Grok

The comparison table on the x.ai pricing page gives Free the same Grok 4.6 model as paid tiers, plus image generation, the web and mobile apps, Grok Build and connectors. Real-time web and X search is marked Limited rather than included in full. Video generation, Expert mode and Grok Bot are not part of Free.

The page publishes no daily message or image count for any tier. The terms instead reserve the right to apply rate limits at SpaceXAI’s discretion, so the practical free allowance can change without a new price table. Treat Free as a way to test tone, search quality and image style before deciding whether video or Expert mode is worth paying for.

The tiers differ mainly in usage headroom, video resolution and extra agents. Editorial assessment: choose SuperGrok when you need video or Expert mode regularly, and only consider Plus if 1080p output or peak-time priority is a working requirement rather than a preference.

• SuperGrok Lite, $10 a month: video, Expert mode and 2x longer conversations.
• SuperGrok, $30 a month: Grok Bot, 5x longer conversations, 720p clips of up to 30 seconds and longer voice sessions.
• SuperGrok Plus, $100 a month: 1080p video, significantly higher usage and priority access.
• SuperGrok Heavy, $300 a month: highest usage, a larger agent team and X Premium+ included.

Heavy is the only tier that bundles X Premium+ at no extra cost, and the plans page says you claim it by connecting your X account. Signing in with X, Google or Apple lets SpaceXAI access and store information that service shares, which may include access tokens.

Features that send content to X or read content hosted there count as your instruction to share it. The privacy policy says information shared with third parties such as the X platform is then governed by that platform’s own terms. Review what a connector can read before linking a work account.

The terms say you keep ownership of your inputs and outputs, as between you and SpaceXAI. You also grant SpaceXAI an irrevocable, perpetual, sublicensable and worldwide right to use, modify, publish and make derivative works of that content for any purpose, including product improvement and market research. The same grant covers any person’s image, likeness or voice in the content.

When signed in, you can choose whether your content is used to improve products and train models. That is a setting, not a contractual exclusion: the pricing table lists a no-training commitment only for Business and Enterprise. Keep client documents and unreleased work out of consumer Grok unless the opt-out has been set first.

Output ownership stays with you under the terms, but two conditions come with it. You may be required to apply, or SpaceXAI may apply, a disclosure that content was generated or altered by AI, and you agree to keep such disclosures. Outputs are not guaranteed to be unique, so another user can receive a similar image.

Uploading a photo or recording of a real person requires all the permissions and consents needed for SpaceXAI to use it, under the same broad license. Use your own likeness, or a person who has agreed in writing, and do not edit images of public figures or private individuals without that consent.

Paid subscriptions renew automatically until cancelled, and cancellation can happen at any time. Payments already made are non-refundable except where the law requires otherwise, and there is no refund if SpaceXAI suspends or terminates an account. If a payment fails, the account may be downgraded or suspended until it is paid.

SpaceXAI may raise prices with reasonable notice in the app or by email, and the new price applies at the next renewal, giving you the chance to cancel first. Disputes are governed by Texas law, with a class action and jury trial waiver where permitted.

1. Record the date, plan and whether search reported a limit.
2. Request the brief with a rule that every factual sentence needs a link.
3. Open each link and check that it says what the sentence claims.
4. Ask one follow-up that separates confirmed facts from reactions on X.
5. Note any claim that appears only in posts, not in primary sources.

Accept a brief whose every factual sentence is supported by an opened source and whose X reactions are labelled as such. Reject invented quotes, dead links or claims attributed to the wrong account. Leave the observed result blank until the exercise is run.
