ONLYOFFICE is an open source office suite for collaboration on documents, spreadsheets, presentations, and PDF files. It focuses on safeguarding user data at multiple levels from its open-source code, which allows anyone to review and verify the software’s integrity, the server-side version, data encryption in transit, and at rest to password protection and flexible permissions.
Enabling AI features via a plugin
In today’s environment, there is increasing concern about how data is used to train AI models. While artificial intelligence is becoming a vital part of everyday digital work, these concerns should not be overlooked. Recognizing that AI is already an essential tool for many professionals, ONLYOFFICE has introduced an AI assistant for document management that works as an optional plugin. This design ensures that the AI features are only activated if a user chooses to use them. With this approach, users are not forced to share their data with external AI systems unless they opt in.
When the plugin is in use, the user gets to select which AI model and provider should process their data. This means that, if staying within the open-source segment is a priority, users can choose to work with models like Mistral—a recognized open-source model—or switch to alternatives like Ollama.
Furthermore, the system supports the option of connecting a local AI model. This flexibility ensures that users who prefer to keep all processing on their local machines or private servers can do so. Such a configuration mitigates risks associated with external data sharing and aligns with the principles of data sovereignty and privacy that are central to responsible AI practices.
Using AI for smarter document editing
By leveraging artificial intelligence, users can quickly summarize and rewrite text, translate, and analyze word usage—all from within an open-source platform.
• Ask AI
• Summarize
• Generate text
• Make text shorter or longer, or rewrite it differently
• Translate text
• Analyze words and text
• Fix spelling and grammar

By housing AI functionalities within a plugin, ONLYOFFICE keeps these features separate from core operations. The user must actively choose to enable and configure them, including selecting a trusted model provider.
Balancing AI innovation with user privacy
The AI integration in the ONLYOFFICE suite is a pragmatic solution that acknowledges both the necessity and challenges of modern technological developments. As AI technologies become more embedded in everyday tools, the responsibility to protect user data grows. ONLYOFFICE addresses these concerns by offering a system where AI enhancements are optional and fully configurable. Whether a user opts for open-source solutions like Mistral, chooses a provider such as Ollama, or even integrates a local model, the ultimate decision rests with the user.
The AI plugin is available both in the cloud and desktop versions of ONLYOFFICE. You can use it across different environments — in ONLYOFFICE Docs, Desktop Editors for Windows, Linux and macOS, and DocSpace — ensuring a seamless AI-powered experience no matter where you work.
