ChatGPT adds a Microsoft Word sidebar on every plan
OpenAI released a ChatGPT add-in for Microsoft Word that can draft from notes, summarize a document, revise selected text, and adjust headings and formatting from a sidebar. OpenAI says it is available on every ChatGPT plan through Microsoft Marketplace, with plan token limits and shared premium-feature allowances still applying.
Why it matters: ChatGPT can now act directly inside a high-volume document workflow rather than through copy and paste. That saves context switching, but it also makes document scope, selected text, usage limits and change review part of the control boundary.
