xAI Launches Grok for Microsoft Word and Deploys Grok 4.3 on Amazon Bedrock
xAI introduces a free Grok add-in for Microsoft Word that transforms notes into polished documents and integrates web research, while also making Grok 4.3 generally available on Amazon Bedrock with a massive context window.
xAI releases a free Microsoft 365 add-in called Grok for Word, allowing users to transform rough notes into structured, long-form documents directly within their workflow. The tool helps users draft proposals, fix grammar, rewrite text for clarity, and align writing styles across multiple authors without leaving the Word interface.
The Word integration also brings live web research and X data directly into documents, and it includes the ability to generate diagrams. Users leverage built-in connectors to ask Grok to draft content based on recent emails or files stored in SharePoint and Google Drive, making it a highly connected productivity tool.
Separately, xAI makes Grok 4.3 generally available on Amazon Bedrock, giving AWS users access to the model with a 1-million-token context window and configurable reasoning levels. This cloud deployment boasts the lowest hallucination rate among frontier models, making it ideal for enterprises building reliable AI agents and processing long-document workflows.
