ONLYOFFICE Desktop Editors v10.0 Released with Major Architecture Overhaul, Decoupled AI Tools, and Thousands of Bug Fixes

The development team behind the popular free and open-source productivity suite ONLYOFFICE has officially announced the release of version 10.0 of its desktop editors. This major milestone update arrives with a staggering tally of more than a thousand bug fixes, significant performance enhancements, a completely revamped application architecture, and a heavily expanded, highly flexible set of artificial intelligence capabilities.

Promoted by its creators as a "fully rebuilt app," ONLYOFFICE Desktop Editors v10.0 introduces substantial structural shifts under the hood. Because of this massive architectural overhaul, the development team has issued an advance warning to users upgrading from prior iterations: not all existing user settings, local preferences, and customized configurations will automatically transfer over to the new environment. This clean break reflects the depth of the engineering work required to modernize the codebase, lay the groundwork for better cross-platform stability, and refine how the suite interacts with modern computing resources and external services.

Among the most notable design shifts in version 10.0 is how the suite handles artificial intelligence. Moving away from the traditional model where AI integrations were bundled directly as a standard, pre-installed plugin within the core package, the developers have decoupled these features entirely. In ONLYOFFICE 10.0, AI capabilities are now provided via a standalone, optional "AI Tools" add-on. According to the development team, this structural change was implemented directly in response to user feedback regarding open-source builds and modularity, giving users absolute control over whether they wish to integrate heavy AI utilities into their local workspace.

For users who want to leverage artificial intelligence within their documents, spreadsheets, and presentations, the new add-on requires a simple download and installation process, for which the application provides an integrated, guided workflow. Once installed and properly configured—which can be achieved by connecting a preferred cloud provider API or by running a local large language model via tools like Ollama—the AI tools seamlessly plug into every editor across the entire suite. The development team emphasizes that because the AI natively understands the context of each individual file, its suggestions remain remarkably relevant, accurate, and contextually useful to the task at hand.

The expanded functionality of the AI add-on reaches far beyond simple text generation or basic document summaries. In the integrated PDF Editor, for instance, users can effortlessly generate concise summaries of long documents or ask specific questions regarding the document’s contents without having to manually sift through dozens of pages. In other core applications, such as the primary Document Editor, artificial intelligence can be deployed to execute sophisticated tasks, including refining text formatting, analyzing structural layouts, and automatically creating comprehensive tables of contents.

Furthermore, the updated AI Chat interface features a robust selection of preset prompts tailored to common professional workflows and daily productivity use cases. Users are not restricted to these defaults, however; they can define custom Quick Actions to execute repetitive, one-time tasks instantly, or they can set up dedicated AI Assistants. These assistants are designed to act as true collaborative editors, working side-by-side with the user in real-time as they write, edit, revise, and update the contents of a document.

Adding to its versatility, the new AI Tools add-on is now equipped to access the web and interface directly with Model Context Protocol (MCP) servers. Depending on the specific workflow requirements, this allows the system to securely pull in real-time data, glean external insights, or query information from outside sources directly inside the editing environment.

Non-AI Changes in v10.0

Beyond the major overhaul of the AI ecosystem, ONLYOFFICE 10.0 brings a comprehensive array of general improvements, user interface adjustments, and functional enhancements across its entire suite of applications.

In a shift aimed at streamlining local storage and relying on modern web-connected workflows, local document templates are no longer included out-of-the-box with the desktop application; instead, users will rely on cloud-based template options. On the visual front, Linux builds of the application benefit from refined window aesthetics, featuring reduced window border thickness and the long-awaited addition of clean window shadows to better match modern desktop environments.

Each specific editor within the suite has also received targeted improvements tailored to its unique function. The PDF Editor has upgraded its Redact tool, which is now fully capable of stripping sensitive document metadata and permanently removing unwanted annotations. Document signatures can now be added quickly and securely via the Comment tab. Additionally, the Comments panel has been redesigned to provide a comprehensive list of every annotation present in the file, accompanied by a brand-new annotation settings panel that gives users granular control over their review workflows.

In the Document Editor, handling text lists has become much smoother. Users now have dedicated options to continue an existing list or restart numbering automatically when pasting numbered items into a document that already contains a pre-existing list structure. Collaboration has also been improved; during active co-editing sessions, users can now instantly jump to another collaborator’s cursor and follow it in real-time as they work through the text. Furthermore, paragraph text formatted with exact line spacing is now clipped precisely by line, and documents written in right-to-left languages handle mathematical equations and other inline objects cleanly and as expected.

The Spreadsheet Editor introduces several power-user features designed to make data analysis more transparent and efficient. When working with formulas, the editor now highlights the exact cell ranges that a formula applies to directly within the formula bar. It also gains a convenient toggle for Auto-Complete on cell values, speeding up data entry. For compatibility purposes, spreadsheets can now be saved directly to the legacy XLS format—a particularly useful feature for professionals who frequently send files to clients or colleagues whose software environments predate modern XLSX standards. Under the hood, mathematical calculations for array formulas that reference entire columns or rows have been optimized significantly, resulting in faster processing times and substantially reduced memory consumption when crunching large datasets.

The Presentation Editor has not been left behind, receiving a variety of new print modes that mirror its updated view modes. Users now have precise control over print settings, with options to dictate whether hidden slides, slide backgrounds, frames, comments, and slide numbers should appear on printed output pages.

Get ONLYOFFICE 10.0

ONLYOFFICE Desktop Editors is free, open-source software built to run natively across major operating systems, including Windows, macOS, and Linux. Users can download the latest stable release directly from the official website. Installers for various distributions and platforms are also readily available on the project’s official GitHub releases page, which includes native packages such as a .Deb file tailored for Ubuntu, Linux Mint, and other Debian-based derivatives.

For Linux users utilizing standalone packages, automatic updates to future software versions are typically not handled out-of-the-box. However, users who prefer a hands-off approach with seamless background updates can opt to install the official ONLYOFFICE Snap package from the Snap Store instead, ensuring they always have the most current features, bug fixes, and security patches applied to their system.
