Grok is xAI’s general-purpose AI assistant for conversation, research, file analysis, image and video creation, voice interaction and real-time search. It is available through grok.com and mobile apps, and a version is also integrated into X.
What is Grok?
Grok is the product people use to interact with xAI’s models. It should be distinguished from the Grok model family itself: the models provide the underlying intelligence, while the Grok app adds the interface, search, file uploads, voice, connectors and subscription features.
What can Grok do?
According to xAI’s official documentation, Grok can answer questions, brainstorm, write, analyze PDFs, images, spreadsheets, code and audio, and search the web and public posts on X. Grok Imagine adds image and video generation, while voice mode supports hands-free conversations. Connectors can bring email, files and calendars into a chat where available.
These capabilities make it broader than a text-only chatbot, although availability and usage limits depend on the plan, platform and region.
Who is it best for?
Grok is useful for people who want one assistant for current web information, public X content, writing, file analysis and media generation. Its real-time search can be valuable when recent information matters, provided the user still checks the cited or underlying sources.
It is not suitable for decisions that require guaranteed accuracy, and sensitive information should not be shared without reviewing the policy that applies to the exact account and workspace.
Pricing and access
xAI offers a free plan. When checked on September 20, 2026, SuperGrok was listed at $30 per month and SuperGrok Plus at $100 per month. Paid plans increase limits and unlock additional access, while Business and Enterprise plans add workspace, administration and data controls. Prices and entitlements can change, so the official pricing page is the final reference.
Strengths and limitations
Grok combines live web and X search with chat, file analysis, voice, image generation and video generation. This makes it flexible for research and creative work. Its cross-platform account also keeps conversations, settings and subscriptions synchronized.
Its main limits are familiar to generative AI: answers may be incomplete or wrong, live sources may vary in quality, and features differ across plans. The integration with X also creates a separate privacy context that users must understand.
Privacy and data use
X states that public X data and interactions with Grok on X may be shared with xAI for training and fine-tuning, and provides a setting to opt out. xAI publishes separate terms for Grok services and business workspaces. Business and Enterprise plans advertise no training and additional data controls.
In short
Grok is xAI’s multimodal assistant for chat, live search, files, voice and media creation. Its strongest differentiator is access to current web and X information, while its limits require source checking and careful privacy choices.
