Coda

Coda is an all-in-one collaborative workspace that combines the functionalities of documents, spreadsheets, and applications. It integrates AI features, including conversational AI for content creation and querying, and a 'Coda Brain' for unifying company knowledge across various tools. Coda aims to help teams organize work, track projects, and automate tasks within its flexible document-based platform.

Coda is a strong match for the Retool concept. It offers extensive integrations with various tools (APIs and databases via 'Packs'), allows for significant customization through formulas and automations (code customization), and provides enterprise-grade security features like SSO and advanced access controls. While it's not explicitly a 'drag-and-drop UI builder' in the same sense as Retool's component library, it allows users to build applications and trackers with a visual interface. It also supports flexible deployments through its cloud platform and offers AI assistance, workflow automation, and audit logs.
