Grok

Grok is an AI chatbot and chat application developed by xAI, the AI company founded by Elon Musk. Available on web, iOS, and Android, Grok is positioned as a general-purpose conversational AI with real-time web search, image and video generation, and voice interaction capabilities. The base product is free to use, with an upgraded subscription tier called SuperGrok offering expanded limits and additional features.

What It Is

Grok is a large language model–powered chatbot that handles a wide range of tasks: answering questions, assisting with creative and specialized work, generating images and videos, and searching the web in real time. It operates as both a standalone web app at grok.com and a mobile app on iOS and Android. xAI describes it as a "free AI chatbot and chat app" designed for everyday use as well as more demanding tasks.

Core Capabilities

Grok's feature set spans several modalities:

• Real-time web search — Grok can search the web live to surface current information rather than relying solely on a training cutoff.
• Image and video generation — Users can generate AI images and videos directly within the chat interface, including an HD 720p, 30-second video option on the upgraded plan.
• Voice chat — Grok supports voice-based interaction as an AI voice chatbot.
• File uploads — Users can upload files to give Grok additional context for smarter responses.
• Customizable responses — The FAQ notes that users can customize how Grok responds.
• Shared links — Conversations can be shared via links.

Model Architecture and Agents

Grok is powered by xAI's own model family. The FAQ references multiple models with distinct features. The SuperGrok tier unlocks an "Expert mode" that deploys up to four AI agents collaborating to produce answers, a multi-agent approach xAI describes as designed to get users "the best answers." The base free tier provides standard single-model chat.

Platform and Access

Grok is accessible via:

• Web at grok.com
• iOS mobile app
• Android mobile app

The FAQ notes that subscription access may not automatically carry across all devices and that users may need to link accounts. A community forum is hosted on Discord, and legal terms and privacy policy are published at x.ai/legal.

The FAQ page and feature set indicate an actively developed product with ongoing capability additions across chat, image, video, and voice modalities.
