Microsoft is looking at OpenAI's GPT for Word, Outlook, and PowerPoint - The Verge

If Microsoft leans more towards building in functionality that's present in ChatGPT, the conversational AI that made headlines last year, then Outlook could compose entire emails based on simple queries. Imagine Outlook writing an email to your colleagues explaining you're unwell, based purely on a "write an email to my team explaining I'm out sick" query. Microsoft is also reportedly planning to launch a version of Bing that uses ChatGPT to answer search queries. This new feature could be available as soon as March, in a bid to make Bing more competitive with Google.
