ONLYOFFICE 10.0: AI Tools, New Apps and a Security Upgrade Explained
Quick answer: ONLYOFFICE 10.0 is the autumn 2026 update of the ONLYOFFICE office suite. Its biggest changes are AI tools built right into the document, spreadsheet, presentation and PDF editors, four new free Apps (AI Agents, Forms, Files and Rooms), and fixes for 35 security problems. It also adds about 50 new features and more than 1,000 bug fixes across online, desktop and mobile editors.
If you have ever copied a paragraph out of a document, pasted it into a separate AI chatbot, waited for the answer, and then pasted it back, you already know the problem. It works, but it is slow and a bit messy. ONLYOFFICE 10.0 tries to fix exactly that by putting the AI inside the editor where you already work.
In this post, I will explain what is new in simple words, show you a realistic example of how a small team might use it, and help you decide if it is worth your attention.
What Is ONLYOFFICE 10.0?
ONLYOFFICE is an office suite. Think of it as a set of tools for writing documents, building spreadsheets, making presentations and working with PDFs. Many people and companies use it as an alternative to the more famous office tools, and it works in the browser, on desktop and on phones.
ONLYOFFICE 10.0 is the big autumn update. According to the release announcement, it includes around 50 new features and more than 1,000 fixes. The three headline changes are easy to remember:
- AI tools inside every editor
- Four new free modular Apps
- A major security upgrade
Let us go through each one.
ONLYOFFICE AI Features: Help Without Leaving Your File
The main idea behind the ONLYOFFICE AI features is simple. The AI should understand the file you are working on, so you do not have to explain everything from scratch. The editors now have a dedicated AI tab with a built-in chat. From there you can write a first draft, summarize a long text, translate it, clean it up and format it, all without leaving the file.
Here is how the announcement describes the everyday uses:
- Legal teams can summarize contracts.
- Analysts can generate forecasts or Pivot Tables.
- Managers can turn rough ideas into a structured presentation.
There are also ready-made prompts, custom AI actions, assistants and saved prompts. This matters more than it sounds. If your team asks the same kind of question every week, you can save the prompt once and reuse it instead of typing it again.
You Choose the AI Model
This part is important for companies that care about privacy. Organizations decide which AI model to use, based on quality, speed and cost.
- Cloud users can switch on ONLYOFFICE AI through OpenRouter, a service that gives access to many AI models.
- Companies that run their own servers can connect any model they like, including local ones that run on their own hardware.
The release notes say sensitive data stays within your own infrastructure. In plain words, if you run a local model on your own server, your documents do not need to travel to an outside company to get AI help.
A Realistic Example: How a Small Agency Could Use AI in Document Editors
Ideas are easier to understand with a story. Here is an example of how AI in document editors can save time. This is an illustrative scenario, not a real customer case.
Meera runs a 12-person marketing agency. It is Monday morning and three things are waiting for her:
- A 14-page client contract that she needs to understand before a call at 11.
- A sales spreadsheet with six months of numbers that her boss wants summarized.
- A pitch deck for a new client that is due on Friday and currently exists only as a messy list of ideas.
In the old way, Meera opens a separate AI chatbot, copies the contract text in, copies the answer back, and repeats this for each task. Along the way she worries about whether she should be pasting a client contract into an outside tool at all.
With the AI tab in the editors, her morning looks different:
- Contract: She opens the contract and asks the built-in chat for a short summary of key dates, payment terms and anything that looks unusual. She then reads those parts of the contract herself to confirm them.
- Spreadsheet: In the sales file, she asks for a Pivot Table by product and month, and a simple forecast for next quarter.
- Presentation: She pastes her rough ideas into a new deck and asks the AI to turn them into a structured set of slides.
She still checks everything. AI can make mistakes, and the final decision is always hers. But the copy and paste loop is gone, and she gets a solid starting point in minutes instead of hours.
ONLYOFFICE Docs Apps: Four New Free Add-Ons
The second big change is a set of four modular ONLYOFFICE Docs apps. They are free and released under the AGPL v3 license, which is an open source license. Each one adds a new ability to ONLYOFFICE Docs:
| App | What it does |
|---|---|
| AI Agents | Automates parts of your workspace with smart search, a personal knowledge base and extended reasoning. It is powered by MCP servers. |
| Forms | Helps you collect data and then analyze the responses. |
| Files | Keeps your documents in one place with access controls. |
| Rooms | Supports safe teamwork, including Virtual Data Rooms for confidential content. |
A quick note on two terms. MCP stands for Model Context Protocol, a common way for AI tools to connect to other tools and data. A Virtual Data Room is a protected online space where sensitive files, such as deal papers, can be shared with chosen people only.
Setting them up is easy. In the cloud, the Apps are on by default. On your own server, a single command installs them.

Why a Secure Office Suite Matters More Now
A secure office suite is not a luxury when your files hold contracts, salaries, client data and legal papers. ONLYOFFICE 10.0 fixes 35 security vulnerabilities. A vulnerability is a weak spot that someone with bad intentions could try to use.
The announcement ties this to the fact that AI-driven threats keep growing, so protection for organizations that handle sensitive data needs to keep up. The privacy choices around AI (local models, your own infrastructure) and tools like Rooms and metadata removal point in the same direction. If your team can update, it is a good idea to do so and read the official security notes.
Desktop and Mobile: What Changed
Desktop Editors get a refreshed homepage, redesigned Templates and Clouds sections, an Odoo integration and visual improvements on Linux. In Desktop Community, the AI tools are available as an optional add-on.
The free iOS and Android apps add an AI assistant with new providers such as Grok and DeepSeek, AI AutoFill for forms, and voice input, which is useful when you are working on the go.
Should You Care About ONLYOFFICE 10.0?
This update is most useful for:
- Small teams and agencies that want AI help without juggling extra tools
- Companies with privacy rules that prefer to run their own AI models
- Legal, finance and operations teams that handle long documents and many numbers
- Self-hosters and open source fans who like to control their own servers
It may matter less if you only write a few simple documents each month. Also keep in mind that AI output always needs a human check, and features can differ by edition (cloud, server, desktop community), so confirm what is included in your setup before you plan around it.
