ONLYOFFICE Docs is an open-source online office suite that brings document editing and real-time collaboration into the business platforms you already use, e.g. DMS, CMS, e-learning systems, CRMs, intranets and file storage solutions. Using it, you can view, edit and co-author text documents, spreadsheets, presentations, digital forms, diagrams and PDF files directly in your browser.
ONLYOFFICE Docs is built for seamless integration in any business environment:
· 40+ official connectors for popular platforms, including Nextcloud, ownCloud, Moodle, SuiteCRM, Redmine, Alfresco, Confluence, WordPress, Drupal, Odoo, Jira, Mattermost, HumHub, Plone, Pipedrive, SharePoint, Strapi and more.
· An open API and WOPI compatibility, making it easy to embed into virtually any web-based application.
ONLYOFFICE Docs works well for teams and organizations of any size, but it’s also a strong option for software developers and SaaS providers. You can integrate it into your own product and deliver document editing and collaboration to customers—including the ability to offer it under your brand.
When integrated with your platform, ONLYOFFICE Docs allows you to:
· Create and edit documents, spreadsheets and presentations with professional formatting tools;
· Create and fill PDF forms with interactive fields;
· Edit, annotate, redact and co-author PDF files;
· Open Visio diagrams for viewing;
· Collaborate in real time with two co-editing modes, comments, @mentions, Track Changes, version history and document comparison;
· Enable audio/video conferencing via the Jitsi plugin and communicate in the built-in chat while editing;
· Extend functionality with plugins, such as Google Translate/DeepL translation, text-to-speech, Zotero/Mendeley bibliographies, and LanguageTool proofreading.
One of the key features of the suite is its flexible AI integration. Unlike other popular office tools, ONLYOFFICE doesn’t provide any predefined AI assistant. Users can connect their favourite AI services (e.g., ChatGPT, DeepSeek, Mistral, Google Gemini or even local AI models via Ollama) and use multiple assistants at once for tasks like content generation, summarization, translation and grammar correction in documents, data analysis in spreadsheets, slide generation in presentations and OCR in PDFs.
ONLYOFFICE Docs natively supports Microsoft Office formats—DOCX, XLSX, PPTX—so teams can work with Word, Excel, and PowerPoint files without compatibility issues. It can also open Apple iWork formats (Pages, Keynote, Numbers) for viewing and convert them to DOCX/PPTX/XLSX for editing. In total, it supports 60+ file formats.
Before using ONLYOFFICE Docs in your team, you can choose what fits your needs:
· Self-hosted on Linux or Windows servers for full control over your data;
· Cloud-based ONLYOFFICE Docs Cloud for an out-of-the-box option ready for integration.
ONLYOFFICE also offers free desktop apps (Windows, Linux, macOS) for offline editing and free mobile apps (Android, iOS) for working on the go.
