What is Grok?
Grok is an AI chat assistant built by xAI and available at grok.com and in iOS and Android apps. It answers questions, researches the web, analyzes uploaded files, and creates images and short videos. What sets it apart is direct access to live posts on X, so answers can reflect current news and trends.
Most chatbots answer from training data that stops at a cutoff date, so they struggle with breaking news and fast-moving topics. xAI pairs its language models with web search and advanced search across posts on X, so you can ask what people are saying right now. The same account covers text chat, voice conversations, image and video creation, and connectors to your email, files and calendar, which keeps research, writing and media work in one place.
Main Features
- Chat for questions, brainstorming, writing and step-by-step problem solving in math, science and code.
- Deep research that searches the web and turns a complex question into a structured answer.
- Advanced search across posts on X to surface current news, trends and public conversations.
- Imagine generates images from text, short videos with sound, and videos from your own photos.
- Voice mode for hands-free spoken conversations, with a choice of conversation styles.
- File uploads for PDFs, images, spreadsheets, code and audio, with analysis, extraction and summaries.
- Connectors for Google Drive, Gmail, Google Calendar, Outlook, OneDrive, SharePoint, Microsoft Teams and Salesforce.
- Chats, settings and your subscription stay in sync across the web, iOS and Android apps.
