Everything Your Team Needs
Stop juggling multiple tools. Nucleus One combines project management, document management, and team collaboration in one modern platform.
Document Management
Store, organize, and find all your documents in one place. Full-text search with OCR capability lets you find content inside scanned documents and PDFs. Version control tracks every change with complete revision history. Secure sharing with granular permissions means you control exactly who sees what. Automated workflows can route documents for approvals, ensuring nothing falls through the cracks.
Project Management
Manage projects the way that works best for your team. Choose between Kanban boards for agile workflows, traditional task lists for simple tracking, or Gantt timelines for complex project visualization. Real-time collaboration means your entire team stays synchronized. Dependency mapping prevents bottlenecks by showing task relationships. Automated status updates powered by AI keep stakeholders informed without manual reporting.
Digital Signatures
Built-in e-signatures with complete legal compliance—no need for DocuSign or Adobe Sign subscriptions. Unlimited signature requests at no extra cost. Legally binding signatures with tamper-proof audit trails meet ESIGN Act and UETA requirements. Workflow signatures require sequential approvals from multiple parties. Signature templates save time on recurring document types like contracts, NDAs, and employment agreements.
Team Collaboration
Transform how your team communicates and coordinates. Real-time comments keep discussions contextual to the work. @mentions notify specific team members without unnecessary notifications for everyone. Activity feeds show what changed and who made the change. Task assignments with due dates and priority levels keep everyone clear on responsibilities. Threaded conversations prevent information from getting buried in back-and-forth exchanges.
Public Portals
Create branded client portals without needing a developer. Clients can upload documents, view project progress, and sign agreements—all without needing a Nucleus One account. Custom form submissions collect structured data automatically. Progress tracking lets external stakeholders stay informed. White-label options allow you to present it as your own product. Perfect for legal firms, agencies, and professional services collecting documents from multiple parties.
Enterprise Security
Bank-level encryption protects your data at rest and in transit. Role-based access control (RBAC) lets you define exactly what each team member can access. Detailed audit trails record every action for compliance and accountability. Single Sign-On (SSO) integration with your existing identity provider. HIPAA, SOC2, and GDPR compliance certifications built in—no additional setup needed for regulated industries.
