You can now talk to Microsoft's Bing chatbot from your keyboard in iOS with SwiftKey - The Verge

A keyboard-AI integration is not necessarily a new idea. There are other apps that offer similar functionality, like ParagraphAI, Smart Typer, and Typly. But it's part of a growing trend in which AI becomes an intermediary for communication. It's not clear how popular these apps will be (in my experience, AI-assisted editing is tricky to navigate on a small phone screen), but from Microsoft's perspective, it's another opportunity to insert itself into our technological lives, usurping a position currently occupied by rivals like Google and Apple.
