xAI announced today the release of Grok Skills, a new feature that enables users to teach Grok once and have it retain that knowledge across every conversation. This update eliminates the need to repeatedly explain preferences, formatting rules, or workflow steps. Grok Skills are available on Grok 4.3 across the web, iOS, and Android platforms. The feature includes built-in skills for generating Word documents, creating presentations, building spreadsheets, and handling PDFs, all with full formatting and styling. Users can also create custom skills through conversation or by uploading files. According to xAI, the new Skills feature allows for the generation of production-ready documents such as invoices, pitch decks, and budget spreadsheets, with the ability to restructure, polish, or expand existing files. The feature also supports the creation of slide decks for presentations with strong visual hierarchy and speaker notes. *Source: [xai](https://x.ai/news/grok-skills)*
