What does LightOn do?
LightOn is an enterprise-grade AI search and reasoning platform designed to operate entirely within your organization's infrastructure. It allows companies to securely search and analyze their internal documents, images, technical diagrams, and data without sending sensitive information to external cloud services. The tool uses multimodal retrieval-augmented generation (RAG) to understand complex file formats and provide precise answers with clickable citations.
What sets LightOn apart is its focus on security and enterprise requirements. The platform runs completely behind your firewall, ensuring zero data exfiltration while maintaining strict access controls that mirror your existing permissions. It synchronizes with various data sources like SharePoint, Drive, and Confluence, keeping your knowledge base continuously updated. The system supports both developer-focused API integration and a ready-to-use white-label chat interface for business teams.
This tool primarily benefits large organizations with sensitive data compliance requirements, such as financial institutions, government agencies, and enterprises with proprietary technical documentation. Teams can use it to instantly find information across millions of files, cross-reference complex technical specifications, and maintain strict governance over who can access specific information within the organization.
