Grok 4.5 arrives on iOS, Android, the web and X
Grok 4.5 is now available on the web, X, and the Grok apps for iOS and Android. xAI says it improves conversation tracking, response clarity, and the ability to create spreadsheets, presentations and written content, while also integrating with Microsoft 365.
xAI now offers Grok 4.5 across all its main access points: the grok.com website, X, and the iOS and Android apps. The model is available today, according to the company.
The update is designed to help Grok better understand what you are actually asking, maintain context during longer conversations, and respond with greater clarity and reliability. It also promises to handle complex questions more efficiently, delivering answers in less time.
What you can do with Grok 4.5
The model is designed for everyday tasks, not just answering questions. You can ask it to:
- Explain a topic you are unfamiliar with.
- Compare an important purchase.
- Plan a trip.
- Research a subject and summarize its main points.
- Extract key information from a long PDF.
Grok 4.5 can also turn an idea into a more complete result. According to xAI, it can create a functional spreadsheet, turn an outline into a presentation with slides and diagrams, or write clear copy. The company says these tasks work both on computers and phones.
That changes the kind of help you can expect from a chatbot. Instead of only giving you instructions for preparing a presentation or table, Grok can build a first version that you then review and adjust.
It also works inside Microsoft 365
Grok is available directly in Word, Excel, PowerPoint and Outlook through Microsoft 365 add-ins. In practice, this lets you use the model inside tools you already use to write documents, work with data, prepare presentations or manage email.
The difference between accessing Grok from a separate app and using it inside these programs matters: the assistant is closer to the work you want to do. Its results still need review, especially when they involve figures, important decisions or documents that will be shared.
Grok 4.5's arrival on the web, X, iOS and Android makes this version the standard Grok experience instead of limiting it to a single product. What to watch now is how it performs on longer tasks and whether its ability to create files and documents remains consistent outside the company's demonstrations.
