Grok
Grok is a multimodal AI assistant from X.AI LLC that combines conversation, live web and X search, image and video generation, voice and coding help in a single thread, available free on the web, iOS and Android.
What is Grok?
Grok is the conversational assistant built by X.AI LLC, a Nevada company that now trades under the SpaceXAI brand after SpaceX announced its acquisition of xAI on 2 February 2026. It runs in the browser at grok.com, as an iOS app, as an Android app and inside the X platform, and the flagship model quoted across the site is Grok 4.6. The publisher describes it as a truth-seeking assistant whose mission is to accelerate scientific discovery.
The product is organised around four modes. Chat handles everyday writing, research and recaps, showing reasoning you can follow step by step. Search queries the open web and live X posts, so answers reflect what is happening now rather than a training cut-off, and it returns citations to primary sources. Multi-agent sends several agents at a hard question in parallel, each showing auditable work before the results merge into one cited answer. Imagine turns text or a reference photo into images and video inside the same thread, up to 2K stills and fifteen-second clips, editable by follow-up prompt.
Around those modes sit code generation and debugging, file and PDF analysis, vision understanding for screenshots and diagrams, a writing canvas with inline suggestions, custom instructions, memory carried across conversations, shareable and revocable public links, and voice conversation with sub-second latency across twenty-seven voices and thirteen personalities. The publisher claims support for more than thirty languages without listing them. Since May 2026, connectors have plugged Grok into SharePoint, Outlook, OneDrive, Google Workspace, Notion, GitHub and Linear, and a bring-your-own Model Context Protocol server opens the same door to in-house tools.
The same models are exposed through a documented API at docs.x.ai, with Python and TypeScript SDKs and OpenAI SDK compatibility. xAI advertises 300 million queries handled daily, more than a million API calls a day, median latency under 200 milliseconds and a 150,000-GPU cluster. SOC 2 Type I and II is listed on every tier, including the free one.

When to use Grok / When not to
A quick filter to help you decide if Grok is the right fit.
When to use Grok
- Anyone who needs answers about breaking events, since Grok searches the web and X live and cites primary sources
- Writers, researchers and analysts handling drafting, summarising and document or PDF analysis every day
- Developers who want to write, debug and explain code without leaving the conversation
- Creative teams generating images and short videos from a prompt or a reference photo, then editing them by follow-up
- Teams whose documents already live in SharePoint, OneDrive, Google Workspace, Notion, GitHub or Linear, thanks to the connectors
When not to use Grok
- Under-13s, who are barred by the terms, and 13 to 17 year olds without a parent or guardian's agreement
- Organisations that need confidentiality by default, because the terms grant xAI an irrevocable, perpetual, sublicensable worldwide licence over inputs
- Buyers who require data residency outside the United States on a consumer plan, since all personal data is processed in the US
- Procurement teams that need a firm quote before signing, as the Lite, Team, Business and Enterprise tiers carry no published price
- Users who expect guaranteed factual accuracy, which the publisher explicitly declines to promise
How to use Grok
A typical end-to-end flow, from setup to results.
- Open grok.com in a browser, or install the iOS or Android app
- Sign in with an X account or an email address so history syncs across devices
- Start typing a question, or tap the microphone to talk to Grok
- Switch mode depending on the task: search, deep reasoning, voice or Imagine
- Upload a document, PDF, screenshot or photo to have it analysed in the thread
- On the web, click the plus button, choose Connectors, then Add connector to link SharePoint, Outlook, OneDrive, Google Workspace, Notion, GitHub or Linear
- On mobile, open Settings then Connectors to link the same services
- Open Settings then Data on the web, or Settings then Data Controls on mobile, to turn Improve the Model on or off and manage X personalisation
- Use the ghost icon at the top right to start a Private Chat that is never stored or used for training
- Share a conversation with the Share button, and revoke the link later from grok.com/share-links
Pros & Cons

Pricing & Plans
A permanent free plan is available at no cost and includes real-time web and X search, voice mode and connectors. The lowest published paid entry point is SuperGrok at USD 30.00 per month, with SuperGrok Plus at USD 100.00 per month. Additional tiers named SuperGrok Lite, SuperGrok Heavy, Business and Enterprise appear in the comparison table without a published price, so the effective entry point may sit below USD 30.00. Annual billing exists in the payment configuration but no annual amount is disclosed. Payments already made are non-refundable except where required by law.

