Nutrient SDK brings real-time document collaboration inside your app: one document, every reviewer, live, without building sync infrastructure or routing files through a third-party collaboration tool. Developers, product managers, and UX engineers use it to add multi-user review to contract review, technical drawing markup, on-site field notes, and team approvals. Nutrient Instant, running with Document Engine over WebSockets, syncs annotations, comments, and form data across users and devices on web, iOS, and Android. Threaded comments pin to regions or annotations and can be resolved or reopened. Viewer, commenter, and editor roles are set with JWT-based permissions and can change mid-session. Document Engine can be self-hosted, so documents and collaboration data stay in your environment, and collaboration shares one document model with annotation, editing, and signing.
