Editor's Verdict
AI Office earns a 3.8/5 rating as one of the more capable options in the ai document creation space. Its standout strength — integrates with internal chat and document knowledge for context-aware generation — makes it particularly valuable when that capability matters most to your workflow. The main trade-off is requires an ultimate plan subscription to access ai features, which is worth weighing against the alternatives before committing. If that trade-off fits your use case, the paid plans offer a predictable monthly cost that scales with team size.

What is AI Office?
AI Office is an AI document creation tool from Chat&Messenger that helps users create, edit, and review business documents compatible with PowerPoint, Excel, and Word formats. It is designed for teams who want to leverage internal company knowledge, such as chat history and existing documents, to generate drafts and improve content. The tool integrates into the Chat&Messenger all-in-one groupware platform, allowing users to collaborate in real-time without needing a local Microsoft Office installation or license on their devices. Users can import existing .pptx, .xlsx, and .docx files for editing. Pricing is available under the Ultimate plan, with cloud versions starting at 1,000 yen per user per month and on-premises versions at 600 yen per user per month, based on annual contracts. The service supports Windows, Mac, Android, iOS, and Web browsers.
Who is AI Office for?

How to get started with AI Office
A practical, five-step path we recommend for anyone evaluating AI Office for the first time — designed to minimise wasted time and help you decide fast.
1Sign up for AI Office
Head to the official AI Office website and create an account. Most paid plans offer a trial or money-back window — check the pricing page before committing.
2Set up your workspace
Install the app on web if a native client is available, or simply open it in your browser. Configure basic preferences such as language, notifications, and default output style so that subsequent runs feel consistent.
3Run your first task with AI Assistant for consulting and document creation
Start with a small, low-stakes task to understand how AI Office responds. Write a clear prompt or input, review the output, and iterate. This low-risk exploration is the fastest way to build intuition for what the tool excels at.
4Integrate into your daily workflow
Once you know its strengths, introduce AI Office into one concrete workflow — not ten. Replace one existing step with it and measure the time saved or quality gained over a week before expanding usage further.
5Upgrade based on real usage
Rather than upgrading upfront, monitor which limits you actually hit (message count, output length, export features). Upgrade only when a specific limit blocks your productivity, not because the higher plan looks more attractive on paper.
