Microsoft's Gaming Copilot AI assistant is officially coming to Windows PCs and the Xbox mobile app. The company has been testing the tool for PCs with Xbox Insiders, but now it's getting a broader rollout.To that end, it'll be available to players aged 18 and older on the PC Game Bar. The Xbox app version rolls out this October, for both Android and iOS, after a beta test took place earlier this year. Microsoft says that its Gaming Copilot will be available throughout the globe, except in mainland China.So what exactly is this thing? It's sort of like an AI version of those old Nintendo help phone lines. The chat box appears as an overlay on the screen and players can use it to ask questions or to get tips about a game. The company says it "knows what you're playing and understands your Xbox activity," as it uses in-game screenshots. It can also answer questions about an Xbox account and offer recommendations on stuff to buy.The official version also offers voice chat, so you can just ask the questions out loud. On PC, there's a "Push to Talk" hotkey that activates the bot, which is handy. The app includes a microphone button. There's a widget for the PC build that can be placed anywhere on the screen. This is useful for longer conversations.
