AppSheet

AppSheet, a Google product, is a no-code development platform that allows users to build applications and automations. It leverages AI, specifically Gemini, for app creation and to infuse intelligence into apps, which aligns with conversational AI and multimodal AI capabilities. The platform offers API integration for connecting with various data sources and services. Security features and governance policies are highlighted, indicating a safety and alignment framework. Furthermore, AppSheet provides enterprise-level solutions with advanced security, team management, and governance controls, directly matching the 'enterprise-solutions' feature. While it doesn't offer direct 'fine-tuning and custom models' in the sense of training large language models, it allows for significant customization of the apps built on its platform.
