Legato serves as an AI-powered extensibility platform tailored for SaaS applications, enabling business users, partners, and internal teams to develop tools, applications, workflows, and AI agents directly within the platform using natural-language instructions and integrated creation features found in the SaaS interface without the need for coding. This no-code, AI-enhanced customization layer empowers users to craft functionalities such as new fields, automated workflows, data-driven agents, and app components directly in their product environment, allowing for a swift transformation of requests and innovative ideas into operational solutions without the delays associated with engineering or professional services. By shifting the focus of customization from a backlog-oriented development model to a self-service, AI-native approach, Legato incorporates creation capabilities that enable platforms to meet specific customer requirements while ensuring governance and compliance, thereby allowing extensions to operate securely and predictably within the primary application. Ultimately, this platform not only enhances user experience but also fosters a more agile and responsive development cycle.
