Work, Share, and Sync — Simply and Securely
Sync-in simplifies access, sharing, and collaboration across devices and users — while giving you total control and security.

Collaborative Spaces
Provide your teams with dedicated spaces to collaborate and organize their data. Created autonomously, these spaces reduce administrative overhead and ensure long-term access to information. Leveraging the anchoring feature, users can link their files without duplication while maintaining full control. Each member or group accesses the space with fine-grained permissions, defined according to their role or responsibilities. Naturally compartmentalized, the spaces offer a high level of security and support compliance with regulatory requirements.
Synchronization
Applications for Windows, macOS, and Linux enhance the capabilities of the web interface by automatically syncing files between your computer and Sync-in. Easily connect to multiple servers and manage your synchronizations with advanced options: direction, frequency, simulation mode, detailed logs… A simple, powerful, and secure solution to stay perfectly in sync !
Shares
Securely share your files, both internally and externally. Collaborate in a structured and consistent way by setting granular permissions. For occasional exchanges, use secure links and apply precise rules: access limits, expiration dates, password protection… Maintain full control over the distribution and use of your documents.
Guests & Personal Groups
Collaborate simply and confidently with your external partners. The guest system makes it easy to involve external users while keeping full control over what they can see or do. Create personal groups to organize collaboration by project, client, or team—autonomously and efficiently. Guests and personal groups can be added to spaces or shares, with finely tuned access rights. You stay in control: each guest or group is linked to a designated manager for clear, decentralized management done smoothly.
Activity Tracking
Stay on top of activity in real time. Comment directly on files to streamline communication and speed up feedback. Get a quick view of recently modified or commented files, and take advantage of the notification system to stay informed. A shared real-time view for more effective collaboration.
Advanced File Manager
Optimize your workflow with a fluid and intuitive interface that makes it easy to manage your files using drag and drop, the window manager, and the smart clipboard, while benefiting from the offline task manager, gallery view, sorting, filtering, and an enhanced viewer, for a faster, clearer, and more efficient experience.
Smart Search
Equipped with a full-text search engine : no longer settle for searching your files by name, explore the actual content of all your documents (Microsoft Office, PDF, HTML, plain text…) to instantly find even the smallest piece of information. With support for including or excluding keywords and phrases, you can refine your searches to get precise results. Boost your productivity and clarity by uncovering the core of your data.
Real-time collaborative editing
The integration of OnlyOffice enables real-time collaborative editing of text documents, spreadsheets, and presentations directly online. It natively supports Microsoft Office formats and offers compatibility with OpenDocument formats, while fully respecting access rights and permissions defined via Sync-in, for smooth and secure collaboration.
