in robots.txt
- Mobile-first users expecting a dedicated app: Grokipedia is web-only, and the app-store listings on the publisher's domain belong to the Grok chatbot
- Contributors who expect to edit directly as on a traditional wiki: you can only suggest, and Grok decides what is applied

Pricing & Plans
Grokipedia is free of charge in its entirety. There is no paid tier, no metered quota and no paywall, and the site publishes no pricing page. Signing in with an xAI account — required only to suggest an article or an edit — is also free. Note that the pricing published on the publisher's domain applies to Grok and the xAI API, not to Grokipedia.
Data, GDPR & hosting
A consolidated view of how Grokipedia handles your data.
GDPR overview
GDPR implementation is concrete and documented, although the site never claims to be "compliant" in those words. xAI publishes a Europe Privacy Policy Addendum, effective 24 April 2025, covering the EEA, the United Kingdom and Switzerland. It names X.AI LLC as controller, gives a legal basis for each processing purpose — contract, legitimate interest or legal obligation — and lists data-subject rights: access, rectification, erasure, objection, restriction, portability, withdrawal of consent and complaint to a supervisory authority, plus a specific right to object to model training. Requests go through x.ai/privacy-portal, and a Data Protection Officer is reachable at privacy@x.ai. Local representatives are named for the UK, the EU and Switzerland. Transfers rely on the EU-US Data Privacy Framework and its UK and Swiss extensions, or on standard contractual clauses. A DPA and a 24-entry subprocessor list are published.
Who owns the data?
xAI's terms say that you own the content you submit, then carve Grokipedia out of that rule: Output is defined as what the Service returns "excluding output from Grokipedia". Article text is therefore not user property. It is designated as Material under the xAI Community License Agreement, with certain content additionally covered by CC BY-SA 4.0. On Grokipedia your own contribution is limited to article suggestions and proposed edits. Where a submission includes a person's image, likeness or voice, X.AI LLC receives the same rights over those attributes as over the rest of the content. The controller of personal data is X.AI LLC, a Nevada company based in the United States.
Reuse rights
Grokipedia content is not in the public domain. It is designated as Material under the xAI Community License Agreement, and the terms state that certain articles are additionally offered under CC BY-SA 4.0, which permits reuse and adaptation — including commercially — provided the source is attributed and derivative works carry the same licence. Because the terms say only that "certain" content is CC BY-SA 4.0, without marking which entries, a reuser cannot assume any given article qualifies and should treat the xAI Community License as the default. Separately, personal data supplied to the service is used by xAI to operate, support and improve the product and to train its models, on a legitimate-interest basis in Europe. That training use can be switched off through the data controls in the xAI account settings, and Private Chat content is excluded from training altogether. xAI states that it does not sell user data or share it for marketing or advertising purposes.
Data retention & training
Hosting summary
xAI states that it processes all personal information in the United States, where it says its primary data centres are located. No European or regional data-residency option is offered. The publisher maintains a public subprocessor list of 24 entries; every one is located in the US except an unnamed "xAI Subsidiary" in the United Kingdom. Cloud infrastructure is attributed to AWS, Google Cloud and Oracle, content delivery to Cloudflare and Hive, and web hosting and deployment to Vercel. The grokipedia.com domain itself resolves to a Cloudflare anycast address (104.18.19.2), so the responding edge node reflects the visitor's location rather than the storage jurisdiction. For European users, transfers out of the EEA, the UK and Switzerland rely on participation in the EU-US Data Privacy Framework and its UK and Swiss extensions, or otherwise on standard contractual clauses approved by the European Commission, the UK and Switzerland. No hosting jurisdiction specific to Grokipedia is published: these statements cover the xAI service as a whole.
Things to keep in mind
Risks and trade-offs to weigh before adopting Grokipedia.
- Treating machine-written text as settled fact: nothing here has passed human peer review, and the fact-check is done by the same model that wrote the article
- Citation laundering — quoting Grokipedia in schoolwork, journalism or legal filings as though it were an authoritative source
- Cognitive off-loading: the fluency and sheer length of the articles invite skim-reading instead of following the references down to the original source
- Single-source dependence: a general encyclopedia produced by one company's model carries that model's framing, and there is no competing editorial voice inside the site
- Third-party privacy: articles about people can restate personal information gathered from public sources, and the published correction procedure carries no obligation of result
- Age-appropriateness: the minimum age is 13, yet the publisher warns its models can produce content unsuitable for all ages
- Data flows you did not intend: contributing requires an xAI account, and account content feeds model training by default unless you opt out
Setup & Integrations
Technical difficulty
None. Grokipedia opens in any browser and needs no installation, no configuration and no API key. Reading is fully anonymous: there is no sign-up wall, no quota and no gate to clear before reaching an article. An xAI account is required only to suggest a new article or propose an edit, and creating one is free. In practice the only skill needed is knowing what to search for — and the discipline to follow the numbered references down to their original sources.

Should you pick Grokipedia?
Grokipedia is the most complete expression so far of a simple proposition: that a large language model can write an encyclopedia end to end. On volume it succeeds outright — roughly 5.85 million entries, free to read, no account, no quota, no advertising — and the articles are not thin. The sample entry examined here ran to dozens of sections with 433 numbered references, an infobox, internal cross-links and audio narration. As a first stop for orientation on an unfamiliar subject, followed by a walk down the reference list, it does real work.
The reservation is structural rather than incidental. The same model writes the article and then certifies it, so the fact-check adds no independent signal. There is no human peer review, no visible editorial board and no competing voice inside the site. xAI's own documents are candid about the consequence: the privacy policy concedes it cannot guarantee the factual accuracy of model output, and the terms of service pointedly carve Grokipedia output out of the content users own. Read it as a well-sourced index, not as an authority to cite.
Two practical limits narrow the audience further: everything is in English, and there is no public API or mobile app. The governance paperwork behind it is unusually thorough for a free product — a published DPA, a 24-entry subprocessor list, a full Europe privacy addendum, a named DPO and EU, UK and Swiss representatives — but all of it lives on the publisher's domain, and no postal address for X.AI LLC is published anywhere. Data is processed entirely in the United States, with no regional residency option.
Verdict: a genuinely useful, genuinely free research starting point, provided you treat every claim as a pointer to its source rather than as a finding.