Data, GDPR & hosting
A consolidated view of how Grok handles your data.
GDPR overview
Implementation is concrete and documented rather than merely claimed. The privacy policy (effective 4 April 2026) is completed by a Europe Privacy Policy Addendum (effective 24 April 2025) naming X.AI LLC as controller, setting out legal bases and listing access, rectification, erasure, objection, restriction and portability rights. A Data Protection Officer is reachable at privacy@x.ai and a single privacy portal handles requests. A public Data Processing Addendum (effective 9 June 2025) carries Standard Contractual Clauses, modules one and two, plus the UK Addendum, and commits xAI to its obligations under applicable data protection laws, GDPR included. European, UK and Swiss privacy contacts are named. One caveat is stated openly: correcting inaccurate personal data inside a model output may not be technically feasible.
Who owns the data?
The consumer FAQ states plainly that you own the inputs you submit and the outputs Grok returns, and that you may use those outputs commercially, with attribution requested under the brand guidelines. Ownership is not exclusivity, however. The terms grant X.AI LLC an irrevocable, perpetual, transferable, sublicensable, royalty-free and worldwide licence to use, copy, store, modify, publish, display and make derivative works of your content, for any purpose. That licence extends to any person's image, likeness or voice appearing in what you submit, and you warrant you hold the rights to grant it. Authorised staff may review content for product, security and legal purposes.
Reuse rights
End users may reuse their outputs freely and without asking permission, including for commercial purposes; xAI only asks that generated work be attributed to Grok as set out in its brand guidelines. Two limits are stated. Outputs are not guaranteed to be unique, so another user may receive something similar and your rights do not override theirs. And xAI may attach a disclosure marking content as generated or altered by artificial intelligence. On the publisher's side, content may serve to maintain the service, improve products, run market and customer research and train models, unless you switch training off in the data controls or use Private Chat. Business and enterprise content is never used to improve models, and data is not sold or shared for marketing or advertising.
Data retention & training
Hosting summary
xAI states that it processes all personal information in the United States, where it maintains its primary data centres, and its published subprocessor list places every named provider in the US, including AWS, Google Cloud, Oracle, Cloudflare, MongoDB, Stripe and Vercel. The Data Processing Addendum allows transfers outside Europe to the United States and other countries where xAI and its subprocessors operate. Those transfers are covered either by the EU-US, Swiss-US and UK extension Data Privacy Frameworks, or by Standard Contractual Clauses, modules one and two, approved by the European Commission, the United Kingdom and Switzerland, together with the UK Addendum. Part of the input data is shared with Brave Software so Brave search results can appear in the service, and payment processing runs through Google Payments, Apple Pay and Stripe, none of which pass card details back to xAI. Multiple geographic zones and redundant systems are described for availability. Data residency is offered only as an enterprise option.
Things to keep in mind
Risks and trade-offs to weigh before adopting Grok.
- The licence you grant over your inputs is irrevocable and perpetual, and covers any image, likeness or voice in them, so treat anything you paste as permanently licensed
- Public share links are indexable by search engines, so a conversation shared once can surface in results long afterwards
- Deliberately provocative modes and personas, including unhinged, sexy and conspiracy, are available and can produce content unsuitable for younger teenagers
- The publisher acknowledges hallucinations and declines to guarantee factual accuracy, so answers about people, law, health or money need independent checking
- Leaning on a fast, confident assistant for research and drafting can quietly erode the habit of reading sources and reasoning through a problem yourself
- Signed-out users outside the EU and UK may have no training opt-out, and voluntary feedback stays usable for training even after you opt out
- Using Grok inside X puts the exchange under X's terms and privacy policy rather than xAI's, which is easy to miss
Setup & Integrations
Technical difficulty
Very low for everyday use. There is nothing to install: open grok.com in a browser, or take the iOS or Android app, and sign in with an X account or an email address. Where permitted you can even try it without an account, though signed-out use grants xAI wider rights over what you provide. Connectors take a few clicks but require an OAuth sign-in to each third-party service. Difficulty rises only at the edges: bringing your own Model Context Protocol server assumes engineering skill, and API use means generating a key on console.x.ai.

Should you pick Grok?
Grok is a broad, genuinely multimodal assistant sitting on unusually heavy infrastructure, with the publisher claiming 300 million queries a day and a 150,000-GPU cluster. Its clearest differentiator is live retrieval: it searches the open web and X in real time and returns citations, which matters for anything time-sensitive and is the reason to prefer it over an assistant working from a frozen corpus. The free tier is unusually generous for a product of this class, keeping search, voice and connectors available at no cost, and SOC 2 Type I and II is advertised on every plan.
Data governance is legible, which is not the same as permissive. The training opt-out is real and documented, Private Chat leaves nothing behind after thirty days, the DPA is public with Standard Contractual Clauses, the subprocessor list is published and a Data Protection Officer is named. Against that, the terms take an irrevocable, perpetual and sublicensable worldwide licence over everything you submit, including any face or voice in it; all personal data is processed in the United States, with residency reserved for enterprise buyers; and no postal address appears anywhere on the site.
Two practical reservations remain. Pricing is opaque past the three individual tiers, so anyone comparing Lite, Team, Business or Enterprise has to talk to sales. And the corporate ground is still moving: xAI was acquired by SpaceX in February 2026 and the site now trades as SpaceXAI while the terms of service still name X.AI LLC. For an individual or a small team wanting current answers across text, code and media, Grok is a strong and inexpensive choice. For a regulated buyer, the licence terms and the US-only processing deserve legal review first.
