OpenAI Challenges Microsoft Office With ChatGPT Space, Pages and Slides
OpenAI launches ChatGPT Space, Pages and collaborative Slides, challenging Microsoft Office with AI workspaces, documents and presentations for office teams.
Summary
At Dev Day in San Francisco on Tuesday, September 29, 2026, OpenAI launched ChatGPT workplace tools for office workers. Space is a shared workspace where coworkers collaborate with ChatGPT and Dots, newly launched AI agent personas that perform tasks for users. Pages and files sit together like a drive, while individual pages can follow instructions, such as checking a team channel and updating their content, CEO Sam Altman said.
Pages, positioned against Microsoft Word and Google Docs, supports writing, research, charts, image creation and information visualization through human and agent collaboration. Collaborative Slides, OpenAI’s answer to PowerPoint, generates presentations through ChatGPT conversations, then lets multiple workers and agents edit and comment. Slides remains unavailable and will roll out in the coming weeks. The expansion moves longtime Microsoft partner OpenAI into Microsoft’s core workplace software market as Microsoft and Salesforce, responding to the same industry shift, release their own AI products.
