At DevDay on September 29, OpenAI launched Space and Pages, two ChatGPT features that together look a lot like an office suite. Space is a shared workspace where coworkers and their AI agents keep files and documents. Pages is a word processor built for people and agents to edit together. Collaborative slides arrive "in the coming weeks," and spreadsheets are listed as coming soon with no date. The launch puts OpenAI in direct competition with Microsoft, its partner and largest investor.

What Space and Pages are

TechCrunch reports that Space is a shared area inside ChatGPT where coworkers can work with the chatbot and with their own Dots, the always-on agents OpenAI launched at the same event. We covered those in our report on OpenAI Dots. Sam Altman said pages and files sit together in Space like they would in a drive, and that spaces "feel alive." As an example, he said a user can tell a page to check a team channel and update itself with what it finds.

Pages is the document side. OpenAI describes it as a new type of document built for human and agent collaboration, and says users can write, research, generate charts and images, or visualize information inside it. Computerworld adds one detail: authors can embed "prompt" blocks, suggested prompts that readers can run to explore the document.

Some of the pieces already existed. The Promethean AI newsletter notes that ChatGPT's work tools could already create and edit documents, spreadsheets, presentations and reports, and could work with supported Google Workspace files and Microsoft Office apps. Space and Pages bring those capabilities under one roof.

What is not available yet

Slides are the next piece. OpenAI told TechCrunch that collaborative slides, which can be created by describing them in a chat, will roll out in the coming weeks. Once made, several people and agents can comment and edit them.

Spreadsheets are further out. AI Learning Guides reports that collaborative spreadsheets were announced as coming soon without a date, and points out that OpenAI offers a separate ChatGPT integration for Excel and Google Sheets in the meantime. So the full suite does not exist yet. What shipped on September 29 is the workspace and the document editor.

One figure we could not verify: a site called Technosports says the suite starts at $20 per user. We did not find that in OpenAI's own material or in the larger outlets, so treat it as unconfirmed.

The Microsoft problem

The awkward part is the relationship. Microsoft has backed OpenAI since early on, and Word, Excel and PowerPoint are among its most important products. TechCrunch frames the launch as OpenAI going after the company's bread and butter.

Microsoft is moving the other way. Computerworld says a Copilot overhaul last Friday added the ability to create and edit Office documents from within the Copilot app, and that Anthropic is also building office tools into its assistant. A commentary on Promethean AI summarizes the split this way: Microsoft put AI inside the office suite, while OpenAI is trying to build the suite around AI. That is one writer's framing, but it fits the product choices.

The two companies still work together elsewhere. OpenAI said at DevDay that it is working with Microsoft to connect specialist Dots to Agent 365, Microsoft's management layer. So this is competition between partners, not a break.

Why adoption is the hard part

Computerworld quotes an analyst, Bell, making the point that matters most. One person can start using ChatGPT for drafting or research alone, but shared documents only work if colleagues use the same environment, agree on how work is organized and trust it as the common workspace. OpenAI needs teams, not individual users.

That is a high bar. Companies have used Microsoft and Google tools for decades, and switching has costs: file formats, permissions, compliance rules, training. SparkNherd notes that ChatGPT's very large user base gives OpenAI a head start. Whether that translates into teams moving their shared files is a separate question, and nobody can answer it from a launch announcement.

There is also the question of trust with agents in shared files. If a Dot can edit a page on its own, a team needs to know who changed what and why. OpenAI has not detailed audit or version controls for Space in the coverage we reviewed. Given recent safety questions around OpenAI's models, enterprise buyers are likely to ask.

What teams can do now

A reasonable way to try it is a small pilot on a project with low stakes, such as internal research or a first draft of a proposal. Check what happens to files you already keep in Microsoft 365 or Google Workspace, and ask your admin what controls exist before letting agents edit shared documents. Wait for slides and spreadsheets before judging whether it can replace anything.

FAQ
