AI moves into the editors
ONLYOFFICE says context-aware AI is available in its document, spreadsheet, presentation and PDF editors. A dedicated AI tab with built-in chat is intended to help users draft, summarize, translate, clean up and format content without switching away from the file. 4
Organizations can choose models based on factors such as quality, speed and cost. The announcement says cloud users can connect through OpenRouter, while server deployments can connect to different models, including locally hosted ones. ONLYOFFICE presents local models as an option for keeping AI processing within an organization’s infrastructure; that should not be read as a guarantee about data handling when using a cloud model. 4
Four apps extend ONLYOFFICE Docs
The release introduces four apps that add functions around the editors. The company describes them as free apps extending AGPL v3–licensed ONLYOFFICE Docs. 5
- AI Agents are described as supporting workspace automation, intelligent search and personalized knowledge bases, with MCP server support.
- Forms are for collecting information and analyzing responses.
- Files provides centralized document storage and access controls.
- Rooms supports collaboration, including virtual data rooms for confidential material.

The announcement says the apps are enabled by default in the cloud version and can be installed on server deployments with a single command. These are vendor-described availability and deployment details, not independent evaluations of how the apps perform in a particular environment. 5
PDF, collaboration and mobile updates
The release highlights several changes across the editors and mobile apps:
- PDF editing: New features include metadata removal, customizable annotations, automatic table recognition and reusable signatures.
19
- Document collaboration: ONLYOFFICE highlights the ability to follow teammates’ cursors while co-editing.
30
- Presentations and spreadsheets: The company also points to faster spreadsheet performance and exporting presentations as GIFs or videos.
- Mobile AI: The free iOS and Android apps are reported to add an AI assistant with Grok and DeepSeek providers, AI form autofill and voice input.

These examples cover some of the release’s announced changes, not every feature included in the roughly 50-feature count. The supplied release excerpts do not give enough detail to assess each change’s availability across specific editions or devices.
What the security figures mean—and don’t mean
ONLYOFFICE reports that version 10.0 fixes about 35 vulnerabilities, alongside more than 1,000 bug fixes overall. 2 That is a release figure from the company; on its own, it does not show the severity of the vulnerabilities, how they were assessed or whether the update has been independently audited. Nor does the count establish broad protection against AI-related threats.
The company previewed the autumn release on September 10, 2026, and its version 10.0 release blog is dated October 10. 21
2 For organizations considering an upgrade, the most useful next step is to verify the specific editor, deployment model and AI-provider configuration they plan to use.
