SAN FRANCISCO — xAI launched Skills for Grok on May 18, 2026, turning the AI assistant into a platform that remembers what users teach it. The update is live across grok.com, iOS, and Android for Grok 4.3 users.
What Skills Does
The core premise is straightforward: teach Grok something once and it retains that knowledge across every subsequent conversation. No more re-explaining preferred formats, workflow steps, or recurring instructions. Once a skill is defined, it persists — eliminating the repetitive setup that has long been a frustration with AI assistants.
Every Grok account ships with built-in skills from xAI, activated without any configuration required. Users can override any built-in skill with a customized version, and their personal version always takes priority.
Office Document Generation
Among the most practical built-in capabilities is Grok's ability to produce production-ready office documents. Users can request formatted invoices, contracts, and proposals in Word; pitch decks and workshop presentations in PowerPoint; budget trackers and financial models in Excel; and polished research papers and reports as PDFs.
The documents arrive ready to open and share — including full formatting such as headings, tables, formulas, and consistent styling — rather than raw text that needs to be manually pasted into another application.
Building Custom Skills
Creating a personal skill takes seconds. Users describe the task in conversation, upload a reference file, or write instructions from scratch. If a formatting standard or workflow has already been established over the course of a session, users can simply ask Grok to save everything it learned as a skill — ensuring the same approach applies automatically to every future conversation.
