What to configure next

There is no required order — pick what is relevant to your setup:

• Set up collaboration — configure co-editing modes (Fast for real-time changes, Strict for save-on-demand), sharing permissions, and real-time communication → Collaboration
• Connect an AI assistant — set up a local model (LocalAI, LM Studio, Ollama) or an online provider (Anthropic, DeepSeek, Google Gemini, GroqAI, Mistral AI, and others) to get writing assistance directly inside the editors → Artificial intelligence
• Add plugins — extend editor functionality with ready-made or custom plugins, installable through the Plugin Manager without restarting the editors → Plugin Manager
• Customize the interface — white labeling and branding options → Installation and configuration
• Secure your installation — review the security guide → ONLYOFFICE Docs: Security checklist
• Check supported formats — see the full list of open and proprietary formats supported by the Document Editor, Spreadsheet Editor, Presentation Editor, and PDF Editor
