What Grok is

Grok is the assistant from xAI, distributed mainly through X and a standalone app. Its differentiator is access to posts on X, which makes it useful for questions about what people are saying right now — reactions to a launch, breaking discussion, sentiment on a topic — where other assistants rely on general web search. It accepts images and documents, has a reasoning mode for harder problems, and can generate images. Because it is tied to X, a subscription already held for that platform may include it, which changes the cost comparison with a separate assistant. The limits are availability and evidence: features reach higher subscription tiers first, the reliance on X makes it strong on social discussion and weaker on structured or academic sources, and answers still need verification. A companion mobile app carries the same access, and the API exposes the model for programmatic use.

Academic or regulatory research needing authoritative sources
Teams that need a neutral, source-cited answer

Features gated by subscription tier
Answers are not citation-first

Pricing in detail

A small free quota exists, and fuller access is bundled with X subscription tiers rather than sold only as a separate product; a standalone subscription and API access are also offered. Because the assistant is tied to the platform subscription, the effective cost depends on whether you already pay for X. Compare the marginal cost of the tier that includes it against a separate assistant subscription.
