Most office suites stick AI in a sidebar. ONLYOFFICE Docs 10.0 takes a different approach: the AI lives inside each editor—document, spreadsheet, presentation, and PDF—and reads the file you're working on. The shift sounds small, but it eliminates the copy-paste ritual that makes external AI assistants feel bolted-on.
Version 10.0 also delivers around 50 new features, more than 1,000 bug fixes, patches for roughly 35 security vulnerabilities, and introduces modular apps that let teams switch on only what they need.
Key facts
- AI tools live in a dedicated tab inside each editor and read the open file.
- Users can pick their AI model—ChatGPT, Claude, Gemini, xAI, or a local model on a self-hosted server.
- Modular apps add AI Agents, Forms, Files, and Rooms as separate toggles.
- Available on Windows, macOS, Linux, iOS, and Android, with cloud and self-hosted options.
- Released under AGPL 3.0, with more than 40 platform integrations including Nextcloud and WordPress.
Background: where ONLYOFFICE fits
ONLYOFFICE Docs is an open-source office suite that handles documents, spreadsheets, presentations, PDFs, and fillable forms. You can run it via ONLYOFFICE Cloud, self-host it on your own servers, or integrate it with platforms like Nextcloud, Moodle, Box, and WordPress. Desktop apps cover Windows, macOS, and Linux; mobile apps cover iOS and Android.
AI that reads the file
The AI Tools tab sits in each editor. Open it and you get a chat box with preset prompts. Since the AI reads the open file, you skip explaining context—the tool already knows what you're working with.
Capabilities vary by editor:
- PDF Editor**: Ask questions and get direct answers, generate a one-click summary, draft an email based on the document, or redact sensitive information. Best for reports, contracts, or any text-heavy file.
- Document Editor**: Summarize, rewrite, simplify, translate, proofread, extract key points, build a table of contents, suggest titles, and apply formatting.
- Spreadsheet Editor**: Generate formulas with plain-language explanations, spot trends, build forecasts and Pivot Tables, clean inconsistent data, flag outliers, and fill gaps.
- Presentation Editor**: Turn a single idea into an outline, suggest slide titles, draft bullet points, shape structure, and generate speaker notes.
Reusable tools include quick AI actions for one-off tasks, AI assistants that run continuously as you edit, and saved prompts in AI Chat. At launch, quick AI actions and AI assistants are Document-Editor-only; saved prompts and AI Chat work more broadly.
Model flexibility
ONLYOFFICE doesn't lock you into a single provider. Cloud users can enable the ONLYOFFICE AI service (powered by OpenRouter) with no setup. Self-hosted users connect any compatible model—including one running locally. You can set a default model and assign different models per task, such as a fast model for rewrites and a more capable one for analyzing large datasets.
For regulated industries—government, healthcare, legal, finance—local models keep sensitive files off external servers. ONLYOFFICE has also removed built-in AI from open-source versions; AI installs separately if you want it.
Who should care
| User type | Why ONLYOFFICE 10.0 matters |
|---|---|
| Privacy-focused teams | Local AI models keep documents on your own infrastructure—no external data transmission. |
| Small teams with limited budgets | AGPL 3.0 license, self-hostable, modular so you don't pay for unused features. |
| Organizations already using Nextcloud/ownCloud | Ready-made integration; you can swap Microsoft tools for an open-source stack. |
| Developers or power users | Choose and swap AI models, self-host, and customize your setup. |
| Enterprises needing compliance controls | Modular apps let you disable features you don't want exposed—smaller attack surface, simpler auditing. |
Our analysis
The core trade-off is freedom versus hand-holding. Microsoft 365 Copilot integrates tightly but ties you to Microsoft's models and ecosystem. ONLYOFFICE's pitch is "bring your own model, run it where you want." The cost: you're responsible for setup, model configuration, and ongoing maintenance if you self-host. For some teams, that's a feature; for others, it's a burden.
Modular apps matter more than they first appear. Most office suites are all-or-nothing. Letting a small team disable Rooms or Forms trims both UI clutter and potential security surface area. This thinking mirrors how Nextcloud and ownCloud users already build their stacks—compose only what you need.
Watch for three things: whether quick AI actions expand beyond the Document Editor, how the local-model workflow performs on modest self-hosted hardware, and whether ONLYOFFICE's AI tooling matures to close the gap with Copilot's polish.
Bottom line
ONLYOFFICE Docs 10.0 is the most credible open-source answer if you want AI that understands your file rather than a chatbot you paste text into. The flexibility to pick your model and hosting setup is genuine—but only if your team has the capacity to configure and maintain it.
Key takeaways
- AI runs inside the open file rather than a side panel, so context comes free.
- Self-hosted setups can plug in a local model, keeping data on your own hardware.
- Modular apps let teams enable only the tools they use.
- Version 10.0 ships desktop builds for Windows, macOS, and Linux, plus iOS and Android apps.
